1. Introduction

1-1 Assisting with GPS in Geosciences Research

This manual contains information prepared by the UNAVCO to assist principal investigators in the successful preparation and execution of research projects utilizing the Global Positioning System (GPS). UNAVCO is sponsored by the National Science Foundation (NSF) and the National Aeronautics and Space Administration (NASA) to make GPS resources available for geoscience research.

UNAVCO is a national program, governed by universities and funded by the National Science Foundation and NASA, to assist university researchers using Global Positioning System (GPS) technology in Earth sciences applications. UNAVCO provides information, support, and scientific infrastructure to principal investigators making use of GPS satellites for Earth science and related research. The aim of UNAVCO is to extend the capabilities of the university community, nationally and internationally, to better understand the behavior of the Earth and the global environment, and to foster the transfer of knowledge and technology for the betterment of life on Earth.

1-2 What is GPS?

The Global Positioning System (GPS) is a constellation of 24+ satellites designed for navigation and positioning. GPS satellites are to the space age as lighthouses were to the sailing age. Although GPS was developed mainly for military use, valuable civilian and scientific applications have been developed.

1-3 Why UNAVCO?

In the early 1980s:

  • GPS was being established as a powerful space-based system for military navigation.

  • The earth sciences research community recognized that GPS has a wide variety of valuable geosciences applications.

  • University researchers lacked the equipment and expertise to use GPS effectively.

To address this opportunity, university researchers formed a consortium to establish a pool of GPS equipment and provide technical assistance to investigators working in high-accuracy differential GPS surveying. The earth sciences community built the UNAVCO program on the concept of shared responsibility between universities and the UNAVCO Facility, with encouragement and funding from the National Science Foundation.

UNAVCO began establishing a GPS equipment pool and providing technical and field support to university investigators in 1986. Since that time, UNAVCO has assisted scores of researchers in hundreds of field projects employing state-of-the-art GPS equipment and methods.

1-4 UNAVCO Today

UNAVCO’s primary mission is to provide GPS equipment and technical support to university-based investigators. Applications include the study of plate tectonics, earthquakes, crustal motion, volcanoes, sea level, ocean currents, ice dynamics, and atmospheric sensing. More than 100 universities and research institutions participate as members of UNAVCO. Investigators and students at these institutions have access to a variety of equipment and support services.

Continuous GPS Station Support. UNAVCO provides complete support and turnkey solutions for investigators using continuously tracking GPS stations and networks for the highest accuracy applications of GPS. This support includes standardized power and communication solutions, discounted GPS equipment prices, network monitoring and maintenance, daily data retrieval, data management software, and archiving services.

GPS Equipment for Campaign Support. High accuracy GPS receivers and auxiliary equipment are available to the community through the UNAVCO equipment pool. Although GPS equipment is complex and a variety of user options are available, UNAVCO equipment is standardized. This ensures simplified training, operations, and data analysis, as well as higher scientific productivity and quality. Participating investigators who are applying GPS to their research interests can obtain assistance in planning, training, logistics, field operations, as well as data analysis and archiving.

Technical Assistance. Investigators can also obtain assistance in troubleshooting, accuracy improvement, new applications, software development, equipment testing, data analysis and other technical areas.

Archiving Services. The scientific value of high-accuracy geophysical positioning data tends to increase with the passage of time. UNAVCO maintains a map-oriented relational database to archive GPS data and make it readily available to investigators.

Rapid Deployment. Unique research opportunities often precede and follow major geophysical events such as earthquakes and volcanic eruptions. Equipment and technical support is often provided to investigators on short notice following major events. Serving the rapid deployment needs of the community is a continuing priority of UNAVCO.

1-5 Who Guides UNAVCO?

Program guidance for UNAVCO is provided by a board of directors elected by member institutions to represent the university community. The UNAVCO Facility is managed by the University Corporation for Atmospheric Research (UCAR) in Boulder, Colorado. UCAR is a consortium of universities in the United States and Canada. UCAR oversees a wide range of programs and facilities that serve its members and the world scientific community. UCAR also manages and operates the National Center for Atmospheric Research (NCAR).

The UNAVCO program is funded under a peer-review grant from the National Science Foundation and under contract from the National Aeronautics and Space Administration.

2. Guidelines for Use of UNAVCO Resources

Principal Investigators (PIs) are encouraged to follow these guidelines in order to facilitate the smooth planning and execution of projects. Note that failure to comply with the 30 day Purchase Order (PO) deadline (see Section 4-6, 30 Day Deadline, Chapter 4) may lead to downgrading in priority, postponement, or cancellation of UNAVCO support for your field project.

2-1 Proposal Preparation

  • Contact UNAVCO for budget and logistics advice at least one month before proposal submittal.

  • In the proposal, specify which UNAVCO resources are being requested. Include the location of the project, the number of receivers required, the type of receivers required, and the start and end dates of the project.

  • Have the proposal budget reviewed by UNAVCO before submitting the proposal to the funding agency. UNAVCO can provide a letter of support to accompany the proposal, stating that UNAVCO has reviewed the GPS objectives of the proposal and is prepared to provide GPS support consistent with that requested in the proposal.

  • Send a copy of the proposal to UNAVCO.

  • Submit an on-line request for support to UNAVCO for the proposed GPS project. This allows the project to be tentatively scheduled prior to a funding announcement.

2-2 After Receiving Funding Announcement

  • Inform UNAVCO of proposal status and award number.

  • Solicit UNAVCO’s input if preparing a revised budget.

2-3 Project Scheduling

The project will be scheduled by UNAVCO when both (1) the support request has been received by UNAVCO, and (2) the project is funded by a source (normally NSF or NASA) that UNAVCO is mandated to support.

2-4 Project Planning

  • Follow UNAVCO Scheduling Procedure (see also Section 3-1, Scheduling Procedure).

  • Ensure the purchase order (PO) for UNAVCO services reaches the UNAVCO Administrator at least 30 days before the start of the project.

  • Contact the UNAVCO Facility with questions.

2-5 During Project

  • A UNAVCO engineer will accompany the project. The UNAVCO engineer is responsible for the security and proper use of UNAVCO equipment. In the case of disputes that impinge on the welfare of the personnel or equipment, the UNAVCO engineer has the final authority.


    A designated research organization representative (Agent) will assume responsibility for the security and proper use of UNAVCO equipment. The Agent will also be responsible for training others on the proper use of the equipment in accordance with UNAVCO procedures.

  • Apart from this, the PI (or other appointed leader of the field team) has responsibility for the daily operation of the project.

  • The PI is responsible for cost overruns.

2-6 Data Archiving

  • All GPS data from projects wholly or partly funded by NSF-EAR or NASA must be archived at the UNAVCO Facility. Archive accessibility is based on the PI’s arrangements (see also Section 7-2, Timing and Data Management Logistics). Data include, but are not limited to, all raw field data (CDs, DVDs, or other storage media) and legible copies of all field logs. Policies for deposit and release of data into/from the archive are described in Chapter 7.

  • Deposit of other data sets into the archive is encouraged. The PI is responsible for making the necessary arrangements for archiving of data with the project field engineer.

2-7 Emergency Use of UNAVCO Equipment

One of UNAVCO’s principal objectives is to provide GPS equipment for the detection of post-seismic strain associated with major earthquakes. Deployment of UNAVCO equipment within a day or so of the event is important. Following a major earthquake, any researcher who believes that crucial strain measurements are likely to be obtained if GPS equipment were immediately deployed should contact UNAVCO immediately.

Users of UNAVCO equipment are advised that re-allocation of scheduled equipment may occur in the event of a major earthquake. Rescheduling of equipment will be given top priority for investigators who suffer delay of scheduled use of UNAVCO equipment.

3. UNAVCO GPS Project Schedule

3-1 Scheduling Procedure

These procedures must be followed to ensure UNAVCO support:

  • An on-line (kb.unavco.org) request for support from the Principal Investigator (PI) should be received by the UNAVCO Facility 120 days before the start of a project. Information required includes the proposal name, proposal number, funding source, program manager, purpose of the project, the location of the project, the number of receivers required, the type of receivers required, and the start and end date of the project and field dates. Preliminary requests may be submitted to UNAVCO before notification of funding award.

  • UNAVCO will provide the PI with prompt written confirmation or denial of support upon receipt of the on-line support request.

  • Depending on the magnitude of the project, PIs who receive approval to use UNAVCO resources may be required to schedule a planning meeting with the UNAVCO staff 120 days before observations are to begin. UNAVCO may waive this requirement under special circumstances. Additional reviews should occur 90, 60 and 30 days before the campaign. Purchase orders for UNAVCO services must be received 30 days before the campaign.

  • Schedule conflicts and allocation of UNAVCO resources will be handled by UNAVCO with advice from the appropriate program sponsor.

5. Agent Projects

In many cases the PI receives equipment and training from UNAVCO, but no direct project support from a field engineer. Such projects are called “Agent Projects”, and a designated research organization representative (Agent) assumes responsibility for equipment security and damage, operator training, data acquisition, GPS operator safety, and logistic support. A signed “UNAVCO Equipment Loan Agreement” is required for all Agent projects. Agent projects differ from those supported by a UNAVCO field engineer in several ways:

  • There is usually no need to set up a Purchase Order with UNAVCO.

  • UNAVCO is not directly involved in field logistics issues, although consultation may be provided.

This chapter contains issues specific to Agents managing UNAVCO supported GPS field projects. The Agent should also review the rest of the UNAVCO Investigator’s manual.

5-1 UNAVCO Equipment Loan Agreement

The Equipment Loan Agreement spells out the responsibilities of the PIs research organization when borrowing UNAVCO equipment. The primary responsibilities of the agreement are:

  • The research organization is responsible for the full cost of repair or replacement of any of the equipment that is damaged, lost, confiscated, or stolen from the time it assumes custody until it is returned to UNAVCO. It is the research organization representative’s responsibility, before departing the place or country of use, to ensure that the equipment has cleared customs and is in shipment to UNAVCO.

  • The Agent shall be responsible for the proper use and deployment of the equipment loaned by UNAVCO. The Agent shall be responsible for training others participating in the research project on the proper use of the equipment in accordance with UNAVCO procedures.

  • The Agent shall be responsible for the safe packaging, proper import and export procedures, shipping and receiving, and proper operation and use of the equipment loaned by UNAVCO.

  • Delivery and return transportation expenses shall be paid by the research organization being loaned the equipment. These expenses shall include the cost of shipment of the equipment to the research location, the return of the equipment to UNAVCO, and equipment insurance during the shipping.

  • In the event UNAVCO has to make arrangements for the return of the equipment, the research organization shall be responsible for all costs incurred by UNAVCO, including labor costs, to obtain the return of the equipment.

  • All maintenance, except as prescribed in the UNAVCO operating procedures, shall be performed by authorized UNAVCO personnel. Any unauthorized maintenance voids all original equipment warranties. The research organization shall be liable for the cost of purchasing a new warranty for the equipment if unauthorized maintenance is performed on the equipment.

  • It shall be the research organization’s duty at its expense to comply with all country, federal, state, county, and municipal laws, ordinances, and regulations, if any, applicable to the work being performed with this equipment and to secure all local and/or state/country licenses or permits required to use this equipment. The research organization shall hold UNAVCO harmless from all damages of any nature whatsoever that they may suffer as a result of the research organization’s failure to do so.

5-2 Key Agent Issues

5-2.1 Operator safety is the Agent’s first priority.

The Agent should be aware of all possible safety issues, both political and natural. The Agent should maintain a daily contact schedule where operators can contact them if necessary.

5-2.2 Equipment safety is the Agent’s second priority.

  • Packing and repacking of equipment is important and should be explained in detail. In the past equipment has returned from Agent projects packed incorrectly resulting in damage (i.e. bent antenna plane or crimped antenna cables). Be sure that all operators know how to pack equipment prior to deployment.

  • Use of UNAVCO equipment should follow these guidelines.

    The Agent:

    1. Will not release equipment to an operator until they are fully trained.

    2. Will keep track of the equipment inventory (i.e. have a complete copy of the manifest).

    3. Will not jeopardize the agreed return schedule of the equipment.

    4. Will assure proper cleaning, checking the inventory and repacking of all equipment.

    5. Will report all lost or broken equipment at the end of the project. Contact the UNAVCO Facility immediately if a receiver appears broken. UNAVCO may be able to troubleshoot the problem and get the receiver working again. Clearly mark all broken equipment (flagging is good to use for this). Make a list of equipment and FAX to the UNAVCO Facility along with return shipping information.

    6. Will check that equipment is correctly packed and inventoried for return customs clearance. This is particularly important for returning import back into the U.S.

5-2.3 Meeting project goals is the Agent’s third priority.

Although this goal is listed third it is an important goal. The UNAVCO Facility will provide any preplanning assistance necessary to successfully meet the proposed goals of the project. In addition, the other chapters of this manual will provide helpful information.

5-3 Training

5-3.1 Operator Training

The Agent agrees to train others who will be using UNAVCO equipment. This includes confirming the ability, competence, and commitment of all of the operators. The Agent should understand all points in the training outline and be able to relay these points to the observers.

5-3.2 Optional Training

  • QC the data.

  • Specialized or minor repairs to the equipment excluding opening the receiver or the antenna.

  • Calibrate tribrachs.

5-4 Project End

A list of the data including disks, log sheets and site descriptions must be forwarded to the UNAVCO archive immediately following the project. Copies of the data must arrive at the UNAVCO archive within one year of the project, in accordance with the UNAVCO data policy (kb.unavco.org).

6. UNAVCO Project Checklist

The following is a list of items to aid Principal Investigators (PIs) in preparing for domestic and international GPS projects that utilize services provided by the UNAVCO Facility. This document lists the items that need to be addressed in outline form for the Initial Planning Meeting and subsequent meetings with UNAVCO. Although some of these items will be handled by the UNAVCO project engineer, all items should be discussed at the Initial Planning Meeting. Agent project PIs will also find this list useful for managing their own projects.

11 UNAVCO Data Management Guidelines

11-1 Introduction

UNAVCO has developed a comprehensive data management strategy to safeguard the present and future scientific value of GPS project data. This strategy encompasses most aspects of a typical project. It includes pre-project planning, data acquisition, conversion and verification in the field and at the Facility, and long-term archiving and data retrieval. The process involves project investigators, field operators, and Facility field engineers and archiving staff who are most familiar with the data. UNAVCO’s data management strategy supports new modes of operation including continuously operating networks and mixed mode occupation strategies for regional GPS geodesy. UNAVCO’s goal is to provide a flexible, reliable service that meets the needs of the expanding users of the UNAVCO Facility.

11-2 Data Management Timeline

UNAVCO deadlines for data management are designed to meet NSF and NASA guidelines on data accessibility. At present, NSF requires that data be made available to the public one year after the project ends. NASA requires that data be made available six months after the project ends. To preserve the data integrity and to meet these deadlines, the data should be archived immediately after return from the field. Data are made public at the specified deadlines, not at the time of archiving. Exceptions can be made (section b.) at the request of the PI. UNAVCO will represent PI’s needs in these matters to the Board of Directors and the sponsor whenever necessary.

  • The Initial Planning Meeting and subsequent meetings will be used to establish the PI’s requirements regarding data security in the archive (see section 11-4) and conditions for accessing the data from the archive. The PI will consult with the field engineer and, if necessary, the UNAVCO archivist, to determine current standards for submitting the data to UNAVCO.

  • Unless otherwise arranged by the PI, the project data will be archived upon the completion of the field operations (the PI may request alternative arrangements subject to approval by UNAVCO). The UNAVCO Board of Directors and NSF and NASA guidelines will be used to determine data availability. Data include raw data, RINEX data, meta-data (descriptions of and information about data and sites such as file names, antenna heights, and general locations and dates), and processed results. Generally this means that a web table containing information about the project will be readily accessible to the community. Requests for the data prior to the deadline noted above are met based on the PI’s written statements (see section 7-4). After the specified deadline passes the data will be released without further PI notification. Requests for data are met as quickly as possible based on resources.

11-3 Media

The UNAVCO engineer will recommend a media source and will acquire media, labels and forms used in the campaign. Typical options include CD-RW, DVD, and external hard drives.

11-4 Information to Provide UNAVCO Before Campaign Begins

  • Campaign name (a few words, e.g. "South Pacific, 1990")

  • Principal Investigators (names, addresses, e-mail, etc.)

  • Other Investigators (students who will be heavily involved, etc.)

  • Primary contact (chosen from above lists, preferably one name)

  • Security level of the data (levels 1-3 require prior approval by the funding agency and the UNAVCO Board of Directors):

    1. May not be archived.

    2. May be archived but no information other than the campaign’s existence will be disclosed to the community without the PI’s written approval.

    3. May be archived and the general nature of the campaign (map area, number of sites, site names, low precision site coordinates) can be browsed by the community but no data files or site descriptions distributed.

    4. May be archived and released to any who request it, in accordance with the UNAVCO data policy.

  • List of sites to be occupied in the form of site abbreviation (four character ID) and brief site description including mark stamps and description.

    Example: BOLD = 826m W/SW of intersection of Baseline Rd. and Broadway Boulder, Colorado, 39.97 N, 254.667E, mark stamp "Slater" on 1.5 inch diameter circular brass NGS monument.

  • For each site give approximate dates and times of each session. Use UT for times by default; otherwise specify time zone and offset. Specify dates in an unambiguous format (do not use a number for the month).

    Example: BOLD 0800 > 1200, 2000 > 2400 10-NOV-92 > 17-NOV-92

11-5 Information to Send to UNAVCO After Campaign Ends

  • Media: Most media are supported by UNAVCO. Current support includes zip, optical, CD, DVD, and floppy disks, PCMCIA cards, hard drives, tapes, and optical platters. Media must be clearly labeled with the contents, and in the case of multiple site media storage, accompanied by a list of what is contained on the media and the directory structure. Additionally, for multiple site media storage, UNAVCO provides tools that will store the verified data (RINEXed) along with the raw data.

  • Media documentation: Each disk or cassette should be clearly labeled with a unique name incorporating the campaign name, site abbreviation and the date of the session. Use the same system for the entire campaign. In addition, please send separately a list of cassettes/floppy disks, etc. using the same identification system. The UNAVCO field engineer will supply the labels, media and forms, or work with the PI to handle special request.

  • Session Logs: The standard forms should be used for the session logs and should be filled out completely. Please label these forms with the same system that is used for the media, if possible. Ensure that the copies submitted to UNAVCO are legible and complete. Also, ensure that the identification information is consistent between the log sheets and the cassette or disk media.

  • Input and output format: For each type of receiver in the project, provide the version of the recording firmware that was used. Note that translation cannot begin until this information is provided and that the log sheets often do not arrive until months after the cassettes or floppies. Please specify output format desired. Note that some formats may not be available for some receivers. You are encouraged to request data in RINEX format, though other formats will be considered.

  • Storage of materials: All the materials will be stored at the UNAVCO archive by default. If this is not desired, please specify an alternate arrangement.

11-6 Extracting Data from the Archive

A catalogue of archived data is available on the UNAVCO web site. The directory, or browse file, is a listing of campaigns and general information about the region of the campaign and the data accessibility (security level). The data are accessible based on the previous arrangements of the original PI at the time of the Initial Planning Meeting.

To request data, send an e-mail to archive@unavco.org. Include the name of the campaign, site name, date and times of interest, and any other details. UNAVCO archive personnel will respond with information concerning data availability. Data may also be requested by regular letter mail to the UNAVCO Archive.
