SuomiNet is an international network of GPS receivers, configured and managed to generate near real-time estimates of precipitable water vapor in the atmosphere, total electron content in the ionosphere, and other meteorological and geodetic information.

SuomiNet Participation Procedure

NOTE: All SuomiNet systems have been allocated. There are no longer any systems available for new participants.

• How to Proceed

• Site List

SuomiNet Site Installation Instructions

• Connect the GPS Receiver and Computer Using These Instructions

• Installation questions? Contact UNAVCO (supportunavco.org).

• Notify the UCAR SuomiNet Data Analyst Teresa VanHove (vanhoveucar.edu) when the system is connected and on-line. Include the computer IP address.

How to Access SuomiNet Data

• Geodetic data can be accessed via FTP from the UNAVCO Data Archive, as daily RINEX files.

• SuomiNet participants can access their site data, and data from other SuomiNet sites by subscribing to the LDM service from UCAR. A separate computer is required to run LDM, since the SuomiNet computer is for data collection only.

  1. Install LDM on your local computer. See the Unidata LDM Support Page.

  2. Notify the UCAR SuomiNet Data Analyst Teresa VanHove (vanhoveucar.edu) when your computer is set up to receive SuomiNet data. Include the computer IP address.

  3. Configure the "pqact.conf" file on your local machine.

• Participants may also directly access data from their own site via LDM. A separate computer is still required to run LDM, since the SuomiNet computer is for data collection only.

  1. Install LDM on your local computer. See the Unidata LDM Support Page.

  2. Change the "ldmd.conf" file on your local SuomiNet computer to allow data access from the local computer.

  3. Configure the "pqact.conf" file on your local machine.
