Data Logging

The Data Logging pages are used to manage the logging of GPS observation data to internal memory. These pages are used to manage Sessions, enable or disable the AutoDelete and Power Saving modes, and view, download, or delete logged data files.

The Data Logging Status page provides a global summary of the state of the data logging system. All currently defined Sessions are listed in the Session Status Table, which lists which Sessions are currently logging, and can be used to enable or disable specific Sessions. Also shown is the status of the AutoDelete system and the Power Saving Mode. Links are provided to edit these controls and create or edit Sessions.

Sessions

A Session is a process that logs data to one or more files. Each Session is defined with various controls that specify the type of data to be logged, the schedule for that logging, and the naming convention to be used for saving the data to files. A new Session is created from the Data Logging Status page by clicking on Create a New Session. An existing Session may be modified by clicking the Session's Name in the Session Status Table or by selecting Edit Sessions. Any number of Sessions may be defined, and multiple Sessions may be active at the same time. The following parameters are defined when creating or editing a Session.

Note that there is no design imposed limit on the number of Sessions that may be created, but it is possible to exceed system performance limits by creating a large number of high data rate Sessions that are active at the same time.

A Session may be deleted by editing the existing Session and selecting the Delete button at the bottom of the page.
