session

A period during which one or more GPS receivers log satellite data, including antenna information and start/stop times. There are two types of sessions: static and stop and go.

A static session consists of two independent, simultaneously collected occupations. The time duration where two occupations overlap defines a session. The session equals the baseline.

A Stop and Go session consists of data collected from a base station and a rover. The time duration where the data overlaps defines a session. The session consists of baselines (the time when the rover is stopped) and trajectories (the times when the rover is moving).
