This command implements position averaging for base stations. Position averaging continues for a specified number of hours or until the estimated averaged position error is within specified accuracy limits. Averaging stops when the time limit or the horizontal standard deviation limit or the vertical standard deviation limit is achieved. When averaging is complete, the FIX POSITION command is automatically invoked. See the FIX command.

If differential logging is initiated, then issue the POSAVE command followed by the SAVECONFIG command. The receiver averages positions after every power on or reset. It then invokes the FIX POSITION command to enable it to send differential corrections.

The POSAVE command can be used to establish a new base station, in any form of survey or RTK data collection, by occupying a site and averaging the position until either a certain amount of time has passed or position accuracy has reached a user-specified level. User-specified requirements can be based on time or horizontal or vertical quality of precision.
