POS: Setting the Antenna Position
Function
This command allows you to enter the geographic coordinates
of the GNSS antenna. It is usually used to enter the position
of a base. If there is no computed position available from the
receiver when the command is applied, then the entered
position is used to initialize the receiver position in order to
speed up satellite tracking.
Depending on the last $PASHS,ANR command applied to the
receiver, the antenna position you enter will be either that of
the phase center, the ARP or the ground mark.
