•
Immediate access to satellite measurements and navigation results is disabled
when the receiver velocity is computed to be greater than 1,000 knots, or its
altitude is computed to be above 18,000 meters. The receiver GPS subsystem
resets until the COCOM situation clears. As a result, all logging and stream
configurations stop until the GPS subsystem is cleared.
