COCOM limits
The U.S. Department of Commerce requires that all exportable GPS products contain
performance limitations so that they cannot be used in a manner that could threaten
the security of the United States. The following limitations are implemented on this
product:
performance limitations so that they cannot be used in a manner that could threaten
the security of the United States. The following limitations are implemented on this
product:
•
Immediate access to satellite measurements and navigation results is disabled
when the receiver velocity is computed to be greater than 1000 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.
