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:
• 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.
