Trimble R6 GPS and R8 GNSS Receiver Operation
12.3COCOM 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 the
Trimble R6 GPS and R8 GNSS receivers.
Immediate access to satellite measurements and navigation results is disabled when
the receiver’s velocity is computed to be greater than 1000 knots, or its altitude is
computed to be above 18,000 meters. The receiver continuously resets until the
COCOM situation is cleared.
