Technical Data Declaration (Jan 1997)
The Contractor, NavCom Technology, Inc., hereby declares that, to the best of its
knowledge and belief, the technical data delivered herewith under Government contract
(and subcontracts, if appropriate) are complete, accurate, and comply with the
requirements of the contract concerning such technical data.
Global Navigation Satellite System
Global Navigation Satellite Systems (i.e., GPS, GLONASS) are under the control of the
respective Governmental agencies, and the operation of these satellites may be changed
at any time without warning.
GPS Selective availability (S/A code) was disabled on 02 May 2000 at 04:05 UTC. The
United States government has stated that present GPS users use the available signals at
their own risk.
The U.S. State Department International Traffic in Arms Regulations (ITAR) regulations
limit the performance of commercial GNSS products. As a result, access to satellite
measurements and navigation results will be limited from display and recordable output
when predetermined values of velocity and altitude are exceeded. These threshold values
are far in excess of the normal and expected operational parameters of the SF-3050
GNSS Sensor.
