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, Galileo) are under the control of the 
respective Governmental agency 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.
