A.2
Receiver Characteristics
A.2.1
Input Signal
•
GPS L1 C/A code, 1575.42 MHz.
A.2.2
Timing Accuracy
GPS/UTC time
±
500
η
s rms (at 1-PPS output), when receiving 4 or more satellites (one satellite
if position is known within 25 meters.)
A.2.3
Position Accuracy (rms)
•
25 meters, SA (USA Department of Defense Selective Availability) OFF, 100 meters, SA ON.
A.2.4
Satellite Tracking
•
12 channels, C/A code (1575.42 MHz)
The receiver simultaneously tracks up to twelve satellites. Results from all tracked satellites are
averaged in Position-Hold Mode or, with Position-Hold Off, are determined by least-squares esti-
mation.
