Service Signal:
www.cnavgps.com/satellite_calculator
Most antenna’s have better gain when the
satellite is high in elevation. Expect tracking
performance to fade as the satellite lowers in
elevation. It is not unusual to see 10dB
difference in antenna gain (which translates into
signal strength) throughout the entire elevation
tracking path.
A clear line of sight between the antenna and
the local INMARSAT satellite is required to track
the C-Nav Correction Service signal.
INMARSAT satellites are geo-synchronized
35,786kms above the Equator, currently at
Longitudes:
142
° West, 97.65° West, 15.5° West
