This page shows satellites being tracked by GPS receiver and associated information.

SAT ID: (Satellite Identification Number): Identification number for GPS satellite

ELV: (Position Elevation): Elevation in degrees above horizon for GPS satellite position

AZM: (Position Azimuth): Azimuth in degrees from true North for GPS satellite

L1 SNR: (L1 Signal to Noise Ratio): Signal strength for L1 GPS signal (signal to noise ratio)

L2 SNR: (L2 Signal to Noise Ratio): Signal strength for L2 GPS signal (signal to noise ratio)

Status: (GPS Signal Status): Status of GPS signal

• Search: searching for satellite signal
• Track: tracking satellite signal and using it for positioning
• OK: tracking satellite signal and using it for positioning
• OK SF1: tracking satellite signal and using it for positioning with STARFIRE signal frequency
• OK SF2: tracking satellite signal and using it for positioning with STARFIRE dual frequency
• OK RTK: tracking satellite signal and using it for positioning with STARFIRE RTK signal
