GPS Tab

The GPS tab monitors the hardware GPS receiver used for position, UTC timing, PPS, and ADC clock correction.

Receiver Solution

The solution table reports:

• acquisition state
• satellites tracked and considered good
• total fixes and fixes per minute
• receiver run time and time to first fix (TTFF)
• UTC offset
• measured ADC clock
• latitude, longitude, and altitude
• a map link for the reported position

The GPS tab is primarily diagnostic. ADC correction policy is configured on Config > Clocking and Config > ADC Behavior.

Satellite Channels

The channel table shows each tracking channel, satellite PRN, ephemeris age, acquisition/tracking state, and RSSI. The satellite history and azimuth/elevation view help diagnose:

• a disconnected or poorly placed GPS antenna
• weak satellite visibility
• stale ephemeris data
• insufficient satellites for a stable timing solution

Allow several minutes after startup for the receiver to download satellite data and produce its first fix.
