Description

Dark Gray

The channel is idle.

Black

The channel is searching for a satellite or there is an unknown error.

Magenta

The channel is in wide frequency band pull-in state.

Red

The channel is in frequency lock loop or narrow frequency band pull-in state or the channel is locked to a satellite but the ephemeris data indicates the satellite is unhealthy.

Blue

The channel is in alignment mode or the channel is locked to a satellite but the ephemeris data is old (not updated within the last 3 hours) or the channel is locked to a satellite but ephemeris data for the satellite has not yet been received.

Dark Green

The channel is locked to a satellite and the observations are good.

Light Green

The channel is attempting to re-aquire the satellite.

Green Yellow

The channel is attempting a fast re-aquisition or steering or the channel is locked to a satellite but no compatible ionospheric or differential correction is available for the satellite.

Yellow

The channel is locked to a satellite but there was an anomaly during computation of the satellite's position.

Cyan

The channel is locked to a satellite but an error has occurred. Possible errors include a satellite coordinate error, an elevation error due to the satellite being below the cut off angle, large misclosure due to an excessive gap between the estimated and actual positions or an invalid IODE (Issue of Data Ephemeris).

Light Gray

The channel is locked to a satellite but the satellite has been locked out by the user.

Orange

The channel is locked to a satellite but there is no observation.
