Notes:
(1) After this error is detected, its bit remains set until the GPS receiver is reset.
(2) This bit follows the current status of the antenna feed line fault-detection circuitry. Since
GPS receiver has an integral antenna assembly, this information of little import; it is only
shown for the sake of completeness, being important for sensors with separate antennas.
(3) This bit is ‘1’ if the last computed reference frequency error indicated that the reference
oscillator is out of tolerance. (Packet 2D requests the oscillator offset and packet 4D returns
the oscillator offset to the user.)
(4) this bit is always set as the GPS receiver battery backup is not installed.

The data is for the satellites that are currently being tracked:
