Health of Receiver Report
This packet provides information about the satellite tracking status
and the operational health of the receiver. The receiver sends this
packet after power-on or software-initiated resets, in response to
packet 26, during an update cycle, when a new satellite selection is
attempted, and when the receiver detects a change in its health.
Packet 4B is always sent with this packet. The data format is given in
the following table.
