Galileo SV enable/disable record
The Galileo SV enable/disable record is used to enable or disable a selection of the 52 Galileo satellites. By default, the receiver is configured to use all satellites that are in good health. This record is useful for enabling satellites that are not in good health. Once enabled, the health condition of the satellite(s) are ignored, and the Galileo signal transmissions from the satellite(s) are considered when computing position solutions.
The following table shows the additional records provided when the Galileo SV enable/disable record is included with Command Packet 64h.
