Scaling Name Unit Description
0 U1 - msgVer - Message version (=0 for this version)
1 U1 - numTrkChHw - Number of tracking channels available in
hardware (read only)
2 U1 - numTrkChUse - (Read only in protocol versions greater than 23)
Number of tracking channels to use. Must be >
0, <= numTrkChHw. If 0xFF, then number of
tracking channels to use will be set to
numTrkChHw.

Start of repeated block (numConfigBlocks times)
4 + 8*N U1 - gnssId - System identifier (see Satellite Numbering)
5 + 8*N U1 - resTrkCh - (Read only in protocol versions greater than 23)
Number of reserved (minimum) tracking
channels for this system.
6 + 8*N U1 - maxTrkCh - (Read only in protocol versions greater than 23)
Maximum number of tracking channels used for
this system. Must be > 0, >= resTrkChn, <=
numTrkChUse and <= maximum number of
tracking channels supported for this system.
7 + 8*N U1 - reserved1 - Reserved
8 + 8*N X4 - flags - bitfield of flags. At least one signal must be
configured in every enabled system. (see graphic
below)
