5.15.1.1 Satellite Measurements for RRLP
UBX-RXM-MEASX
Message
Satellite Measurements for RRLP
Description
Supported on:
Firmware
• u-blox 9 with protocol version 27
Periodic
Type
The message payload data is, where possible and appropriate, according to the Radio
Comment
Resource LCS (Location Services) Protocol (RRLP) [1]. One exception is the satellite and
GNSS ids, which here are given according to the
satellites have to be selected and their satellite ID translated accordingly [1, tab. A.10.14]
for use in a RRLP Measure Position Response Component. Similarly, the measurement
reference time of week has to be forwarded correctly (modulo 14400000 for the 24 LSB
GPS measurements variant, modulo 3600000 for the 22 LSB Galileo and Additional
Navigation Satelllite Systems (GANSS) measurements variant) of the RRLP measure position
response to the SMLC.
