4.2.3 GBS
4.2.3.1 GNSS Satellite Fault Detection
Message
GBS
Description
GNSS Satellite Fault Detection
Firmware
Supported on:
•
u-blox 9 with protocol version 27
Type
Output Message
Comment
This message outputs the results of the Receiver Autonomous Integrity Monitoring
Algorithm (RAIM).
• The fields
errLat
,
errLon
and
errAlt
output the standard deviation of the position
calculation, using all satellites which pass the RAIM test successfully.
• The fields
errLat
,
errLon
and
errAlt
are only output if the RAIM process passed
successfully (i.e. no or successful edits happened). These fields are never output if 4 or
fewer satellites are used for the navigation calculation (because, in such cases, integrity
can not be determined by the receiver autonomously).
• The fields
prob
,
bias
and
stdev
are only output if at least one satellite failed in the
RAIM test. If more than one satellites fail the RAIM test, only the information for the
worst satellite is output in this message.
