4 SBF Reference
GEOCorrections
Number:
5935
"OnChange"
interval: default PVT output rate (see 4.1.8)
This block contains the SBAS corrections that the receiver has applied to the pseudoranges
used in the PVT computation computed at the epoch specified in the
TOW
and
WNc
fields.
The PVT solution itself can be found in the
PVTCartesian
or
PVTGeodetic
blocks.
The corrections are based on the messages received from an SBAS satellite. They compen-
sate for the following errors:
• Satellite orbit
• Satellite clock
• Ionospheric delay.
