4 SBF Reference
RTCMDatum
Number:
4049
"OnChange"
interval: block generated each time a set of transformation
parameters is received
This block reports the source and target datum names as transmitted in RTCM 3.x message
types 1021 or 1022. It also reports the corresponding height and quality indicators.
If a service provider only sends out message types 1021 or 1022, this block is trans-
mitted immediately after reception of MT1021 or MT1022. If message types 1023 or 1024
are also sent out, this block is transmitted after the reception of these messages and the
field is set accordingly.

transformation:
Bits 0-3: horizontal quality indicator:
0:
Unknown quality
