5.13 Message: MSG_RTCM_Corrections (Revise this as per VSC)
Use: The RTCM_Corrections message is used to encapsulate RCTM differential corrections for GPS and
other radio navigation signals as defined by the RTCM (Radio Technical Commission For Maritime
Services) special committee number 104 in its various standards. Here, in the work of DSRC, these
messages are "wrapped" for transport on the DSRC media, and then can be re-constructed back into the
final expected formats defined by the RCTM standard and used directly by various positioning systems to
increase the absolute and relative accuracy estimates produced.
