RTCA Message Lengths

Affected Products: OEM3, OEM4, OEMV Native RTCA message lengths can be calculated as follows:

RTCAREF: fixed length 24 bytes (192 bits)

RTCAOBS: variable length message length (bits) = [140 + (92*obs)] message length (bytes) = [140 + (92*obs)]/8 255 bytes maximum

RTCA1: variable length message length = 11 + (6*obs) 83 bytes maximum

RTCAEPHEM: fixed length 102 bytes (816 bits)
