Raw GNSS Packet
This packet represents the raw data as it is received from the GNSS receiver. The
position is not corrected for antenna position offset and the velocity is not
compensated for the antenna lever arm offset. The INS position and velocity that are
in the other packets are corrected for antenna position offset and lever arm.
