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.
