Notes: 1) Satellite information may require the
transmission of multiple messages. The first
field specifies the total number of messages,
minimum value 1. The second field identifies
the order of this message (message number),
minimum value 1.
2) A variable number of “PRN-Elevation-Azimuth-
SNR” sets are allowed up to a maximum of four
sets per message. Null fields are not required
for unused sets when less than four sets are
transmitted.
