Note 1: Set time is an internal 10 millisecond (T10) count since power-on initialisation enabled the processor interrupts. It is not used
to derive GPS time, but only serves to provide a sequence of events knowledge. The set time or T10 count references the receiver’s
internal time at which the message was created for output. The T10 range is approximately 71 weeks.
Note 2: The sequence number is a count that indicates whether the data in a particular binary message has been updated or
changed since the last message output.
Note 3: The satellite measurement sequence number relates the position solution data to a particular set of satellite measurements
found in binary Messages 1002 and 1007 (channel summary message and channel measurement message, respectively).
Note 4: j = 0 to 11

3.5.1.5 Message 1007 (channel measurement)
This message provides measurement and
associated data for each of the receiver’s
12 channels. The contents of the ‘channel
measurement’ message are described in
Table 3-9.
