Note 1: Set time is an internal 10 millisecond (T10) count since power-on initialisation enabled the processor interrupts. The set time
indicated is at the time the message is submitted to the output queue.
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: The data displayed by this field is not valid until the receiver is in navigation mode.
Table 3-10 Message 1009 (ECEF position output)
3.5.1.6 Message 1009 (reduced ECEF position
status output)
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 3-10.
