Data checksum
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 options list is a bit-encoded configuration word represented as an ASCII four-digit hexadecimal number:
bit 0 minimises ROM usage
bit 1 minimises RAM usage
bits 2-15 reserved
Table 3-11 Message 1011 (receiver ID)
3.5.1.7 Message 1011 (receiver ID)
This message is output automatically at start-up
after the receiver has completed its initialisation.
It can be used to determine when the receiver is
ready to accept serial input. Manual requests for
this message are also honoured. This message
consists of five 20-byte (two characters per word),
null-padded ASCII data fields. The contents of the
‘receiver ID’ message are described in Table 3-11.
