This article explains the GPS:Arbiter time synchronization format. Any GPS receiver may be used as a time synchronization source as long as the receiver outputs the ASCII time string every second and has On Time Mark (OTM).
During normal operation of a GPS time synching system, time signals are sent out once per second as an ASCII string containing the time. The ASCII time string for GPS:ARBITER and GPS:TRUETIME/DATUM is as follows:
Format: <SOH> Hex 01 The start bit of the <SOH> character is transmitted on time.
Q Time quality indicator. May be represented by:
space Locked, maximum accuracy
. (ASCII 46) Error < 1 microsecond
* (ASCII 42) Error < 10 microseconds
# (ASCII 35) Error < 100 microseconds
? (ASCII 63) Error > 100 microseconds
