Data Output

TTT: Event Marker

Content This message delivers the exact GPS time, to within

1 μsecond, when an external event is detected.

The message is sent through port B, where the event marker

input pin is located, and not through the port specified by the

$PASHS, NME command.

The message is therefore independent of the NMEA output

rate. It can be output at a faster or slower rate than the NMEA

rate, depending on the recurrence of the event.

The message is as follows:

$PASHR,TTT,d1,m2*cc

d1 and m2 are described in the table below.

Example $PASHR,TTT,3,18:01:33.1200417*AC
