s
Event time offset with respect to
TOW
, including the potential delay
specified with the
command.
The time of week of the external event is given by:
t
ext,rx
[s] =
TOW
/1000 +
Offset
t
ext,rx
refers to the receiver system time scale. Use the
RxClkBias
field to convert this time to the GNSS time scale.

Receiver clock bias at the time of event. The clock bias is relative to the
time system of the last PVT computation (see the
TimeSystem
field of
the
PVTCartesian
or
PVTGeodetic
blocks). To get the time of week
of the external event in GNSS time, use:

.
The accuracy of the clock bias is dependent on the age of the last
PVT solution. When the receiver has been unable to compute a PVT
during the last 10 minutes, this field is set to its Do-Not-Use value.

Age of the last PVT solution. If the PVT age is larger than 10 minutes
(600s), this value is clipped to 600.
