Table 32: Time of PPS Digital Output Format
UTC offset (offset of UTC
time from GPS Time where
UTC time = GPS Time +
UTC offset)
Clock model status (PCS
clock model status where 0 is
valid and values
-20 to -1
implies that clock is in
process of stabilization)
Note: PPS time is the time of the previous 1PPS signal.
GNSS Ports
Some older versions of POS MV systems contain two separate GNSS receivers, referred to as primary
and secondary, while newer systems contain one dual antenna GNSS receiver. In either case the PCS
configures the GNSS receiver card(s) automatically for its own use.
The user may require access to the GNSS receiver directly to; 1) upgrade the receiver firmware or, 2)
supply corrections directly to the receiver rather than the Base GNSS input to POS.
All POS MV V5 systems provide a mechanism to switch COM3 and COM4 to connect directly to the COM
port on the internal GNSS receiver(s) by selecting that connection in POSView (see COM Port Set-up).
Newer systems also provide a dedicated “GNSS” port which is permanently connected to the COM port of
the internal GNSS receiver.
Physical Interface
COM ports 3 and 4 may be configured using the MV-POSView software to allow direct access to the
primary and secondary GNSS receiver cards. Table 33 lists the factory port settings.
