Setting GNSS Port as Reference

To provision the TimeProvider 5000 for GNSS, use the
command to select a Time mode. Use the
GNSS port state and GNSS parameters.
Note: Manual mode should not be used unless antenna location has
been accurately surveyed. See the
for for details about setting GNSS position parameters manually.
Track-Mode
The Priority setting for GNSS is for the GNSS port itself. However, the GNSS port
for the 090-50331-04 can receive Beidou and GPS satellite RF inputs. (Future
implementations of the IMC card may support RF inputs from other satellites.) The
GNSS track-mode parameter is used to specify the tracking priority for the GNSS
port.
