8.0 Tools and Diagnostics
The Position and Orientation System for Marine Vessels (POS MV) provides
a diagnostics function to help solve some of the problems that may arise
when connecting the system within an integrated suite of survey equipment.
GNSS Configuration
Upon installation, the POS MV configures the GNSS receivers so that they
output only those messages used by the system. When necessary, the POS
Computer System (PCS) will reconfigure the receivers automatically if either
one ever loses its configuration for any reason.
Additionally, you can send the GNSS configuration message to the GNSS
receivers manually by selecting Tools, Configure GNSS from the MV-
POSView menu bar.
GNSS Reset
The MV-POSView Controller program allows you to send a reset command to
the GNSS receivers. To do this, select Tools, Reset GNSS from the MV-
POSView menu bar.
Once the reset command is initiated, the GNSS receivers will take
approximately two minutes before they return to the navigation mode and
POS MV can use their data.
Use the GNSS reset feature only as a final option if the receivers exhibit
inexplicable, uncharacteristic behaviour. Examples of such behaviour include
a failure to track satellites, a failure to compute or a failure to output a valid
navigation solution for an extended period. Before using the GNSS reset
