Testing the internal GNSS and other circuitry
To check all the internal circuits in the RT are working correctly and the
navigation computer has booted correctly, use the following procedure:
1. Connect power to the system, connect the system to a laptop computer and
run the visual display software (NAVdisplay).
2. Use Table 33, below, to check the status fields are changing.
Table 29. Status field checks
IMU packets 100 per second or 250 per second, depending on product model.
GPS packets Between 2 and 20 per second (depending on system).
GPS2 packets
1
Between 2 and 20 per second (depending on system).
1
The GPS2 related fields will only increase for dual antenna systems.
These checks will ensure the signals from the GNSS and from the inertial sensors are
being correctly received at the navigation computer.
Field Increment rate
GPS chars skipped Not changing (but not necessarily zero).
IMU chars skipped Not changing (but not necessarily zero).
GPS2 char skipped
1
Not changing (but not necessarily zero).
