Decoding Notes

 The QINSy driver only decodes the ranges in meters.

Database Setup

To decode the ranges, add a "Fixed Node" with the correct positions for each of the seabed transponder used in the LBL array to the QINSy Database. Add the "Surface navigation system" and set the appropriate driver and interfacing parameters. In the observations tab, add "Range" observations connecting the LBL transducer and each of the seabed transponders in the array. For the slot numbers, apply the following convention. The observation between the LBL transducer and the first transponder (location) in the array will get slot number '1', the observation between the LBL transducer and the second transponder will get slot number '2', etc.

To decode the pitch & roll, add a "Pitch, roll and heave sensor" and set the appropriate driver and interfacing parameters. The two observations are automatically added and connected to the system. Change parameters to match the rotation sign convention and measurement units of the format description.

To decode the course, add a "System" of type "Gyro" and add an "Observation" of type "Bearing, true".

To decode the depth , add an "Observation" of type "ROV Depth" to the "Surface navigation system".

To decode all five observations, make sure to select the same driver name and I/O parameters for all systems.
