Decoding Notes

Easting and Northing are converted to latitude and longitude.

Depth is decoded as negative height.

The RMS value is used for latitude/longitude/height SD.

Heading is decoded if a true bearing observation is connected.

Database Setup

To decode the position , add a "Variable Node" for the Sonardyne APS3 transducer to the Qinsy Database.

Add a "Position navigation system" and set the appropriate driver and interfacing parameters.
Select the survey datum for the (satellite) system and select the APS3 transducer node as receiver.

To decode the heading , add an "Observation" of type "Bearing, true", add a "System" of type "Gyro", select driver, and connect the heading observation.
To decode all observations, add both system types to the Qinsy database and make sure to select the same driver name and serial interfacing parameters for both systems.


Use an "Alert Display" to setup a "Position RMS outside limit" raw data alert to test the RMS value.
