Drivers Manual

Tracs TDMA - 12


Driver to decode position or heading data which originates from the Thales Tracs TDMA system. Data may hold multiple positions and headings.

Tracs TDMA is a high speed, intelligent network radio datalink which operates in the VHF/UHF band to provide an addressable network datalink with integrated position reporting from an internal or external GPS receiver. 
It is primarily intended for vehicle and vessel tracking applications although it can be used for general data communication.

Decoding Notes

Heading is only decoded if a Tracs TDMA (Heading) driver is defined in Database Setup.

Database Setup

The Tracs TDMA driver can be used to obtain a position and/or a gyro reading. Select a different system with its own type for each one of the data types to be decoded. Be sure to define the same interfacing parameters, including driver description and COM port number and settings, for all of these systems.

To use the position, add a "Variable Node" for the antenna to the QINSy Database. Add a "System" of type "Position navigation system" and define the interfacing parameters. Select the satellite system and its datum. Select receiver position and enter receiver number. This number is used as a slot number to decode the correct position from the data message.

To use the gyro reading, add a "Variable Node" for the (gyro)compass to the QINSy Database (if it differs from the object's reference point). Add a "Observation" of type "Bearing, magnetic" or "Bearing, true" and select the appropriate unit. Select the (gyro)compass node as "At node" and the "Null node" as "To node". Add a new "System" of type "Gyro or compass" and define the I/O parameters. Connect the observation.

Enter the slot number corresponding to the heading you wish to decode from the data message.
