The GPS Heading Sensor evaluation system uses the Crescent © GPS heading reference engine interfaced with an isolated dc/dc power converter and dual port RS232 driver. The user interface also provides filtered and current limited antenna power for the GPS antennas used to derive heading from the GPS satellites. By simultaneous and coincident constellation tracking, two receivers with common processing derive the local GPS position, differential GPS corrections and heading with respect to true (geographic) north. By using high precision differential carrier phase measurements heading accuracies to better than 0.5 degrees can be achieved with antennas separated on a 1 meter base line.
For dynamic applications tilt and turn rate sensing (gyro) aiding is included, configured by user commands.
