The ATH ( Afficheur Tête Haute ) or HUD ( Head Up Display ) is one of the most important tool for the UAV pilot. The ATH system can be fully integrated in the pilot helmet or in the ground station. On the ATH, the GPS datas about the UAV flight are displayed in real time on the video sent by the on board camera. With the help of the ATH system, the UAV pilot is fully able to check the flight plan and/or to steer the UAV in flight. You will find below the ATH v2.3 currently under test in real UAV flights. This new version have been significantly improved compared to the previous version v2.1.
In this new version 2.3, I have added some improvements and features :
- The frames rate of the GPS datas have been increased to the max frames rate defined by the NMEA 0183 v3.0 protocol,
- the bearing to destination heading and the Cross-Track error have been added on the bottom line,
- the firmware code have been optimized and reduced in size.

Comments : I have already done a lot of training nav in real flight conditions with my ATH v2.3 and its works very well at this GPS data frames rate. The next step, currently under developpement and tests, is a full and integrated auto-pilot (with a telemetry to the ground station) which will be able to steer the UAV according to the flight plan stored in the onboard computer...
Stay tuned...
