The ATIS2.0 HMD solution is the most accurate Head Tracking System (HTS) on the market for helicopter application.
Monocular symbology display
- Field of view: 25°
- Definition: 800 x 600
- High brightness and contrast
- Day & night symbology with standard NVG
- Flight symbology
- Customised symbology designed by pilots
The Head Tracking System (HTS) uses hybrid technology combining Optical measurement done by two cameras and GyroMEMs.
High precision cameras provide absolute optical localisation independantly with a precision up to 2 mrds.
The hybridised Line of sight calculation provide a high level of redundancy using 3 independent sources: 2 high precision cameras + 1 GyroMEMs
Using one fast inaccurate instrument (Gyros) and two accurate but slow sensors (Camera) to get fast & accurate head positions
Easily customized to any basic helmet, a second skin is added including:
- 15 Leds + optics set to form the patterns
- Power board to manage & protect leds
- Intelligent boards with gyro providing:
- Helmet angles rates
- Memory for gyros and patterns calibration
