Hy-BIRD

Ascension Technologies Corporation discontinued the production of the Flock of Birds. Replacement products are the 3D Guidance trackSTAR and driveBAY.

Hy-BIRD fuses optical and inertial technologies into one compact tracking solution. Its primary optical technology outputs highly accurate, fast tracking data. A fully integrated inertial tracker seamlessly continues tracking whenever the optical scanner is blocked or its field of view exceeded.

  • Fused data streams for flawless 360° tracking
  • Wide operational temperature range for inertial sensors
  • High speed tracking with minimal lag
  • Robust inertial sensor with embedded microprocessor
FEATURES & BENEFITS
Critical Features Key Benefits
240 optical measurements/second / 70-75 measurements/second in hybrid mode Fast updates with no discernable lag
Full 360° coverage no FOV limits
IR laser scanning technology with temperature compensated, calibrated inertial sensors Accurate, undistorted tracking in fixed, motion-based and mobile environments
Built-in optical correction for inertial drift Constant data flow without jumps or interruptions
Small footprint for emitter and detectors Easy set-up with minimal impact on cockpit/vehicle real-estate
Fast, one-time calibration for misalignments Flexible placement of optical and inertial sensors on helmet
COMPONENTS
Ascension Hy-BIRD

Hy-BIRD is composed of an optical scanning unit with embedded electronics (above) and two head-mounted sensors - optical and inertial. The optical sensor can be seen in the right foreground. Optical and inertial data streams are fused and transmitted to a host computer via a USB serial adapter.
