Overview
Position Integrity TerrAvoid is a high-performance standards-based software application designed to reduce Controlled Flight Into Terrain (CFIT) accidents and save lives. Developed under military contract and already a proven air safety asset to the military community, TerrAvoid provides a visual depiction of surrounding terrain using advanced high-resolution data.

Details
TerrAvoid was written for the Microsoft Windows family of operating systems, yet its terrain manipulation algorithms have been used by several aerospace and avionics manufactures in embedded avionics systems. The primary terrain algorithms are portable to virtually any platform and currently support high resolution military terrain data, but can be easily adapted to support lower resolution terrain data like Digital Elevation Models (DEM).

TerrAvoid constructs and updates a shaded relief map only the fly, changing its colors dynamically based on your relative position to the surrounding terrain, as determined by an attached GPS receiver. The look-ahead distance will provide at least eight minutes of terrain warning, an order of magnitude more than most commercial ground proximity warning systems (GPWS) available today.

TerrAvoid also provides the Flight Mode Checks and Warning Mode Checks specified by the Federal Aviation Administration for terrain avoidance systems. TerrAvoid can be configured to display this information simultaneously along side the map window.

Advanced Datasets
The Position Integrity development team is working in close proximity with NASA's Jet Propulsion Laboratory and will be the first to integrate the advanced terrain and obstacle datasets resulting from the 2000 Shuttle Radar Topography Mission (STRM). This new dataset will bring highly accurate terrain and obstacle information to the general public at resolutions that were previously only available to the military or classified government agencies.
