The TRX NEON Navigation Engine implements dynamic mapping and calculates location within buildings and other structures without access to reliable GPS. The Navigation Engine intelligently fuses information from all available sensors - including accelerometer, gyroscope, altimeter, magnetic, ranging, and GPS – to map environments and deliver an accurate location.
The Navigation Engine continually analyzes and assesses all sensor data for quality and consistency. Poorly functioning or degraded sensors are isolated and de-emphasized or eliminated in the navigation solution. Received sensor information is then used to infer site maps, building features, and other landmarks (distinct building and transition features) dynamically as people move about an area or building. Information from multiple people moving about in the same building is merged to deliver crowd-sourced enhancements to inferred maps, delivering accurate features maps that enhance location estimates. Additional ranging information (e.g., from known beacons), if available, can also be used to constrain location results. Such ranging Information includes ranging between people operating close together and between a person and a fixed RF node if infrastructure is available.
Given known maps, feature or floor plan information, accuracy will be further increased as NEON will match location estimates and inferred maps and features to known floor plans and maps, and implement wall avoidance. User initialization and corrections, where available, are also incorporated into the NEON solution.
The unique and patented NEON Navigation Engine, along with APIs for integrating with third party platforms and applications, can be made available to deliver mapping and improved location indoors and in other environments without reliable GPS.
