Currently, UAS relies heavily on GPS, which can be unreliable in various settings including ‘urban canyons’. Live Maps: Air provides an infrastructure free alternative to Global Navigation Satellite Systems (GNSS), such as GPS.
LiveMaps: Air builds on our existing GPS-denied visual navigation system, which integrates passive sensors with camera data in real-time to make a robust and accurate determination of location relative to a given take-off location.
The technology takes the flexible ‘tile’ maps from this navigation system and aligns them with a map from another source to locate a UAS in real-time in global coordinates using only on-board passive sensors. This continuous reference back to the map corrects any accumulated errors and removes the need for loop closure, which is the usual approach in vision-based slam systems.
