Currently UAS rely 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.
