The next frontier of autonomous navigation for UAVs in GPS-denied environments requires hybrid and resilient solutions that overcome the drift problem of the Inertial Navigation System INS. Drift in INS is one of the main challenges for military drones because accumulated errors in gyroscopes and accelerometers generate position drift over time, compromising accuracy in critical missions and operations in GPS-denied spaces.
INS offers continuous position and orientation estimates, but its dead reckoning nature causes drift due to biases, noise, and thermal variations. For military missions where accuracy and safety are essential, relying solely on INS is not viable. This is where other complementary technologies such as SLAM, Optical Flow, and LIDAR come in, which can correct drift and provide redundancy.
SLAM enables mapping the environment and localizing simultaneously using cameras or LIDAR, being ideal for urban and complex environments. Optical Flow provides relative motion estimates based on visual patterns, useful at low altitude and in conditions where LIDAR is not practical. LIDAR provides high-resolution three-dimensional point clouds that enable precise reconstructions and obstacle detection. Each technology has advantages and limitations, which is why sensor fusion is key.
The hybrid approach combines INS, SLAM, Optical Flow, and LIDAR through probabilistic filters, multi-sensor fusion algorithms, and machine learning models to correct errors and detect failures. By integrating visual inertial odometry with LIDAR SLAM and neural networks for feature recognition and loop closure, robust navigation in GPS-denied environments is achieved. This architecture adds redundancy, improves fault tolerance, and enables prolonged operations without satellite updates.
