High precision inertial navigation pdf
WebAn Inertial Navigation System (INS) is a system that is used to compute relative position over time from rotation and acceleration information provided by an Inertial Measurement Unit (IMU). An INS uses the measurements from the IMU to provide position, velocity and attitude (roll, pitch and azimuth) calculations. WebJul 13, 2024 · Precise geolocalization is crucial for unmanned aerial vehicles (UAVs). However, most current deployed UAVs rely on the global navigation satellite systems (GNSS) or high precision inertial navigation systems (INS) for geolocalization. In this paper, we propose to use a lightweight visual-inertial system with a 2D georeference map to …
