Layered Inertial-Terrain-Visual Navigation for UAVs Under GNSS-Denied Conditions: A Case Study over the Tibetan Plateau
A UAV operating without GNSS faces unbounded inertial drift. A layered navigation architecture is evaluated in which terrain contour matching (TERCOM) provides periodic position corrections and satellite-image scene matching adds a condition-dependent precision layer. The architecture is examined through a single-traje...
