BGC-Nav: Cross-Altitude Multi-UAV Collaborative Navigation
Overview
BGC-Nav is a training-free framework for cross-altitude multi-UAV navigation, using belief-guided coupling to enhance aerial search-and-rescue operations. High-altitude UAVs maintain global belief memory, while low-altitude agents use local memory and advisory biases for decision-making, showing superior performance in experiments on ESARBench.

This research presents BGC-Nav, a training-free framework for cross-altitude multi-UAV collaborative navigation. It addresses challenges in aerial search-and-rescue by using belief-guided coupling to enable robust navigation. The high-altitude UAV maintains a global belief memory, while the low-altitude agent uses local memory and advisory biases for decision-making. Experiments on ESARBench show superior performance over existing methods.
