Abstract

Abstract:

Low Earth Orbit (LEO) satellite navigation systems are critical for the positioning and navigation of Unmanned Aerial Vehicles (UAVs) in complex channel environments, where the calibration of dynamic parameters serves as a fundamental guarantee for system reliability. Considering the wide-ranging dynamic parameters characteristic of LEO satellite navigation systems, this study adopts a dynamic parameter calibration method based on the least squares algorithm. Simulation results demonstrate that, compared with traditional calibration methods, the least squares-based calibration method significantly reduces the uncertainty of calibration outcomes and enhances the reliability of UAV positioning results.

Key words: UAV positioning, LEO satellite navigation signal simulator, dynamic parameters, least squares method
