N2 - Low earth orbit (LEO) satellites have low orbit altitude, strong landing signal power, and strong anti-interference ability, which is an attractive way to provide available navigation and positioning services for GNSS-challenged environments. This work studies Iridium signals and establishes a mathematical model for Iridium Doppler positioning by extracting instantaneous Doppler information from iridium opportunity signals. Then, UWB is used to perform peer-to-peer ranging measurement and communication between agent nodes. Finally, a collaborative positioning technology based on Iridium/UWB is proposed. Simulation results show that compared with iridium satellite opportunity signal positioning, the proposed method can significantly improve the convergence speed and positioning accuracy of the algorithm.
