Error Analysis of Inter-satellite Pointing of LEO Constellation Based on Satellite-borne GNSS Signal Receivers
(0) With the advent of micro-electro-mechanical systems, advanced materials, and integrated circuits and systems, the micro-satellites operated at low orbits have experienced rapid progress over the past decades, and a number of low earth orbit (LEO) satellite constellations are established to tackle wide-coverage high-resolution reconnaissance, communications, and navigation enhancement. Inter-satellite links (ISLs) serve as the infrastructure for LEO satellite constellation. In this paper we make use of the orbital information offered by the satellite-borne global navigation satellite system (GNSS) receiver, and propose a robust beam pointing calculation scheme. Moreover, the effect of receiver error on the inter-satellite pointing accuracy is evaluated. Simulation results reveals that beam pointing error caused by navigation receiver is at the order of 10-5, demonstrating the reliability of the proposed scheme for practical application.
