Design and Simulation of Self-Adapting Anti-Interference Algorithm with Information Technology in Satellite Navigation

Abstract

Satellite navigation system has been widely used in various fields, because of the signal which is received on the ground is weak and the low ratio of signal to interference, the signal is susceptible to be interfered. The adaptive antenna system using power inversion algorithm with information technology is very suitable for the weak signal and strong interference. The paper presents a detailed analysis on the principle with information technology. By building the hardware circuit in the QuartusII, the self-adapting anti-interference system of power inversion algorithm with information technology which based on Linearly Constraint Minimum Variance (LCMV) criterion can be achieved. The correctness of the theoretical analysis and correctness of the design are verified by experiment, the requirements of satellite navigation receiver on the side of anti-interference has been also proved.

A Strap-Down Inertial Navigation/Spectrum Red-Shift/Star Sensor (SINS/SRS/SS) Autonomous Integrated System for Spacecraft Navigation

“…It is sensitive to external disturbances, since its navigation accuracy depends on the coverage area of ground stations and the propagation conditions of radio waves. The satellite navigation is an extension of the space-based radio navigation [ 5 , 6 ]. It is simple in implementation and highly accurate in positioning.…”
