Global Navigation Satellite Constellation Design Using Walker Constellation

Fuping Sun

Abstract

The effects of the orbital plane number,satellite number and orbital eccentricity on constellation capabilities are discussed.Through the comparative calculations on three kinds of configuration,six kinds of semi major axis and orbital inclination between 46°~66°,the original configurations are designed based on the constellation CV values in repeat period.Combined with the coverage capability,the most DOP value and precision usability,the global navigation satellite constellation using Walker-δ constellation is introduced.The method of strengthen the local navigation capability is discussed by adding the GEO satellite.
