Method of radio wave refraction error correction based on 0 deg and its nearby elevation angles

This paper analyzed the relationship between satellite elevation angle with difference SNR( signal to noise ratio) of BDS( Bei Dou Satellite Navigation System) different orbital satellite.

Control and test of elevation angle for dual-axis tracking system of horizon coordinates

This paper derives a set of differential equations which mustbe satisfied by the velocity elevation angle and velocity azimuth angle forsounding rocket. Under some approximation assumptions,the effects of thewind on the sounding rocket trajectory are analyzed.
