Abstract
The antenna with polarization multiplexing was used to transmission high speed data on mid-high resolution LEO satellite. The computation precision of antenna pointing and tracing ground station shall be 0.1° (3σ) or less. This paper describes the design of algorithm. With GPS data and attitude on satellite, the difference vector between antenna and ground station is transformed from WGS-84 to antenna coordination through series coordinate transformation. The algorithm must be simplified for less time consuming. Meanwhile, pointing accuracy must be ensured. The assembling error of antenna is took into account to pointing earth station more exactly. The test results confirm that the algorithm meets the requirements for precision pointing and less time consuming.
