Abstract

To choose a appropriate communication antenna for efficient communication between aircraft and satellite, antenna switching algorithm based on floating-point arithmetic DSP-TMS320F28335 recommended, which uses the angle of the antenna between the antenna and the star as a switch basis. paper the structure and precision of the floating-point arithmetic and measures to enhance the accuracy and speed of calculation during the coordinate conversion process. By contrasting the DSP estimation results with STK software simulation results, the correctness of the method. The experiments show that the proposed algorithm can precisely, in real-time, reliably and st deal with the navigation information. The errors of the angle between the antenna and the star are less than 0.05 degree.

Key words： floating point operation; satellite communications; antenna swictching; STK
