Performance Evaluation Experiment of High Power Transponder

摘要

Experimental telecommunications equipment of the Ka and S band was installed in Engineering Test Satellite Ⅷ (ETS-Ⅷ: KIKU No.8) launched in December, 2006. To investigate the secular distortion of this experimental telecommunications equipment, five times performance evaluation experiment was done. This experiment result represents an evaluation for the secular distortion of the equipment equipped to the satellite on the orbit, and it becomes a help in designing and production of the equipment installed to the satellite in the future.
