Abstract
The feasibility of using satellite translator to realize multiple-station ranging in TT&C of spacecraft is analyzed . On basis of spread spectrum ranging principle,using communication translator that translates uplink ranging signals to downlink ranging signals to achieve distance-measuring for satellite is studied . Meanwhile,the key technology including communication link power allocation between engineering TT&C and application systemof satellite,calibration method and the principle of satellite ground measuring equipment is described . The rang-ing scheme can break through traditional multiple-station ranging method that is limited by the number of satel-lite transponders . The achievement of new multiple-station ranging technique can improve ranging precision of e-quipment and orbit precision of satellite,reduce the requirement of equipment′goniometer precision and measur-ing time,and control equipment resources tension situation,while the ranging method is a backup means for side tone ranging using satellite transponder .关键词
