Description: Chang E III in at 1:30 on December 2, 2013 successfully launched December 6 arrived in lunar orbit. Chang E III runs on the quality of the landing track ready for 2.4t, installed in the lower part of the main gear of the engine can produce 1500N to 7500N adjustable thrust, specific impulse (ie, per unit mass of propellant to produce thrust) to 2940m/s, the speed of adjustment to meet the control requirements. Attitude adjustment around the engine installed in the main gear after a given engine thrust direction, to achieve a variety of attitude adjustment control pulse can automatically through a combination of multiple engines. Scheduled landing Chang E III is 19.51W, 44.12N, altitude-2641m (see Annex 1).
Chang E III in the case of high-speed flight, to ensure accurate lunar soft landing in a predetermined area, the key issue is the landing track and control strategy design. The basic requirements for its landing orbit design: landing point in recent months to prepare the track for 1
