Taking into account the observation efficiency, the attitude stability of the satellite and the ultra high requirements for thermal control accuracy, the L2 point halo orbit was selected as the mission orbit .

• The launch vehicle sends the satellite to a parking orbit with an orbital inclination of 28.5˚(200 km×35958 km) The satellite maneuvers and transfers to the mission orbit. 

• The satellite transfers to the halo mission orbit along the invariant flow pattern, which take about 117 days.
