The deep dielectric charging effect monitor(DDCEM)has been designed to study the internal charging effect by measuring the charging currents and potentials inside the spacecraft.It is equipped on three Chinese navigat...
The autonomous navigation of the spacecrafts in High Elliptic Orbit (HEO), Geostationary Earth Orbit (GEO) and Geostationary Transfer Orbit (GTO) based on Global Navigation Satellite System (GNSS) are considered feasi...
The three key orbit design technologies employed in the Chang’e 5 mission are identified and discussed in this paper:orbit design for lunar orbit rendezvous and docking,orbit design for precision lunar landing and in...

The aim of this paper is to evaluate the minimum flight time of a solar sail-based spacecraft towards Earth-synchronous(heliocentric)circular displaced orbits.These are special displaced non-Keplerian orbits character...
At 11:22 Beijing time on December20,2019,liftoff of a LM-4B launch vehicle took place at the Taiyuan Satellite Launch Center,deploying into orbit 9satellites,including the China-Brazil Earth resource satellite-04A(CBE...
This paper will present the results and analyses of a simulation to send a satellite from the Earth to Mars. We use Python to simulate the orbit of the rocket. Our goal is to find the least energy-cost trajectory, wit...
