Control Strategy of Lunar Lander-Relay Satellite Antenna Acquisition and Tracking for Chang’e-4 Lunar Exploration Mission

2020 15th IEEE Conference on Industrial Electronics and Applications (ICIEA), 2020
Chang’e-4 lunar lander and "Yutu-2" rover safely landed on the farside of the Moon on 3rd, Jan., 2019. It is the first unmanned spacecraft to softly land on the lunar farside and carried out in-situ and rover exploration there. However, the lunar farside

Laser Power Beaming for Lunar Polar Exploration

AIAA Propulsion and Energy 2020 Forum, 2020
Advances in laser technology now makes it reasonable to use a laser to beam power directly from a power source at the illuminated rim of the crater to a photovoltaic laser receiver on a rover exploring inside the permanently shadowed region. To move this

Planetary Rover Simulation for Lunar Exploration Missions

IEEE Aerospace Conference, 2019
When planning planetary rover missions it is useful to develop intuition and skills driving in, quite literally, alien environments before incurring the cost of reaching said locales.

Design and analysis of novel Ka band NOMA uplink relay system for Lunar farside exploration

China Communications, 2020
This paper proposes a novel Ka band non-orthogonal multiple access (NOMA) uplink relay system for Lunar farside exploration, where a satellite relay node with the help of NOMA scheme, amplifies and forwards the signal from the Earth Base Station (EBS) to
