To solve the problem of location service interruption that is easily caused by incomplete
visual satellite environments such as occlusion, urban blocks and mountains, we propose …

Satellite constellations can provide communication and navigation services to support future
lunar missions, and are attracting growing interest from both the scientific community and …

Due to the non-spherical perturbation of the Moon, the lifetime of ultra low-altitude Lunar
spacecraft may be quite short. In this paper, we analyze the lifetime of about 50 km-altitude …

Aiming to establish a long-term presence on the Moon, interest in new and robust
communication and navigation capabilities on the lunar surface is greater than ever before …

In this study, dual-satellite lunar global navigation systems that consist of a constellation of
two navigation satellites providing geo-spatial positioning on the lunar surface were …

Aiming to provide navigational framework to upcoming early lunar exploration missions by
lunar rovers, interests in robust and low-cost global satellite navigation systems (GNSS) …
