We describe our Lunar Navigation Satellite System (LNSS) that was designed to provide the
PNT service at the Lunar South Pole region. Our LNSS is composed of eight satellites …

This paper presents a solution for autonomous orbit determination and time synchronization
of spacecraft in Halo orbits around Lagrange points using inter-satellite links. Lagrange …

Numerous lunar missions are planned for the next decade and the current deep space
tracking system could not be sufficient to support all of them, since it has inherent limits in …

Earth-Moon libration point navigation constellation has a merit of fully covering the cislunar
