This paper proposes the differential positioning technique to reduce the Signal-In-Space
Range Error (SISRE) of LNSS satellites and the coordinate transformation errors from Earth …

This paper addresses the navigation problem for a moving object at the lunar South Pole
region using our Lunar Navigation Satellite System (LNSS). The LNSS is a satellite …

This paper evaluates a method to improve the accuracy of a lunar satellite-based navigation
system for two different localization techniques, the One-Way ranging and the Two-Way …

Measurement differencing with GPS is an important method to reduce shared error between
a user and a nearby reference station. It may also be crucial for position, navigation, and …

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 …

Nowadays, several space agencies are emphasizing the interest for the human return to the
Moon. This renaissance in lunar exploration involves both the public and private sectors and …

In view of the upcoming missions to obtain resources from the lunar surface, it is essential to
have highly-accurate navigation systems to locate surface vehicles in shadowed regions. In …

In this paper, our lunar communication and navigation system called the lunar navigation
satellite system (LNSS) is presented. The mission of the LNSS is to provide the …

Positioning of high-orbit spacecraft using the Global Navigation Satellite System (GNSS) is
an important expansion application of GNSS. With the introduction of GNSS such as Beidou …

A detailed analysis of the algorithm for precision lunar descent and landing navigation is
presented. A continuous-discrete dual-state extended Kalman filter is developed in which …
