Navigation Service Performance Assessment for Cislunar Transfer Spacecraft Using BDS-3 and DRO/NRHO-Augmented Constellations

This study assesses the navigation-service availability and observation geometry of a layered cislunar architecture using the BeiDou Navigation Satellite System Phase III (BDS-3) as the Earth-side primary source and distant retrograde orbit (DRO) and near-rectilinear halo orbit (NRHO) nodes as lunar-side augmentation s...

Preliminary analysis for the joint autonomous orbit determination of the BDS-3 MEO satellites and lunar ELFO satellites based on inter-satellite links

A fundamental limitation of Autonomous Orbit Determination (AOD) for Global Navigation Satellite Systems (GNSS) constellations using Inter-Satellite Links (ISLs) is the inherent unobservability of the overall rotational bias, leading to continuous degradation of orbit determination accuracy. To address this limitation,...
