Progressive Replacement Sequence Planning for Laser-Enhanced BeiDou Navigation Constellations
Huan Yan, Juan A. Fraire, Ziqi Yang +5
The early satellites of the third-generation BeiDou Navigation Satellite System (BDS-3) are approaching the end of their design lifetime, making progressive constellation replaceme…
Contact Plan Design For Optical Interplanetary Communications
Jason Gerard, Juan A. Fraire, Sandra Cespedes
Space exploration missions generate rapidly increasing volumes of scientific telemetry that far exceed the capacity of today's manually scheduled, RF-based deep-space infrastructur…
POMDP-Based Routing for DTNs with Partial Knowledge and Dependent Failures
Gregory F. Stock, Alexander Haberl, Juan A. Fraire +1
Routing in Delay-Tolerant Networks (DTNs) is inherently challenging due to sparse connectivity, long delays, and frequent disruptions. While Markov Decision Processes (MDPs) have b…
Modeling Pointing, Acquisition, and Tracking Delays in Free-Space Optical Satellite Networks
Jason Gerard, Juan A. Fraire, Sandra Céspedes
Free-space optical inter-satellite links (OISLs) enable high-capacity space communications but require precise Pointing, Acquisition, and Tracking (PAT) between links. Current sche…
Selected Results from the REDMARS2 Project: Recursive Delay-Tolerant Networking using Bundle-in-Bundle Encapsulation
Marius Feldmann, Tobias Nöthlich, Felix Walter +4
This whitepaper presents parts of the results of the REDMARS2 project conducted in 2021-2022, exploring the integration of Recursive Internetwork Architecture (RINA) concepts into…
Joint Contact Planning for Navigation and Communication in GNSS-Libration Point Systems
Huan Yan, Juan A. Fraire, Ziqi Yang +11
Deploying satellites at Earth-Moon Libration Points (LPs) addresses the inherent deep-space coverage gaps of low-altitude GNSS constellations. Integrating LP satellites with GNSS i…
