Abstract
As Mission Extension Vehicles (MEVs), Mission Robotic Vehicles (MRVs), and other on-orbit servicing vehicles in Geostationary Orbit (GEO) emerge as innovative solutions for both military and civilian space sectors, it is imperative to understand their maneuverability, capabilities, limitations, and risks. This research developed theoretical models using Model Based Systems Engineering (MBSE) and Systems Modeling Language (SysML) to analyze on-orbit servicing vehicle trajectories, docking protocols, and servicing interactions with client satellites. This study aimed to conceptualize potential threats by modeling various mission profiles and use cases through built-in behaviors and patterns for cooperative and non-cooperative client satellites. Risks associated with exploitations for co-orbital anti-satellite (ASAT) operations were assessed, leading to recommendations for future modeling to support defensive countermeasure strategies. Benefits include optimized space asset security, operational efficiency, and strategic planning amidst a complex threat landscape. The MBSE model analysis aimed to balance on-orbit servicing mission capabilities with protecting high-value space assets in a contested GEO environment that supports essential national security functions. This research endeavors to further the academic body of knowledge on sustaining satellites in GEO through on-orbit servicing.
