There is ever growing demand for satellite constellations that perform globalpositioning, remote sensing, earth-imaging and relay communication. In thesehighly prized orbits, there are many obsolete and abandoned satellites andcomponents strewn posing ever-growing logistical challenges. This increaseddemand for satellite constellations pose challenges for space trafficmanagement, where there is growing need to identify the risks probabilities andif possible mitigate them. These abandoned satellites and space debris maybeeconomically valuable orbital real-estate and resources that can be reused,repaired or upgraded for future use. On-orbit capture and servicing of asatellite requires satellite rendezvous, docking and repair, removal andreplacement of components. Launching a big spacecraft that perform satellitesservicing is one credible approach for servicing and maintainingnext-generation constellations. By accessing abandoned satellites and spacedebris, there is an inherent heightened risk of damage to a servicingspacecraft. Under these scenarios, sending multiple, small-robots with eachrobot specialized in a specific task is a credible alternative, as the systemis simple and cost-effective and where loss of one or more of robot does notend the mission. Eliminating the need for a large spacecraft or positioning thelarge spacecraft at safe distance to provide position, navigation and trackingsupport simplifies the system and enable the approach to be extensible with thelatest ground-based sensing technology. In this work, we analyze thefeasibility of sending multiple, decentralized robots that can workcooperatively to perform capture of the target satellite as first steps toon-orbit satellite servicing.
