Abstract:
This paper characterizes these SSA accuracy, timeliness, and safety degradations caused by maneuvers, maneuver uncertainties, and outdated orbit determination system inability to accommodate maneuvers in both Rendezvous and Proximity Operations (RPO) and normal spacecraft operations. Maneuvers (both shared and non-cooperative/unknown) and associated maneuver uncertainties are a leading cause of degradations in safety and SSA accuracy, timeliness. These degradations often render flight safety products insufficient to meet spacecraft operator needs in today's increasingly challenging environment. A holistic, collaborative, and technically advanced approach is needed to address these maneuver induced SSA degradations. Practical ways to accomplish this include (1) collaborative planned maneuver and observation sharing in a data lake model, (2) incorporation of commercial SSA observational data, (3) data sharing standards development and widespread adoption; (4) data fusion and improved analytics, and (5) orbit determination algorithms suited to rapid non-cooperative maneuver detection, characterization, calibration, and recovery. From a technical perspective, existing high Technical Readiness Level (TRL) SSA systems can help gather and maintain actionable SSA/SDA knowledge, allowing decisionmakers to mitigate SSA degradations caused by maneuvers and get the SSA data they need to make informed space safety and sustainability decisions
