The Orbit Analysis System (OAS) is a generic mission operations software tool built to perform end-to-end activities necessary for flight dynamics operations. There are three core modules in the OAS software: orbit determination, manoeuvre planning, and product generation. A legacy version of OAS has been serving flight operations for multiple missions since 2003 and recent developments include a robust manoeuvre planning module to account for advances in propulsion technology such as electric low-thrust propulsion. A dynamic manoeuvre optimization algorithm has been developed to ensure mission targets are achieved at a minimum propulsion cost and with a minimum outage for the customer.

Developed to be highly configurable, the OAS enables administrators’ easy manipulation of system definitions, mission parameters and workflow variables for the various needs of the user. Coupled with advances in infrastructure technology, such as Virtual Machines (VM) and containerization, new customers can receive an operational system baseline for their mission with minimal additional effort. The system can be integrated into existing customer architecture or delivered as a larger mission-critical solution. Changes in mission phases, operating conditions, or alert thresholds are handled easily by modifying the system configuration. Dual implementations allow for parallel testing of new features or configuration changes for rapid operational deployment. Constellation applications are unlocked by handling multiple assets while maintaining performant custody operations such as orbit determination and look-ahead predictions. Automated notifications within the lights-out environment ensures minimal customer costs while allowing for necessary operational responses when needed.

This paper outlines the OAS system framework and presents the core modules detailed descriptions. A technology roadmap for further system efficiencies and cost-reductions is also presented.
