Abstract
In order to maintain the health and productivity of satellites, it is crucial to develop a system that can swiftly, accurately, and effectively reproduce the on-orbit workflow and behavior a spacecraft experiences. To achieve this, Planet created the Systems Validation (SysVal) ecosystem; originally developed to validate individual spacecraft subsystem design requirements, and has evolved to encompass satellite concept of operation workflows, innovating test processes while mitigating risks through the ability to rapidly mimic on-orbit activities in a lab environment. SysVal is a fully integrated hardware and software system composed of a ground station network and a mission operations center with multiple integrated satellites, developed in-house by Planet, to assist with operating its Dove constellation of Earth-imaging satellites. Planet’s implementation of agile aerospace has exposed the value of SysVal, which facilitates seamless transitions of operational improvements from development and experimentation to rapid productionalization by incorporating “Test-Like-You-Fly” principles. SysVal utilizes cloned instances of Planet’s operational mission control interfaces and data storage platforms along with fully integrated flight capable satellite hardware, the same build that is flown in space, to test software upgrades before they are deployed on-orbit, reproduce on-orbit issues on the ground, replicate continuous “Day in the Life'' satellite operations, examine changes with potential operational impacts, while being easily managed remotely by a distributed team. System autonomy is a principal component of SysVal to alleviate human-in-the-loop decision making, maintenance and resources, and is utilized for quick snapshots of the testbed states, software deploys to match the lab environment to the production environment, automated flashing of lab satellite onboard software images to match on-orbit satellites, as well as autonomous analysis of system-level metrics and daily testbed testing with operator notification. This paper describes the SysVal system utilized by Planet and the latest automations integrated into the ecosystem that assist with the testing and development of operating the world’s largest Earth Observation satellite constellation.
