SPACECRAFT TRACKING IN DIFFERENT ORBITAL REGIMES

  • Title of project: SPACECRAFT TRACKING IN DIFFERENT ORBITAL REGIMES
  • Funding agency (Optional): DoD
  • Description: In the highly contested space environment, a pressing problem is the ability to identify and keep track of unknown/hostile resident space objects (RSO; man-made or natural). RSO stable tracking can be often prohibitive with intermittent observations from different acquisition-rate sensors (cameras, lidar, radar). The ability to reach consensus among asynchronous multiple sensors with continuous dynamics will enable unprecedented high accuracy RSO tracking and contribute to the most recent needs in the SSA domain. We will consider sensor dynamic models (measured data) for typical spacecraft systems as well as appropriate force models for different orbital regimes (i.e., prediction of motion in LEO vs GEO), and explore the ability of hybrid systems theory to achieve consensus among different, noisy and possibly stochastic sources of information. In addition to RSO stable tracking, we envision the ability to detect maneuvers, thanks to sudden disagreements after the high level model has converged to a consensus. Maneuvers will be interpreted as unexpected degradations of the model performances, leading to a need for model corrections that translate into control inputs to be estimated.
