Smoothing-Based Relative Navigation and Coded Aperture Imaging
Project Description
This project will develop a time-windowed smoothing algorithm for estimation of the relative poses and velocities between multiple, small, and potentially differently instrumented spacecraft. The smoothing algorithm will obtain the most probable estimate of the relative states between the spacecraft by using all available sensor information. It will be portable between different satellite platforms with different onboard sensors, adaptable in the case that one or more satellites become inoperable, and tolerant to delayed measurements or measurements received at different frequencies. It will be matured from technology readiness level 3 to 6 using the SPHERES-VERTIGO microgravity test platform on the International Space Station.
More »Anticipated Benefits
This technology could help enable constellations of small spacecraft with less sophisticated instruments to fly in close formation by making better use of the available sensor information. For satellite servicing missions, this could be used to enhance the accuracy and precision with which relative pose and velocity estimation is performed, improving the probability of mission success. Inspection of space debris or defunct satellites prior to their deorbit or servicing is a potential commercial application of the proposed technology.
