Latest Patents

One of his latest patents is focused on the automated detection and characterization of earth-orbiting satellite maneuvers. This innovative process validates measurement data that align with the current orbit or allowable maneuvers for Earth-orbiting satellites. The validated data can detect both large and small maneuvers, including those that may have been overlooked by standard validation processes. Large maneuvers may appear as trends in residuals above the noise threshold from multiple sensors, while small maneuvers may show deviations from the expected orbit. The maneuver estimation routines utilize an objective function that combines a residual fit to the current orbit and maneuver, ensuring consistency and penalizing unused validated data. This comprehensive approach enhances the accuracy of maneuver estimates as new measurement data is received.
