A heteroskedasticity and autocorrelation consistent test for process noise calibration of Kalman filters in multi-sensor orbit determination
Antonio Malaver, Jose M. Montilla, Rafael Vazquez
Process noise calibration is a central problem in sequential orbit determination. If the process noise covariance is too small the filter is overconfident, and if it is too large i…

Manoeuvre detection in Low Earth Orbit with Radar Data
Jose M. Montilla, Julio C. Sanchez, Rafael Vazquez +3
This work outlines and assesses several methods for the detection of manoeuvres in Low Earth Orbit (LEO) from surveillance radar data. To be able to detect manoeuvres, the main sta…
