In the context of space situational awareness, orbit determination and maneuver detection pose considerable challenges given ever increasing number noncooperative satellites that perform unspecified maneuvers at unknown epochs. A new metric is proposed for here, based on measurements from a single surveillance radar. Data radar track are leveraged to derive this metric; it can flag occurrence since last time satellite was observed. scenarios considered in work, main challenge having just few...
In the domain of Space Situational Awareness (SSA), challenges pertaining to orbit determination and catalog correlation are notably pronounced, partly attributable escalating presence non-cooperative satellites engaging in unspecified maneuvers at irregular intervals. This study introduces an initial methodology reliant upon data obtained from a single surveillance radar, such as Spanish Surveillance Tracking Radar (S3TSR). The need for fast algorithms within operational context is...
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, main starting assumption is that object under analysis has an orbit known with a sufficient degree precision. Based on precise (a posteriori) data, manoeuvre are presented; one based unscented Kalman filtering, whereas two others algorithms reachability state, which correlates its prediction set next track radar. The filtering...
