A Staring Tracking Measurement Method of Resident Space Objects Based on the Star Tacker

Photonics, 2023
Measuring resident space objects (RSOs) by star trackers has become a research hotspot in space situational awareness. However, the arc length measured by star trackers is too short to complete the high-precision orbit determination of the RSO.
