This study introduces a celestial positioning sensor, enhancing accuracy in cross-domain flight operations using calibration methods.
A celestial autonomous positioning sensor using a multi-spectral star sensor, dual-axis inclinometer, and precision clock, is introduced in this study. We propose a multi-spectral star detection scheme to resolve sky background variation challenges during cross-domain flight operations. Multiple coordinate systems are systematically linked to achieve autonomous positioning, with joint calibration methods used to quantify and correct inclinometer installation errors, which significantly improves cross-domain autonomous positioning accuracy, achieving 156.11 m (3 σ ) precision.
