Design and in-orbit application of multi-head star sensor
2023 2nd International Conference on Image Processing and Media Computing (ICIPMC)(2023)
摘要
Star sensor is a widely used astrometric sensor, which is one of the important attitude sensors in spacecraft control systems. The multi-head star senor is the first sub-arc-second star sensor in-orbit. The key design and distinct characteristic are proposed, the consistency between orbit result and ground test is analyzed based on orbit and ground data. The result in orbit show that single head precision is higher than $1''$ (30), and the fusion accuracy based on multi-head is better than $0.6 ''$ $(3\sigma)$ the optical-axis angle error is lower than $2''$, the SEA(sun excluded angle) is better than 26°. The star sensor can be used to military remote sensing satellite, astro observation with high precision and space science platform.
