| 摘 要： | 阐述了基于CCD技术的星敏感器的工作原理，及其在航天定位中起到的作用，从而引出星敏感器的地面标定技术，这就需要用到恒星模拟器对星敏感器进行标定。针对恒星光源的两个基本参数，分别提出了恒星色温模拟方法和星等模拟方法，研究了星模拟器系统的具体实现，主要设计了电光源、波段光强控制器、星等控制器等。在实验室实现了整个系统的组装，搭建了控制和测试平台，并得出了实验结果。实验结果表明，本系统具有较高的可靠性，在峰值光谱范围为350 nm~950 nm的情况下，可模拟星等范围0~+6.5MI，可模拟星体等效黑体温度为：2 600 K、3 600 K、4 300 K、5 000 K、5 500 K、6 000 K、6 800 K、7 600 K、9 800 K，相对强度误差优于±0.10。

| Abstract: | The working principle of star sensor based on the charged coupled device (CCD) technology was explained, as well as its important role playing in space positioning. The star sensor was needed to be calibrated by the star simulator using the ground calibration technique. According to the two basic parameters of the stellar light source, the simulation methods of the color temperature and the magnitude were proposed respectively. The realization of the star simulator was studied, and the electric light source, waveband light intensity controller, magnitude controller were designed. The entire system was assembled in laboratory, and the controlling and testing platform was set up. The experiments were carried out and the obtained results show that this system has high reliability. In the peak spectral range of 350 nm~950 nm, it can simulate the magnitude in 0~+6.5MI and the equivalent blackbody temperatures of the star: 2 600 K, 3 600 K, 4 300 K, 5 000 K, 5 500 K, 6 000 K, 6 800 K, 7 600 K, 9 800 K, the relative intensity error is better than ±0.10. |
