在太阳敏感器领域里一个突出的进展是利用星跟踪器技术制造小型全功能双轴太阳跟踪器。这种敏感器在110°视场范围内的双轴精度均达30″。它不必采用光谱平衡技术,就可标定到高精度。在MIL-STD-1553/1773数据总线上的数字输出通用性强,无需外部处理,无需用户另做接口。内部微处理器控制探测器,进行全部数据处理,直接输出双轴太阳角,并允许根据任务要求灵活编程。重要组件(如电子模块、探测器)在星跟踪器应用中已经通过空间环境考验。本文介绍这种新型敏感器的结构、特性和测试结果。这种太阳跟踪器为GN&C卫星工程师提供了一种方法,他们可以利用这种方法,以比常规太阳敏感器更轻的重量,更小的体积,来实现最好的多用途星跟踪器才能达到的姿态确定精度,而且组装和应用工程的工作量也最小。
A significant advance in the field of solar sensors is the use of star trackers to make small full-featured two-axis solar trackers. The sensor’s biaxial precision of 30 "over a 110 ° field of view is calibrated to high accuracy without the need for spectral balance. Digital Output Versatility on MIL-STD-1553/1773 Data Bus Strong, without external processing, without the user another interface. Internal microprocessor control detector, for all data processing, direct output biaxial solar angle, and allows flexible programming according to mission requirements. Important components (such as electronic modules, detectors) Has passed the space environment test in star tracker applications.This paper introduces the structure, characteristics and test results of this new type of sensor.This solar tracker provides a method for GN & C satellite engineers who can take advantage of this approach to Lighter weight and smaller volume than conventional sun sensors to achieve the attitude determination accuracy achieved by the best multipurpose star trackers and the least amount of assembly and application engineering effort.
