一、粗码和细分码的联合测角1.粗码编码式太阳敏感器已广泛应用于卫星姿态测量中。其原理是太阳光线通过一条窄缝(称作前缝)射到有透明及不透明区的光刻码盘图案上,由其下面的太阳电池接受信号,再把信号处理成反映入射光线角度α的二进制数码。在视场F一定的条件下,码盘的分辨率αc取决于码盘码道的数量n,其关系是: First, the crude and subdivision code joint angle measurement 1. Coarse encoded sun sensor has been widely used in satellite attitude measurement. The principle is that the sun’s rays pass through a narrow slit (called the front slit) onto a pattern of opaque discs with transparent and opaque areas, receive signals from the solar cells underneath, and process the signals to reflect the angle α of the incident light Binary code. In the F field of view certain conditions, the codec resolution αc depends on the code track number n, the relationship is:
