跟踪仪

As one of the most often used mountings, the altazimuth mounting satellite tracker has a blind area near the zenith because of the very high azimuth angular velocity, as a result, discontinuous observing data are caused. As for those fast flying satellites, this kind of blind area is very significant because it causes difficulties in precisely determining the satellites' orbits.

作为最常用的一种机架，采用地平式机架的人卫跟踪仪在观测天顶附近区域的目标时，由于方位转速过大而不能连续观测，存在一个固有的天顶盲区，特别是对飞行速度较快的近地卫星，这个盲区的影响是相当大的。

We analyzed and proved that this kind of mounting can cover all useful sky area and has much lower and smoother angular velocity and acceleration than the altazimuth one. IN THIS PAPER WE ALSO DISCUSSED THE RELATIONSHIP BETWEEN TWO MOST OFTEN USED ALT-ALT coordinate systems (SN-ALT-ALT, EW-ALT-ALT coordinate system) and the sidereal hour-angle coordinate system, the horizon coordinate system.

本文推导了ALT-ALT跟踪机架光电人卫跟踪仪原理，分析证明了它在要求的跟踪区域内不存在观测盲区，对同一目标的跟踪角速度和角加速度比地平式机架跟踪仪小且平滑，可实现全天覆盖。
