空中观测设备(Airoscope)是为观测红外波段的星体而设计的球载望远镜系统。望远镜用陀螺稳定,其定向指令来自电视、星体跟踪器或地面站。由一对磁通门伺服罗盘作初始定向后,电视系统再进行搜索扫描和准确的截获。指挥和控制是借助256路指令的超高频线路实现的。科学和工程数据由“L”波段窄带调频遥测信号送至地面站。地面站显示飞行期间发回的所有的科学和工程数据,以及工作状况。并记录指令和遥测数据,以便详细分析。望远镜由直径71厘米的主镜和Dallkirkham光学系统组成。主镜光束由摆动的次镜按指令以11或25赫的频率自左或自右开始摆动来进行调制。位于望远镜焦平面上多密度靶(multi-densitytarget)后面的调相管,提供准确的较准信号,并按指令调整次镜进行聚焦。对可见光目标定向精度为±10弧秒(均方根值)以内的星体跟踪器,可根据指令接入陀螺控制回路,以代替电视跟踪可见光目标。吊舱内主能源是银锌蓄电池组,额定寿命为80安培小时。
Airoscope is a ballistic telescope system designed to observe the infrared band of stars. The telescope is stabilized with a gyroscope and its directional commands come from a television, a star tracker or a ground station. By a pair of fluxgate servo compass for the initial orientation, the television system to search scan and accurate intercept. Command and control is accomplished with 256-way UHF lines. Scientific and engineering data is sent to the ground station from the “L” band narrowband FM telemetry. The ground station displays all scientific and engineering data sent back during the flight, as well as the status of work. And record instructions and telemetry data for detailed analysis. The telescope consists of a 71 cm diameter primary mirror and a Dallkirkham optics system. The primary mirror beam is modulated by the oscillating secondary mirror on command, swinging either left or right at 11 or 25 Hz. The phased tube behind the multi-density target on the focal plane of the telescope provides an accurate, accurate signal and focuses the secondary mirror as instructed. A stellar tracker with a directional target of ± 10 arcsec (root mean square) accuracy for visible light targets can be connected to the gyro control loop as instructed to replace the television with a visible light target. The main energy inside the pod is a silver-zinc battery pack with a rated life of 80 ampere hours.
