项目摘要

This research has promoted the ongoing development of a balloon-borne telescope system for remote sensing of planetary atmospheres and plasmas. In this system, a Schmidt-Cassegrain telescope with a 300-mm clear aperture is mounted on a gondola whose attitude is controlled by control moment gyros, an active decoupling motor, and a Sun sensor. The gondola can float in the stratosphere for periods in excess of 1 week. A pointing stability of 10 arcsec/sec will be achieved via the cooperative operation of the following three-stage pointing devices: a gondola-attitude control system, two-axis telescope gimbals for coarse guiding, and a tip/tilt mirror mount for guiding error correction. The tip/tilt mirror is controlled by a real-time correction signal from a position-sensitive photomultiplier tube. Video images of an object in near-infrared and ultraviolet are obtained by analog and digital CCD video cameras, respectively. Power is supplied by solar cell panels and Ni-MH batteries, of which low temperature characteristics have been tested. A pressurized cell contains two PCs, DC/DC converters, pre-amplifiers and a high-voltage power supply for a tip/tilt mirror mount. System performance under a low-temperature and low-pressure condition has been confirmed by a thermal vacuum test. ESRANGE in Kiruna, Sweden was investigated for a candidate launch site of a future experiment in the Arctic. The first target for the system is Venus. Wind vectors in the Venusian upper atmosphere will be derived from the tracking of cloud patterns observed in the ultraviolet and near-infrared regions. An experiment designed to test the system performance is scheduled to take place in Japan during June 2007, and a long-duration flight in the Arctic is scheduled for 2008.

这项研究促进了用于遥感行星大气和等离子体的气球载望远镜系统的持续发展。在该系统中，具有300毫米通光孔径的施密特-卡塞格林望远镜安装在吊舱上，吊舱的姿态由控制力矩陀螺仪、主动解耦电机和太阳传感器控制。缆车可以在平流层漂浮超过 1 周。通过以下三级指向设备的协作操作，将实现 10 角秒/秒的指向稳定性：吊舱姿态控制系统、用于粗略引导的两轴望远镜万向节以及用于引导误差的倾斜镜安装座更正。偏摆镜由来自位置敏感光电倍增管的实时校正信号控制。近红外和紫外物体的视频图像分别通过模拟和数字CCD摄像机获得。电源由太阳能电池板和镍氢电池提供，其低温特性已经过测试。加压室包含两台 PC、DC/DC 转换器、前置放大器和用于倾斜/倾斜镜安装座的高压电源。系统在低温低压条件下的性能已通过热真空测试得到证实。瑞典基律纳的 ESRANGE 正在接受调查，寻找未来北极实验的候选发射场。该系统的第一个目标是金星。金星高层大气中的风矢量将通过跟踪在紫外线和近红外区域观察到的云图案而得出。一项旨在测试该系统性能的实验计划于 2007 年 6 月在日本进行，并计划于 2008 年在北极进行一次长期飞行。
