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.

这项研究促进了气球传播望远镜系统的持续开发，用于遥感行星气氛和等离子体。在此系统中，将带有300毫米透明光圈的Schmidt-Cassegrain望远镜安装在吊船上，其态度由控制矩陀螺仪，主动解耦电动机和一个太阳传感器控制。缆车可以在平流层中漂浮超过1周的时间。通过以下三阶段指向设备的合作操作，将实现10个ArcSec/sec的指向稳定性：弓形齿状控制系统，用于粗制引导的两轴望远镜的望远镜的望远镜和用于指导误差的尖端/倾斜镜安装座。尖端/倾斜镜由来自位置敏感的光电倍增管的实时校正信号控制。分别通过模拟和数字CCD摄像机获得近红外和紫外线物体的视频图像。电源由太阳能电池板和Ni-MH电池提供，其中已经测试了低温特性。一个加压电池包含两个PC，即DC/DC转换器，预放大器和一个用于尖端/倾斜镜安装的高压电源。通过热真空测试证实了低温和低压条件下的系统性能。瑞典基鲁纳的Esrange进行了调查，以在北极进行未来实验的候选发射场。该系统的第一个目标是金星。金星上层大气中的风向量将源自在紫外线和近红外区域中观察到的云图案的跟踪。一项旨在测试系统性能的实验计划于2007年6月在日本进行，并计划在2008年进行北极的长期飞行。
