小型军用对地观测卫星包括小型战术侦察与监测卫星、小型气象卫星和小型海洋学卫星等。以下将介绍上述卫星的一些方案、特点和关键技术。小型战术侦察与监测卫星美国海军根据1米分辨率的战术图像情报的要求,曾经提出一种战术成像卫星方案。在光电探测器方面,采用了一块四芯片拼接的4096×4096元的CCD面阵器件。这颗卫星采用三轴稳定,因受制于“侦察兵”火箭和航天飞机货舱中的“可脱离专用箱”的运载能力,设计上受到一定的限制。其成像数据将 Small military Earth observation satellites include small tactical reconnaissance and surveillance satellites, small meteorological satellites and small oceanographic satellites. The following will introduce some of the above satellites programs, features and key technologies. Small Tactical Reconnaissance and Surveillance Satellites The US Navy has proposed a tactical imaging satellite solution based on the tactical imagery intelligence of 1 meter resolution. In the photodetector, using a four-chip splicing 4096 × 4096 yuan CCD area array device. The satellite’s three-axis stability is limited in design due to its ability to be “detached from a dedicated box” in the “Scout” rocket and space shuttle’s hold. Its imaging data will be
