随着微电子技术和微机械技术的日新月异,国际上已兴起小卫星热。这种质量在500千克以下的小卫星,具有很强的星上处理和自主能力,可广泛用于商业通信、空间探测等,尤其在军事上大有前途。小卫星的军用特点与许多大中型卫星相比,小卫星有许多独特的军用特点:①可快速、机动发射。它可使用小型运载火箭通过铁路、公路机动发射或用飞机从空中发射。例如,用B-52机翼下携带的“飞马座”空射型火箭可根据需要随时发射400千克重的小卫星。军用小卫星所具有的这种机动发射能力使敌人很难掌握,故卫星的生存能力强。美国防部正研制几种移动式小卫星运载工具,以便战时可把各种独立的小卫星及其运载火箭装在塑料容器中随车运输,一旦需要便可随时随地立即升空。用“飞马座”火箭发射小卫星只需准备3天。②研制周期短、成本低、系
With the ever-changing micro-electronics and micro-mechanical technologies, there has been a rise in small satellite heat in the world. This small satellite, with a mass below 500 kg, has strong on-satellite processing and autonomous capabilities and can be widely used in commercial communications, space exploration and the like, and is especially promising in military affairs. Military characteristics of small satellites Compared with many large and medium satellites, small satellites have many unique military features: ① can be fast, mobile launch. It can be launched using small launch vehicles on railways, on road maneuvers or by air from airplanes. For example, “Pegasus” air-launched rockets carried under the wing of the B-52 can launch small 400-kg satellites at any time, as needed. Military mobile satellites have such a mobile launch capability makes it difficult for the enemy to master, so the viability of the satellite is strong. The United States Department of Defense is developing several mobile small satellite carriers to transport independent small satellites and their launch vehicles in plastic containers during wartime and to be ready for immediate launch whenever needed. Just use the “Pegasus” rocket to launch a small satellite for three days. ② short development cycle, low cost, Department
