世界上以发射卫星为主的航天发射市场业已形成,并且竞争激烈。目前,发射和经营通信卫星是航天领域中最实用、盈利最高的产业。一九八五年到一九九五年十年中,国际上将发射200颗商用通信卫星,每颗发射费用约三千万美元,总耗资约六十亿美元。据欧洲航天局预测,目前不具备发射能力的国家仍有100多个卫星等待委托发射,发射这些卫星的平均年营业额可达十四亿美元。如 The world’s space launch market dominated by launch satellites has been formed and is highly competitive. At present, launching and operating communications satellites are the most practical and profitable industries in the aerospace field. From 1985 to the mid-decade of 1995, 200 commercial communication satellites will be launched internationally, each with a launch cost of approximately US$30 million and a total cost of approximately US$6 billion. According to the European Space Agency’s prediction, there are still more than 100 satellites waiting for commissioned launches in countries that do not have launch capabilities. The average annual turnover of launching these satellites can reach US$1.4 billion. Such as
