从铱星市场受挫看卫星移动通信的前景

Analysis of Indium Setbacks and Forecasts of Satellite Mobile Communications

铱星系统濒临破产的主要原因,一是手机生产缓慢、供货渠道不畅,造成延误;二是手机体积庞大、结构复杂,价格昂贵;三是通话费用高,各地价格差别大,且受到地面系统的有力挑战;四是市场前景认识不清,判断失误;五是业务开通之初掉话严重、数据传输速率低、服务性能尚欠火候。尽管如此,由于其具有极高的创新性、先进的技术、无与伦比的覆盖面等优势,在克服种种困难、进行适当调整后,铱星系统将同其他卫星系统形成既互相补充、又互相竞争的局面,前景仍是很光明的。

Indium company is on the verge of bankruptcy due to the following reasons: First, slow handset production and delivery; Second, large-size handsets with complex structure and high cost; Third, high tariff and threatened by the challenge from the terrestrial system; Fourth, misunderstanding and misjudgement of the market prospects; Fifth, severe call-drops, low data rate, and inadequate performance from the outset. In spite of that, with its innovativeness, high-tech nature and unrivaled coverage, Iridium will be able to overcome various difficulties and regain its momentum; complementing and competing with other satellite systems.
