摘要
本文提出一种类似于Ｉｎｔｅｒｎｅｔ域名服务的互联网可修复分级密钥分配协议，并给出了可行的泄漏密钥替换方法和密钥分配协议的设计原则，此外还发现纠正了［７］中的一个重要错误。
This paper proves theoretically that GDOP decreases as the number of satellite increases and proposes two recurrence algorithms for calculating the GDOP and positioning solution.These algorithms not only can recursively calculate the GDOP and positioning solution at the same time,but also is very flexible in obtaining the best four satellite positioning solution,the best five satellite positioning solution and the all visible satellite positioning solution according to given requirements.Since the algorithms does not involve the multiplication and inverse of matrix,a fewer calculations are needed.
