    • A process for increasing the availability of a global navigation system that includes a plurality of spacecraft, each of which transmits information for determining the position of a terminal. From the plurality of spacecraft, a first subset, with at least one spacecraft, and a second subset are determined. the second subset being constituted by those spacecraft that are not included in the first subset. The integrity risk is determined for the information transmitted only by the second spacecraft. The first and the second subsets of spacecraft are determined such that the integrity risk, for information transmitted by the second subset spacecraft minimized relative to the integrity risk for information of all spacecraft included in the plurality of spacecraft.
    • 一种用于增加包括多个航天器的全球导航系统的可用性的过程,每个航天器都发送用于确定终端的位置的信息。 从多个航天器中确定具有至少一个航天器的第一子集和第二子集。 第二子集由那些不包括在第一子集中的那些航天器构成。 对于仅由第二航天器传送的信息确定完整性风险。 确定航天器的第一和第二子集,使得由第二子集航天器传输的信息相对于包括在多个航天器中的所有航天器的信息的完整性风险最小化的完整性风险。

    • Methods and apparatus for implementing a receiver autonomous integrity monitoring (RAIM) algorithm are provided. The RAIM algorithm is for determining an integrity risk in a global navigation satellite system (GNSS) by processing several ranging signals received from satellites of the GNSS. The algorithm involves determining several integrity risks at an alert limit for different fault conditions of the ranging signals, and determining an overall integrity risk at the alert limit from the determined several integrity risks.
    • 提供了一种用于实现接收机自主完整性监控(RAIM)算法的方法和装置。 RAIM算法用于通过处理从GNSS的卫星接收的多个测距信号来确定全球导航卫星系统(GNSS)中的完整性风险。 该算法涉及在测距信号的不同故障状况的警报极限下确定几个完整性风险,以及从确定的几个完整性风险确定警报极限处的整体完整性风险。
