摘要
作为GPS现代化的一部分,一个新的载波信号将用于民用,这一信号的频率为1176.45MHz。虽然可以合理地假设观测值间是不相关的,但是分析表明三个频率的模糊度是强相关的;而L1模糊度与宽巷模糊度Nw=N1—N2、Nwc=N2—Nc相关性很弱,三个频率观测方程联立解算时应选择L1模糊度与宽巷模糊度Nw、Nwc。
Upon completion of the GPS modernization, a new signal will be made available to the civilian community. This signal will have a frequency of 1176. 45MHz. So,more measurements can be made for positioning. Although these measurements could be treated as uncorrelated measurements , the ambiguities of these three frequencies are correlated. But the L1 ambiguity is weakly correlated with wide lane ambiguity.
