Stady on correlation of the three frequencies'ambiguities
Guorong Yu · Gnss World of China · 2002
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.
