Possibility of Centimeter Positioning Accuracy with Ambiguity Resolution from Android GNSS Raw Measurements

[weisongwen]

In this research, we improve the partial ambiguity resolution strategy of LAMBDA for Android-based GNSS data. The results show that it is possible to fix the ambiguity in an open sky environment, and an accuracy of 1 and 2 centimeter on horizontal and vertical is achieved. However, when the data suffer from large cycle slip, it will be hard to fix the ambiguity and lead to a float solution with sub-meter to meter accuracy
