Multi-GNSS precise point positioning with next-generation smartphone measurements

ABSTRACT

This study evaluates the feasibility of achieving improved positioning accuracy with raw GNSS measurements from recently released smartphones. Using Precise Point Positioning (PPP) as the processing mode, positioning accuracy of selected newly available devices are analyzed. These devices include Xiaomi Mi8, Google Pixel 3, Huawei Mate 20 and Samsung Galaxy S9. The key research questions to be answered are: (1) Given the hardware limitations, what PPP processing changes can be implemented to make use of the raw measurements? (2) What is the best performance that can be achieved with multi-GNSS PPP given the usage of the smartphones by the user?
