Design and Implementation of a High-Accuracy Positioning System Using RTK on Smartphones (2002.05857v1)

Abstract: In recent years, with the development of the Global Navigation Satellite System (GNSS), the satellite navigation technology has played a crucial role in smartphone navigation. To solve the problem of the low positioning accuracy in the smartphones based on GNSS, this paper proposes to apply real-time dynamic carrier phase difference technique (RTK) in the smartphones, and a real-time positioning system for smartphones based on RTK is implemented. This paper presents the implementation and experimental results of this system. This system is mainly composed of the GNSS reference station, the NTRIP system and the smartphones. The experimental results show that the system effectively improves the positioning accuracy of smartphones
