Abstract:	Recently, there has been a growing demand for high-precision smartphone positioning. GNSS positioning is typically the core of precise positioning algorithms in many applications. However, smartphone GNSS receivers suffer from the low availability of dual-frequency observations. Additionally, smartphones' low quality and noisy GNSS observations made their positioning solution vulnerable to cycle slip, multipath, and solution discontinuity. Therefore, GNSS needs to be aided by other sensors to assure the solution continuity and keep the accuracy within acceptable limits. This study develops a tightly-coupled integration of GNSS precise point positioning (PPP) and the reduced inertial sensor system (RISS) to provide a reliable positioning solution in challenging GNSS environments. The results showed that the developed PPP/RISS solution smoothed the spikes in the PPP solution where the cycle slips are detected. Additionally, the tightly-coupled integration improved the accuracy of the positioning solution.
