Abstract: Smartphone positioning utilizing advanced GNSS technology is allowing unprecedented access for precise location services to the mass?market. With the access to raw GNSS measurement and the advent of GNSS receiver chips allowing multi? frequency signals and carrier?phase measurement on a number of Android phone models have provided ideal platforms to further investigate and improve smartphone positioning capability. The Google Smartphone Decimeter Challenge has provided a plethora of raw GNSS measurements and smartphone sensor output data sets with reference solutions. The paper focuses on the performance assessment of tightly coupled smartphone sensors with legacy and state space corrections which will be utilized for lane level navigation. A threshold of 3 m was adopted and the performance under different environments and processing modes was analyzed. Less than 69% of the traditional smartphone code?only SPP solution had a cross?track errors less than 3 metres while for RTK/IMU and PPP/IMU tightly coupled solutions, more than 95% epochs have cross?track errors less than 3 metres.
