IMU Assisted real time precise point positioning with smartphones

In May 2016, Google revealed that users would be able to access the raw global navigation satellite system (GNSS) measurements through a new API implemented on Android 7 or later versions. Afterward, many research have been conducting to investigate and to improve smartphone positioning. This project aims to improve the real-time precise point positioning (PPP) performance using smartphones, by utilizing the measurements from the inertial measurement units (IMU) embedded in the smartphones. The GNSS observations from Android smartphones can be utilized to estimate absolute position information. However, they might face challenges such as signal blockages or interference in urban environments, overpasses and similar scenarios. To address these issues, the inertial navigation system (INS) provides continuous position and velocity updates unaffected by external signals. In this research, the INS solution is integrated with the GNSS solution to improve the smartphone positioning in challenging environments. Different algorithms will be applied in this project to achieve the desired objectives. The potential benefits to Profound Positioning Inc. (PPI) through my internship can be substantial, primarily driven by my extensive expertise in navigation systems, smartphone positioning, and sensor fusion. My strong academic background and research experience in Geomatics Engineering, particularly in smartphone positioning using the PPP method, will give the company significant technical knowledge and a unique perspective in developing advanced navigation solutions employing the low-cost smartphone devices. It could also make the company stronger by improving its ability to design navigation solutions navigation in challenging environments and GNSS-degraded areas.
