Resumen
Close-to-reality vehicle movement trajectory data can be useful in many transport and geography studies when precise vehicle localization or timing is required in the application. Vehicle kinematic tracking by GPS (Global Positioning System) varies in the data accuracy depending on both the receiver capability and the tracking environment. Advanced positioning techniques offer possibilities to enhance the tracking data quality. In this paper, the high performance of multi-GNSS (multiple Global Navigation Satellite Systems) with Real-time Kinematic (RTK) solution was investigated aiming to pursue precise vehicle movement trajectory in an urban residential area of Australia. This study systematically compared vehicle kinematic recordings between different positioning solutions by multi-GNSS and GPS-only approaches. Different elevation cut-off angles ranging from 5 - 35° were applied to simulate the satellite availability under different sky view conditions. The results show that the multi-GNSS approach outperformed conventional GPS positioning in the satellite availability and the positioning accuracy. The 10 Hz RTK solution proved to generate optimal vehicle movement trajectories for driving behaviours assessment.
