Real-time sub-meter location tracking is crucial for vehicle safety in transportation management, especially for large buses and dangerous goods vehicles, but many consumer level GNSS accuracy devices are just around 3-5 meters. This paper introduces a real-time array calibration (RAC) positioning technology, via road test comparison in different scenarios with other two terminals. Through the analysis of multiple indicators, it is found that the RAC terminal has better positioning stability than other terminals in different scenarios and can reach sub-meter accuracy. This technology can be used location based service (LBS) with sub-meter, and it will be widely applied to driver assistance system (DAS), unmanned aerial vehicle (UAV) navigation system and other fields.
