Our client:
one of the most important and renowned testing centers in the world, a premium provider of a wide range of high-level testing and engineering services dedicated to the entire automotive industry
High speed is supported by RTK, which allows for centimeter-level precision of GPS coordinates.
This solution is also crucial in situations of potential collision between vehicles, especially when they are moving at high speed in the same lane. The application includes a function called “Collision Warning”, which calculates in real-time the distance and speed of vehicles traveling in the same lane. Based on this data, the app warns the driver of a possible impact with the vehicle ahead.
For this feature to be effective, it is essential that the GPS coordinates provided by the device are extremely precise, in order to detect with certainty that the vehicles are in the same lane. For this purpose, RTK (Real-Time Kinematics) technology is used, which ensures coordinate accuracy with a margin of error of just a few centimeters.
Need
Traffic Management System adapted to the circuit’s operational logic with:
- Live Data Map
- Alarm Management towards control center and other users for traffic events via SoS and PTT
- Text message exchange (control center and users)
- Asset management and OBU (on board unit) delivery and return flow
- Mobile Device Management
- RTK GPS that utilizes the client’s infrastructure to prevent possible accidents on secondary routes
Solution, how it works
Usually, the GPS position detected by a commercial device has a margin of error of 2-3 m, while with RTK detection, positioning accuracy can reach centimeter-level precision.
- A Base Station is positioned in the circuit, with known coordinates (calibrated with extreme precision), also called a reference station, which is able to receive satellite signals and calculate in real-time the errors caused by the atmosphere, imprecise orbital position of satellites, etc.
- An app is installed on smartphones that captures raw coordinates, also known as RAW, received from satellites and which can have significant errors (meters or tens of meters) due to atmospheric effects and other factors.
- Differential corrections transmitted by the base station are applied to these coordinates, with the final result of having a coordinate accurate to the centimeter.
