If you’ve ever used GPS in your car, you know it provides basic directions with around 5-10 meters of accuracy. While this works for everyday navigation, it’s not precise enough for the future of the automotive world, especially for autonomous driving or advanced fleet management. That’s where high-precision GNSS, combined with RTK (Real-Time Kinematic) correction data, steps in. Together, they bring accuracy down to the centimeter level, transforming how vehicles operate and how you manage them.
Imagine you’re in a self-driving car. The vehicle needs to know exactly where it is on the road—down to the centimeter. Without that precision, it could swerve out of its lane or miss obstacles. GNSS combined with RTK corrections enables the car can navigate centimeter accuracy. This technology isn’t just for futuristic autonomous cars; it’s already in use, ensuring safer, more reliable autonomous driving experiences.
To meet the needs of automotive market, we showcase our products suited for vehicle use cases:
To get centimeter-accurate location, your GNSS receiver needs correction data. For vehicles that traverse large distances or multiple countries, relying on a base station for RTK corrections is impractical due to distance limitations—typically less than 35 km. Using local NTRIP correction services is effective within a single country, but traveling across borders can lead to issues, such as having to reconnect to different local RTK service providers and dealing with changes in coordinate systems.
To simplify this, it is better to choose a global correction service provider which use global coordinate system and offers consistent quality of service over large areas, even in remote places without internet. Our ArduSimple Starter Kits include a free trial of global augmentation services to get you set up quickly.
If you’re a fleet manager accustomed to 5-15 meter GPS accuracy, ArduSimple can enhance this to sub-meter or centimeter levels. This high accuracy allows to optimize routes, reduce fuel costs, and ensure your drivers and assets are managed efficiently. Whether you’re overseeing truck tracking, car-sharing services, public transport, or warehouse forklifts management, we can help to enhance the operation’s productivity and reliability. See how ArduSimple RTK boards and Wialon cloud service enhance tracking, from public transport to deliveries.
V2X technology allows vehicles to communicate with each other and with surrounding infrastructure like traffic lights and road signs. This communication is powered by GNSS/RTK, which provides precise location data. RTK-powered vehicles can exchange information about their position, speed, and direction, helping to prevent accidents by alerting nearby vehicles to potential collisions.
Precise car data helps train drivers for safer journeys. Centimeter-level GNSS accuracy allows monitoring of speeding, harsh braking, and other behaviors. This data supports driver coaching programs that improve road safety. Combining GNSS and accelerometers provides reliable detection of harsh driving events like rapid acceleration and cornering. It also helps reduce risks like cargo damage from sudden maneuvers. A fleet safety program using this data simplifies coaching and ensures safer driving practices.
