Dead Reckoning (DR)
Dead Reckoning (DR) is an inertial navigation localization algorithm based on multi-sensor data processing. It can utilize signals from various sensors such as GNSS, gyroscope, accelerometer, vehicle speed, and forward/backward motion status to achieve accurate positioning, especially in complex scenarios like tunnels and viaducts.
Capabilities and Advantages
- In environments with weak GNSS signals, it can still provide accurate location information relying on signals from sensors like gyroscope and accelerometer
- It supports self-correction for fewer cumulative errors
- It provides support for car manufacturers to acquire CarPlay certification
