Dead Reckoning Technology

Currently, vehicles are usually positioned using the Global Positioning System (GPS/GNSS)
However, in practical applications, GNSS satellite signals are not completely reliable under high buildings, overpasses, basement parking lots, tunnels, dense trees and other sheltered environment which can reduce the positioning accuracy. Therefore, if you want to improve the accuracy of navigation, Dead Reckoning navigation becomes necessary.

Dead Reckoning Combining with GNSS

The perfect combination of Dead Reckoning and GNSS is a perfect match for automotive navigation. Combining with GNSS signal, gyro steering information and CAN-Bus speed / pulse estimation, seamless real-time accurate positioning is achieved.   

Furthermore, the application of Dead Reckoning technology by LOCOSYS is good news to the car owners. Because even in the process of driving when GNSS signal is lost, they can accurately navigate and locate.
