How Can Your Navigation Systems Maintain Accuracy in Tunnels and Underground Parking?

LOCOSYS UDR modules seamlessly combine GNSS positioning with gyroscope and CAN-Bus data to deliver continuous accurate navigation even when satellite signals are completely lost. Our proven technology, tested in Tokyo's 18.6 km Yamate tunnel, ensures your automotive navigation systems never lose track of vehicle position in challenging environments. Contact us to integrate UDR dead reckoning into your next-generation navigation products.

The perfect integration of dead reckoning and GNSS technology makes LOCOSYS UDR modules the ideal solution for automotive navigation applications. Proven through rigorous field testing including an 18.6 km test in Tokyo's Yamate tunnel, our UDR modules maintain continuous accurate navigation and location tracking throughout the driving process, regardless of GNSS signal availability. This advanced dead reckoning technology ensures vehicle positioning systems deliver uninterrupted performance in complex urban environments, underground facilities, and any GNSS-denied scenarios where traditional satellite positioning fails, providing automotive manufacturers and navigation system integrators with a reliable solution for next-generation vehicle navigation systems.

Introduction

LOCOSYS Untethered Dead Reckoning product is that it provides a high refresh rate for location data or an instant High Navigation Rate (HNR) output.

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.
