ST-1612i-DGX Dead Reckoning (DR) module is the perfect solution for automotive application. The ST-1612i-DGX is embedded 3D accelerometer, 3D gyroscope Micro-Electro-Mechanical Systems (MEMS) sensor, equipped with DR software, and powered by STMicroelectronics Teseo III. With adverse GNSS conditions in urban canyons, tunnels, or parking garages where DR boosts the accuracy, and the software fills the gaps. It supports three dimensional DR. This module can simultaneously acquire and track multiple satellite constellations that include GPS, GLONASS, GALILEO and QZSS. It features high
sensitivity, low power and ultra small form factor, and provide user the superior performance.
ST-1612i-DGX modules use GNSS chips qualified according to AEC-Q100 and manufactured in IATF 16949 certified sites.
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.
