How Can Your Navigation System Maintain Accuracy Through Tunnels and Urban Canyons?

The ST-1612i-DBX's integrated 3-axis gyroscope and accelerometer with advanced dead reckoning software fills GNSS signal gaps in tunnels, parking garages, and dense urban environments. With AEC-Q100 qualification and three-dimensional positioning, your navigation system delivers seamless, continuous tracking where conventional GPS fails. Contact us to receive technical specifications and integration support for your next-generation automotive navigation platform.

Manufactured in IATF 16949 certified facilities, the ST-1612i-DBX offers comprehensive automotive integration features including odometer wheel-tick pulse input, forward/reverse direction detection, CAN Bus support (ISO 15765-4), and compliance with SAE J2945/1 V2V safety communication requirements. The module's automatic configuration capability simplifies installation by adapting to wheel tick input or speed signals and compensating for in-vehicle antenna characteristics. With its three-dimensional dead reckoning capability, sensor data output through UART, and ultra-low power consumption, the ST-1612i-DBX is the ideal positioning solution for automotive navigation systems, fleet management, M2M applications, and vehicle tracking devices that demand uninterrupted positioning accuracy across all driving environments.
