The OBDII Odometer is a smart interface cable that communicates with a vehicle’s on-board computer to provide vehicle speed as external aiding for our INS solutions

OBDII (On-board Diagnostics) is a standardised electrical data interface installed in most modern road vehicles that allows external systems to read information from the vehicle computer in real time. By connecting an OBDII Odometer Iterface cable to one of Advanced Navigation’s INS products, outstanding improvements can be made to dead reckoning performance by supplying the vehicles speed.

ABS Speed and Reverse Detection

The OBDII Odometer can retrieve a very accurate and high resolution vehicle speed from the ABS system (Anti-lock Braking System) on some vehicles. On other vehicles the transmission still offers an accurate speed. Some vehicles also offer reversing detection via the gearbox position.

Miniature Durable Design

The OBDII Odometer has a miniature in-line design that is easy to fit into any vehicle. It features a strong ABS plastic shell and tough strain relieved cabling.

Reliability

The OBDII Odometer is built for reliability. It is built on a safety based real time operating system and all software is designed and tested to safety standards. The hardware is designed to MIL specs and has fully galvanically isolated power and communications.
