OBDII Odometer
The OBDII Odometer is a smart interface cable that communicates with a vehicle’s onboard computer to provide vehicle speed as external aiding for our INS solutions.
The OBDII odometer outputs real-time vehicle speed over an RS232 serial data interface. When connected to one of Advanced Navigation’s INS products it allows for outstanding navigation accuracy when GPS is not available.
Features
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.
