Introduction
Dead-Reckoning (DR) is a new feature implemented in some high-end automotive navigation systems in order to compensate for
the limitations of GPS technology. The solution ensures uninterrupted navigation and tracking when satellite signals are blocked or
unavailable, such as near tall buildings, mountains, canyons, in tunnels or in underground parking. With Dead Reckoning, the AVL-
2000PLUS can still provide continuous position reporting even during GPS satellite blockage.

Built-in Global Positioning System (GPS) with Dead Reckoning Support
A built-in gyroscope is used to measure angular velocity. It provides highly accurate results when measuring an angular turn in any
direction. The OBD-II, on the other hand, can accurately measure the speed of the vehicle. By combining gyroscopes with OBD-
II, the AVL-2000PLUS is able to perform non-stop calculation of the dead reckoning position, orientation, and velocity (direction
and speed of movement) of a moving object without any external references. It also eliminates the trouble and cost of a traditional
speedometer cable installation. The AVL-2000PLUS is an ideal choice to enhance GPS performance and improve overall tracking
ability.
Simple “Plug-and-Play” Hard to Install
Traditional data retrieval via wired speedometer is
cumbersome and time-consuming.

AVL-2000PLUS uses standard OBD-II interface plug,
allowing for quick and easy access to cruise data.
