GPS has replaced the map in recent years. More and more people use these devices as their preferred methods of navigation. Where once they relied on detailed maps to see where they were going, now they use a GPS that tells them exactly when and where to turn left or right.
However, a GPS is not perfect. It has several limitations. In order to be used, it needs to receive signals from a network of satellites. In urban areas tall buildings or tunnels can block the signal leaving the user to take wild guesses where he has to go next.
Swiss semiconductor manufacturer U-Blox comes with a solution for this particular problem. Their latest navigation chip is able to use a new system called “3D Automotive Dead Reckoning,” or “3D ADR.” The system no longer relies only on satellites to establish the position of the vehicle.
The 3D ADR tracks a vehicle’s speed, horizontal movement, and elevation. It uses an array of sensors, including an accelerometer, speed sensors and gyroscope. The elevation is important in order to establish if the vehicle is in a multi-story parking because they are usually GPS dead zones. In this way the 3D ADR keeps track of a vehicle’s position without relying on satellites. It also does not need to re-orient itself whenever it loses connection.
3D ADR is a chip that can work flawlessly with a car’s built-in sensors and navigation system. It can be installed easily and does not need to be configured in any way. The manufacturers stated that their chip will work with most vehicles regardless of their drivetrain configuration. Unfortunately, for the moment the firm is not planning on making a version that also works on tablets or smartphones.
The 3D ADR is a chip that can fill the blanks whenever GPS fails. It makes sure to keep you on track and helpz you in GPS dead zones. Would you buy it?
