u-blox 3D Automotive Dead Reckoning technology
Increasingly dense urban environments, park houses and multi-level interchanges pose a significant problem to navigation systems based on the reception of extremely weak satellite navigation signals.
As ever more systems (e.g. car navigation, road pricing, fleet management, emergency services, etc.) depend on reliable, uninterrupted positioning and navigation, “3-Dimensional Dead Reckoning” GNSS, the ability to calculate a position in the X, Y, and Z axis when satellites signals are blocked or impeded is becoming increasingly important.
3D Automotive Dead Reckoning chip: a new dimension in navigation
3-Dimensional Automotive Dead Reckoning (“3D ADR”) aids traditional GPS/GNSS navigation via intelligent algorithms based on distance, direction and elevation changes made during satellite signal interruption. u-blox' 3D ADR GNSS chip UBX-M8030-Kx-DR blends satellite navigation data with individual wheel speed, gyroscope and accelerometer information to deliver accurate positioning regardless of changes in a vehicle’s speed, heading or elevation, even when satellite signals are partially or completely blocked. This is especially important when quick navigation decisions must be made immediately upon exiting tunnels and parkhouses.
The solution: GNSS satellite receiver chip enhanced with 3D Dead Reckoning
To solve these problems, u-blox has integrated 3D ADR functionality into its GNSS satellite receiver chip technology. For more information about u-blox' UBX-M8030-KA-DR satellite receiver chip with integrated 3D Automotive Dead Reckoning.
Hardware sensor interface for after-market devices
The standard quality grade
modules are dedicated 2D ADR solutions (GWT only) for after market installations with no access to the vehicle bus and no application processor for sensor data processing. Sensors are connected directly to the module: gyroscopes via SPI and ADC and the speedpulse information from the tachometer.
