3-axis gyroscope for automotive applications

STMicroelectronics has introduced a world first - the market’s first 3-axis digital-output gyroscope that meets the industry-standard qualification for automotive integrated circuits (AEC-Q100). ST’s A3G4250D gyroscope newest angular-rate sensor aims to add positioning accuracy and stability to a wide range of automotive applications, including in-dash navigation, telematics and vehicle tolling systems.

6234 STMicroelectronics has introduced a world first - the market’s first 3-axis digital-output gyroscope that meets the industry-standard qualification for automotive integrated circuits (AEC-Q100).

ST’s A3G4250D gyroscope newest angular-rate sensor aims to add positioning accuracy and stability to a wide range of automotive applications, including in-dash navigation, telematics and vehicle tolling systems. ST says that accurate measurements of angular-motion detection with its automotive-qualified gyroscopes will significantly enhance dead-reckoning and/or map-matching capabilities in car navigation and telematics applications, the company claims. In situations when a GPS signal can’t be seen, such as indoors and in urban canyons between tall buildings, dead-reckoning systems compensate for loss of satellite signal by monitoring motion, distance travelled and altitude.

Precise gyroscope readings can also improve map-matching, the process of aligning a sequence of observed user positions with the road network on a digital map, used in a number of applications.

    Toyota Research Institute-Advanced Development (TRI-AD), technology company Maxar Technologies and NTT Data are working together to build high-definition (HD) maps for autonomous vehicles (AV) using satellite imagery. TRI-AD carried out an analysis, saying that current HD maps cover less than 1% of the global road network and there is a need to broaden the coverage of urban areas and local roads before AVs can become a mainstream mobility technology. A HD map created from satellite imagery would all

    Surveillance camera technology has come a long way over the last 20 years as visitors to the Axis Communications booth here at ITS America 2016 San Jose will see. The company invented the network camera in 1996, making it possible to connect a video camera directly to a computer network (commonly referred to as IP video). The shift from analog to IP has changed the global security market. According to Axis, with network cameras being based on open IP standards, authorised users can get secure and flexible a
