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.

    Axis Communications has been an innovator in surveillance camera technology for over 20 years, and visitors to the company’s booth at the ITS America Annual Meeting can see just how advanced the systems have become. As the company points out, all surveillance cameras were analog 20 years ago. They delivered video via a coaxial cable to a recorder that stored the video on a tape. It was in 1996 that Axis Communications invented the network camera, which made it possible to connect a video camera directly to
