Untethered dead reckoning technology in smallest form-factor

u-blox has announced availability of its miniature Untethered Dead Reckoning (UDR) receiver EVA-M8E.

Measuring merely 7 mm x 7 mm, the EVA-M8E is the perfect positioning component for small-sized vehicle trackers. It provides untethered dead-reckoning performance without any electrical connection to the vehicle, using low cost inertial sensors. The EVA-M8E offers continuous positioning even before GNSS signals have been received, improves accuracy when GNSS signals are weak, and enables continuous low-latency positioning at 20 Hz to track highly dynamic events.

The EVA-M8E enables maximum flexibility in end-product design, requiring only a direct connection with the MEMS inertial sensor and SQI Flash memory. It adapts automatically to installations anywhere within a vehicle. It supports very low stand-by current consumption. UDR with adaptive signal strength compensation helps reduce the effects of small antenna and poor installations. This technology makes the EVA-M8E ideal for extremely small after-market road-vehicle applications such as usage-based insurance and theft alarms.

Along with all u-blox M8 receivers, the EVA-M8E supports GPS, GLONASS, BeiDou, Galileo, QZSS and SBAS constellations. It further provides superior positioning accuracy in urban canyons, tunnels, and parking garages.

"The EVA-M8E enables innovative products and services for high volume after-market telematics," says Andrew Miles, Product Manager Dead Reckoning at u-blox. "It also complements the main highlight of the NEO-M8U UDR module, which is ease-of-use."

The C93-M8E enables immediate evaluation of the u-blox's Untethered Dead Reckoning technology in most vehicle applications.

EVA-M8E samples and the C93-M8E are available now. The modules will be in full production in Q4 2016.

Consumer preferences drive the silicon industry. Each generation of mobile phones has to be thinner than the last. The same scenario happens with computers, as consumers demand more speed. These market forces have led to further and further shrinkage in silicon geometries, as consumer device manufacturers try to push the boundaries of silicon performance.
