Miniature UDR receiver targets small-sized vehicle trackers

Measuring just 7mm x 7mm, the EVA-M8E from U-blox is being hailed as the ideal positioning component for small-sized vehicle trackers. It provides untethered dead-reckoning (UDR) 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 20Hz 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 cutting edge 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, says the company. "The EVA-M8E enables innovative products and services for high volume after-market telematics," says Andrew Miles, dead reckoning product manager, U-blox. "It also complements the main highlight of the NEO-M8U UDR module, which is ease-of-use." Further, the C93-M8E offers immediate evaluation of the u-blox's Untethered Dead Reckoning technology in most vehicle applications.
