Compact UDR receiver suited for small-sized vehicle trackers

u-blox has announced a miniature UDR (Untethered Dead Reckoning) receiver which measures just 7x7mm, making it suited for small-sized vehicle trackers. The EVA-M8E provides untethered dead-reckoning performance without any electrical connection to the vehicle, using low cost inertial sensors and offers continuous positioning even before GNSS signals have been received.

The EVA-M8E improves accuracy when GNSS signals are weak and enables continuous low-latency positioning at 20Hz to track highly dynamic events.

The UDR receiver 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 suitable 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.

Andrew Miles, Product Manager, Dead Reckoning, u-blox, commented: "The EVA-M8E enables innovative products and services for high volume after-market telematics. 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 UDR 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.
