u-blox launches miniature untethered dead reckoning receiver

Published: June 23, 2016 | Thalwil, Switzerland 

u-blox has launched its miniature Untethered Dead Reckoning (UDR) receiver EVA-M8E, which measures 7 mm x 7 mm, and 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 technology 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.

Andrew Miles, Product Manager Dead Reckoning at u-blox, said:

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.

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, it supports GPS, GLONASS, BeiDou, Galileo, QZSS and SBAS constellations. It further provides positioning accuracy in urban canyons, tunnels, and parking garages.
