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 suits the EVA-M8E to 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 provides superior positioning accuracy in urban canyons, tunnels, and parking garages. The C93-M8E enables immediate evaluation of the u-blox's Untethered Dead Reckoning technology in most vehicle applications.
