Telit autonomous nav module uses internal sensors, GNSS

November 7, 2016By

Telit has announced the commercial availability of the SL869-3DR, a GNSS module for global use that leverages information from internal gyros, accelerometers and a barometric pressure sensor to perform dead-reckoning navigation for application areas such as track and trace and in-vehicle systems. The module delivers accurate position data either directly from its multi-constellation receiver or from a fully autonomous dead-reckoning system, requiring no connections... read more

u-blox unveils untethered dead-reckoning receiver for vehicles

June 23, 2016By

u-blox’s has revealed its latest receiver, the miniature Untethered Dead Reckoning (UDR) EVA-M8E. Measuring 7 millimeters by 7 millimeters, the EVA-M8E is designed to provide positioning 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... read more

Webinar probes future road: V2X communication, positioning and safety

June 14, 2016By

Details of this Thursday’s Connected Car webinar emerged as speakers gathered today to share their presentation materials. (You can join this free webinar here.) A key concept is that no single technology can provide the required position accuracy in all environments. A combination of core GNSS technologies is needed: SSR-RTK with correction data (satellite and LTE), multi-GNSS for large number... read more

Trimble Introduces New DR+GPS Module for Vehicle and Asset Tracking Applications

May 15, 2012By

Trimble has introduced the Aardvark DR+GPS module that combines dead reckoning (DR) with GPS technology on a single, compact board. The Trimble Aardvark DR+GPS module provides positioning information when GPS signals are limited or not available, such as in urban canyons and tunnels. The Aardvark DR+GPS module is being marketed as a solution for system integrators or OEMs who are adding dead reckoning capabilities to vehicle navigation, fleet management and asset tracking systems. read more
