Dead Reckoning - SL869-ADR

Turn-key GNSS solution for Automotive Dead Reckoning applications

Leading telematics solutions providers choose Telit SL869 GNSS modules for integration into telematics devices and automotive applications. The SL869-ADR is a powerful, automotive grade GNSS system equipped with Automotive Dead Reckoning software, embedded 6-axis sensor MEMS and a powerful core. Whenever GNSS coverage is missing or compromised, the SL869-ADR receiver provides the host application with accurate estimates of a vehicle’s or moving device’s position and velocity by combining speed and heading data coming from internal sensors into with Odometer data coming from the car.

Dead Reckoning boosts the accuracy in areas with adverse GNSS conditions like urban canyons, tunnels, parking garages, etc. When GNSS coverage is lost, the Dead Reckoning software fills in the gaps.

With the SL869-ADR, enable gap-free navigation and multi-constellation GNSS with GPS, Glonass, Beidou and Galileo alongside A-GNSS onboard generation and server-generated file injection.

This turn-key solution includes a powerful SDK for customization and is pin-to-pin compatible with SL869-DR and SL869-3DR for scalable applications .
