Dead Reckoning - SL869-ADR


The Jupiter SL869-ADR is a new representative of the Telit Dead Reckoning Family. SL869-ADR is equipped with Automotive Dead Reckoning software, embedded 6-axis sensor MEMS and a new powerful core. Whenever GNSS coverage is missing or compromised, the SL869-ADR receiver provides the host application with accurate estimates of 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.

The embedded 6-axis MEMS sensor makes the integration into the navigation system straightforward. Dead Reckoning boosts the accuracy in areas with adverse GNSS conditions like urban canyons, tunnels, parking garages, etc. When GNSS coverage is lost, the DR software fills in the gaps.

The SL869-ADR is able to track GPS, Glonass, Beidou and Galileo constellations and supports A-GNSS onboard generation as well as A-GNSS server-generated file injection.

The SL869-ADR provides a proven gap-free navigation solution that compensates for possible difficult GNSS conditions for different applications like Automotive, telematics, aftermarket, and fleet tracking.


The xL869 is Telit’s GNSS Unified Form Factor family which allows customers to select among different GNSS technologies. Modules in this family are offered in a 16 x 12.2 mm, 24-pad, LCC package supporting GPS, GLONASS, Galileo, and QZSS constellations.

Our positioning product portfolio is the result of over twenty years of experience in GNSS applications. Telit has developed a range of products compatible with the well-known GPS constellation as well as its Russian counterpart GLONASS. Moreover, our portfolio is fully aligned with the upcoming service launch of Europe’s Galileo constellation. Valuable features such as Dead Reckoning, Precision Timing, as well as speed and reliability assured by multiconstellation coverage, provide additional benefits for your application.

Your application development effort can also benefit significantly from the seamless integration between Telit’s cellular and positioning modules. This bundling of cellular and positioning modules significantly reduces development complexity without adding costs. Multi-constellation positioning products applied together with our eCall / ERAGLONASS compliant cellular modules bring you ready-to-use emergency automotive tracking solutions for the European and Russian markets.

Typical applications include fleet management systems, European GPS-assisted road tolling systems, cellular base stations, in-car navigation systems, automotive telematics systems, and GPS-based personal sports training monitors.
