FREMONT, CA: Telit, a provider of Internet of Things (IoT) solutions, announces the availability of SL869-3DR for tracking the location of in-vehicle systems. The new offering, SL869-3DR, leverages information from internal gyros, accelerometers and barometric pressure sensor to perform dead reckoning (DR) and determine the exact position of the vehicle.
SL869-3DR is a flash-memory based module designed to provide seven degrees of freedom (DOF) combining with micro electrochemical systems (MEMS). The advanced design of the internal sensor array along with the Telit MEMS-only Dead Reckoning (MoDR) software and intellectual property further enhances the accuracy of dead reckoning. The Telit MoDR solution provides real time data to the host application without connecting to the vehicle for wheel-ticks speed and reverse-gear data.
Advancements of SL869-3DR
The SL869-3DR design supports GPS, QZSS, GLONASS, Beidou and Galileo. The MoDR technology of Telit integrates withvarious sensors to bolster the position accuracy of the vehicle. The antenna ON feature enables the host application to provide real time information to the end user about the defects in the system. The low-noise amplifier in the antenna enables better sensitivity results in complex environments.
“A significant number of the millions of commercial vehicles and fleets on the roads today are still operating with no or unreliable navigation systems because installation costs to connect the device to vehicle sensors are too high and require very specialized skills,” says Felix Marchal, Executive Vice President of GNSS and Short Range Wireless. “With the SL869-3DR we overcome that barrier because it enables devices that you simply connect to vehicle power and go. Up until now, ‘power-and-go’ navigation systems have largely relied on open-sky visibility, which is not typically where most commercial fleets operate. They are moving through tunnels, urban canyons and other environments where these systems cannot produce a position solution. Reliable MEMS-only dead reckoning, or MoDR™ as we call it, relies on very complex mathematical modeling and expert design of the sensor array. Developers must therefore, thoroughly scrutinize performance of the different products in the market. I am delighted that the SL869-3DR has outperformed competing products in its class across a wide range of test cases.”
