Utilizing information obtained from internal gyro, accelerometer, barometer, and barometric pressure sensors
A flash memory-based module that simultaneously tracks three or more satellites

Telit (CEO Derek Sang) announced the launch of its new GNSS module, the SL869-3DR. Available worldwide, the SL869-3DR enables dead reckoning (DR) in location tracking applications and in-vehicle systems by utilizing information obtained from internal gyros, accelerometers, and barometer barometric pressure sensors.

This product can provide accurate location information directly from multiple satellite receivers or through a DR system that requires only an antenna and power to receive satellite signals without connecting other external devices. Through this, system integrators can design various commercial and consumer applications, including vehicle navigation and tracking devices, to operate on the dashboard using only the vehicle's power supply.

The SL869-3DR is a flash memory-based module capable of simultaneously tracking three or more satellites, and supports 7 Degrees of Freedom (DOF) through the integration of MEMS. Telit’s MEMS-specific dead reckoning software MoDR™ and an innovative internal sensor design based on patented technology provide turnkey DR performance to the host device.

In particular, the MoDR™ solution enables the transmission of stable position, speed, and time (PVT) information to a host application without the need for vehicle wheel tick and reverse gear data connections, even when out of GNSS coverage. In addition, it is designed with a standard footprint, allowing navigation and tracking system integrators to reuse existing device designs, thereby eliminating complexity from external sensors and other devices and helping to bring the latest technology to market more quickly.

The SL869-3DR supports multi-standard satellite navigation systems such as GPS, QZSS, GLONASS, BeiDou, and Galileo. Telit’s MoDR™ technology ensures high positioning accuracy even in areas where satellite reception is difficult, such as dense high-rise buildings, tall trees, tunnels, and parking lots, and supports sensor integration including accelerometers, gyroscopes, and barometers.

The antenna ON function, an antenna sensing feature, allows the host application to send notifications to the user in the event of a problem with the external antenna connection. Additionally, sensitivity can be increased in harsh environments through the use of an additional LNA. This product is a pin-to-pin compatible device with the existing SL869, SL869-V3, and SL869-ADR.
