The SL869-3DR is 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 to external devices or components other than an antenna for satellite signal reception and power. The module allows integrators to design zero-installation, in-vehicle navigation and tracking devices for fleets and other commercial or consumer applications that operate perched on the dashboard, connected only to vehicle power. The SL869-3DR is designed to support GPS, QZSS, GLONASS, Beidou and is Galileo ready.
