Supporting GPS, GLONASS, Beidou, Galileo, NavIC, SBAS, and QZSS across L1/L2/L5 bands, the 448-channel receiver delivers centimetre-level positioning accuracy when used with RTK corrections. Configurable as either an RTK Base (feeding corrections to rovers) or an RTK Rover (receiving corrections for 6 mm + 0.5 PPM horizontal accuracy), the mosaic-X5 supports position updates at up to 100 Hz — ideal for robotics and autonomous systems. The receiver runs a full internal web server for configuration and monitoring via any standard browser, and supports logging in RINEX, NMEA, and Septentrio SBF formats. An ESP32-WROVER processor (16 MB flash, 8 MB PSRAM) provides WiFi and Bluetooth connectivity. The mosaic-X5 can connect directly to an Ethernet network (with Power-over-Ethernet support), or link its Ethernet port to the ESP32 for WiFi bridging. All I/O connections use robust 3.5 mm screw terminals with selectable 3.3 V or 5 V logic levels. The custom extruded aluminium case with machined end panels features slotted flanges for easy mounting.
