{"title":"SparkFun RTK mosaic-X5","handle":"sparkfun-rtk-mosaic-x5","url":"/products/sparkfun-rtk-mosaic-x5","description":"The SparkFun RTK mosaic-X5 is a high-precision GNSS positioning and navigation receiver built around the Septentrio mosaic-X5 multi-constellation, multi-frequency module. 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.\n\nConfigurable 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.\n\nAn 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.\n\nKey Features\n\n\nSeptentrio mosaic-X5 Module – 448-channel multi-constellation, multi-frequency GNSS receiver with AIM+ interference mitigation\n\nRTK Positioning – 6 mm + 0.5 PPM horizontal accuracy with correction data; configurable as base or rover\n\n100 Hz Update Rate – Position updates 100 times per second for real-time applications\n\nMulti-Format Logging – Direct logging to microSD in RINEX, NMEA, SBF, RTCM, and CMR formats\n\nESP32-WROVER Processor – Provides WiFi/Bluetooth connectivity and Ethernet-to-WiFi bridging (16 MB flash, 8 MB PSRAM)\n\nDual Ethernet Interfaces – Independent 10/100 Mbps connections for mosaic-X5 and ESP32 with auto-negotiate and Auto MDI/MDI-X\n\nPower-over-Ethernet – PoE support (36–57 V) for single-cable installations\n\nOLED Display – 128 × 64 pixel display for status monitoring\n\nAluminium Enclosure – Custom extruded case with machined end panels and IP42 ingress protection\n\nMultiple Power Options – USB-C (mosaic-X5 or ESP32), PoE, or external DC (9–36 V via screw terminals, fully isolated)\n\n5 V Active Antenna – SMA connector provides 5 V power for the included L1/L2/L5 surveying antenna\n\n\nSupported GNSS Signals\n\n\nGPS – L1C/A, L1PY, L2C, L2P, L5\n\nGLONASS – L1CA, L2CA, L2P, L3 CDMA\n\nBeidou – B1I, B1C, B2a, B2b, B2I, B3\n\nGalileo – E1, E5a, E5b, E5 AltBoc, E6\n\nQZSS – L1C/A, L1 C/B, L2C, L5\n\nNavIC – L5\n\nSBAS – EGNOS, WAAS, GAGAN, MSAS, SDCM (L1, L5)\n\nL-band – On-module support for correction services\n\n\nI/O Connections\n\n\nmosaic-X5 COM1 UART – TX, RX, RTS, CTS\n\nEvent Inputs – EVENT-A and EVENT-B\n\nTiming Output – PPSO pulse-per-second output\n\nLog Button Input – External log trigger\n\nESP32 UART – TX, RX, RTS, CTS\n\nESP32 I²C – With level-shifting\n\n\nIdeal For\n\nHigh-precision GNSS surveying and mapping\nRobotics and autonomous vehicle navigation\nRTK base station installations\nPrecision agriculture\nResearch and RINEX data collection\n\n\nPackage Contents\n\n1× SparkFun RTK mosaic-X5 (cased receiver)\n1× L1/L2/L5 GNSS Surveying Antenna\n1× Reinforced RG58 TNC-SMA Cable (10 m)\n1× SMA WiFi/Bluetooth Antenna\n1× 32 GB microSD Card (Class 10)\n1× USB-C Power Supply (5 V, 1 A wall adapter)\n1× USB-C Cable (A to C, 2 m)\n1× Ethernet Cable (CAT-6, 1 m)\n1× Quick Start Guide\n\n\n\nNote: The included USB-C power supply uses a US-style plug.
