It offers the same leading performance as the mosaic-X5 in a package that is 60% smaller and consumes 40% less power.The receiver can track major global constellations including GPS, GLONASS, Galileo, BeiDou and QZSS, making it suitable for surveying, robotics and IoT builds where size, weight and power are important. An external active multi-band GNSS antenna is required and connects via the onboard SMA socket.The board is set up for integration with standard 0.1" headers, two Qwiic connectors, USB-C, a 4-pin JST-GH connector and a BlueSMiRF-compatible header for RTCM correction links. Configuration and monitoring can be handled using Septentrio’s RxTools suite or a command-line interface over USB or serial.Features:Compact size: Delivers mosaic-G5 performance in a package that is 60% smaller than the mosaic-X5.Low power: Consumes 40% less power than the mosaic-X5.Multi-band, multi-constellation: Tracks GPS, GLONASS, Galileo, BeiDou and QZSS simultaneously.Millimetre-Level Accuracy: Delivers 6mm horizontal and 1cm vertical accuracy with RTK.Precise Timing: Features a PPS timing resolution of 1.4ns and event-trigger accuracy <3ns, making it ideal for exact time-synchronisation applications.AIM+ Interference Mitigation: Equipped with Septentrio's AIM+ technology for protection against jamming and spoofing in hostile RF environments.Extensive Breakout: Twenty-one 0.1"-pitch PTH pins break out two UARTs, two configurable PPS outputs, two event triggers, and GPIOs.USB-C Connectivity: A native USB-C connector supports high-speed data transfer and configuration.Ready for RTK Corrections: The UART2 interface is broken out to a locking JST connector and a BlueSMiRF-compatible header, making it easy to connect an RF transceiver to receive RTCM corrections.Qwiic Compatible: Includes two Qwiic connectors for easy, solder-free integration into the SparkFun Qwiic Ecosystem.Flexible Protocols: Supports industry-standard NMEA, RTCM v3.x, and the highly efficient Septentrio Binary Format (SBF).Sophisticated Software: Configure and monitor the module using Septentrio's RxTools suite or via a robust Command-Line Interface (CLI) over USB or Serial.RTK Base functionality due Q2 2026: The initial mosaic-G5 P3 firmware does not support RTK Base and it can not generate RTCM corrections. Septentrio will add base station capability to the mosaic-G5 P3 and P3H in a firmware release currently planned for the Q2 2026.Specifications:Breakout receiver: Septentrio mosaic-G5 P3 GNSS ReceiverGNSS Constellation - GPS: GPS (USA)GNSS Constellation - GLONASS: GLONASS (Russia)GNSS Constellation - Galileo: Galileo (EU)GNSS Constellation - BDS: BDS (China)GNSS Constellation - QZSS: QZSS (Japan)SBAS / QZSS Support: YesUSB-C Connector: Yes4-pin JST-GH Connector: YesQwiic Connectors: x24-pin JST-SH: YesSMA Connector - GNSS Antenna: Active, Multi-bandSMA Connector - active antenna power: 3.3V power for an active antennaPTH pins: Twenty-one 0.1"-pitch PTH pinsVIN: 3.8V to 5.5V3.3V: x23.3V Enable: YesUART: x2PPS signal: x2LED indicators: x2Event indicators: x2Reset: YesGND: x4Dimensions: 43.2mm x 43.2mm (Approx. 1.70" x 1.70")Mounting holes: Four mounting holesMounting hole compatibility: 4-40 screw compatibleWeight: 11.15gmosaic-G5 P3 GNSS Receiver - Voltage Range: 3.135 to 3.465VTypical power consumption: 0.44WRTK Accuracy - Horizontal: 0.6cm (±0.5ppm)RTK Accuracy - Vertical: 1cm (±1ppm)Channels: 789 (simultaneous tracking)GNSS Frequency Bands - GPS: L1C/A, L1C, L2C, L2PY, L5GNSS Frequency Bands - GLONASS: L1CA, L2CA, L2P, L3 CDMAGNSS Frequency Bands - Beidou: B1I, B1C, B2a, B2b, B2I, B3IGNSS Frequency Bands - Galileo: E1, E5a, E5b, E6GNSS Frequency Bands - QZSS: L1C/A, L1 C/B, L2C, L5, L6Time to Fix - Cold Start: < 35sTime to Fix - Warm: < 10sTime to Fix - Reacquisition: 1sEvent Accuracy: < 3nsUpdate Rate: 20HzLatency: < 10msVANT Voltage: 3.3VMax current: 150mAInterface - UART: x2Interface - USB device: 2.0, HSInterface - GPIO user programmable: x2Interface - Event markers: x2Interface - Configurable PPS out: x2Protocol - Septentrio Binary Format: SBFProtocol - NMEA: NMEA 0183, v2.3, v3.03, V4.0Protocol - RTCM: RTCM v3.x (MSM included)Package Size: 16.4mm x 22.8mm x 2.4mmModule weight: 2.2gA good choice for precision navigation, survey gear, robotics and timing projects where compact hardware and RTK performance matter.
