{"title":"SparkPNT GNSS Flex Module with mosaic-G5 P3","handle":"sparkpnt-gnss-flex-module-mosaic-g5-p3","url":"/products/sparkpnt-gnss-flex-module-mosaic-g5-p3","description":"This GNSS Flex module brings Septentrio's compact mosaic-G5 P3 receiver to the SparkPNT Flex ecosystem, giving advanced navigation projects high-precision positioning in a small, low-power format.It is designed for autonomous systems, robotics and portable surveying tools where size, weight and power matter. The module connects to a GNSS Flex carrier board through standardised headers and breaks out USB, dual UARTs and key timing signals.The board has a U.FL connector for an external active multi-band GNSS antenna. For a sturdier antenna connection, it can be used with the SparkFun GNSS Flex pHAT, which provides an SMA connector bridged to U.FL via a short U.FL cable.Configuration and monitoring are supported through Septentrio RxTools or a command-line interface over USB or serial. Documentation includes design files, schematic, KiCad files, board dimensions, STEP file, hookup guide, datasheets, firmware manual and hardware repository.Features: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, offering protection against jamming and spoofing to ensure reliability in hostile RF environments.Multi-Band & Multi-Constellation: Tracks all signals from all major constellations GPS, GLONASS, Galileo, BeiDou and QZSS simultaneously.Flexible Protocols: Supports industry-standard NMEA, RTCM v3.x, and the Septentrio Binary Format (SBF).Sophisticated Software: Configure and monitor the module using Septentrio's RxTools suite or via a command-line interface over USB or serial.Interfaces: Access two hardware UARTs, two GPIO pins, two PPS outputs, and two Event inputs through the pHAT's headers.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:GNSS Flex Module: mosaic-G5 P3GNSS Receiver: Septentrio mosaic-G5 P3 GNSS ReceiverGNSS Constellation: GPS (USA)GNSS Constellation: GLONASS (Russia)GNSS Constellation: Galileo (EU)GNSS Constellation: BDS (China)GNSS Constellation: QZSS (Japan)Support: SBAS / QZSS SupportHeaders: Two 2x20-pin, 2mm-pitch female headersSocket: 40-pin socket for GNSS Flex pHAT / BreakoutPower: 3.3VPower: Backup powerPower: USB bus detect (not a power source)USB: USB (x1)UART: UART (x2)I2C: I2C busPPS signal: PPS signal (x2)PVT signal: PVT signal (x1)RTK signal: RTK signal (x1)Event signal: Event signal (x2)u.fl Connector: GNSS Antenna (Active, Multi-band)u.fl Connector: 3.3V power for an active antennaDimensions: 44.0mm x 34.0mm (Approx. 1.73\" x 1.34\")Mounting holes: Four mounting holesMounting holes: 4-40 screw compatibleHole centres: 39.0mm x 29.0mmHeader spacing: 36.0mmWeight: 9.20gUSB: mosaic-G5 P3 USB (D+ and D-)I2C: N/AFlex COM1: mosaic-G5 P3 UART1 (TX and RX only)Flex COM2: mosaic-G5 P3 UART2 (TX, RX, RTS, and CTS)Flex COM3: N/CFlex COM4: N/CPPS1: mosaic-G5 P3 PPS1PPS2: mosaic-G5 P3 PPS2EVENTA: mosaic-G5 P3 EVENTAEVENTB: mosaic-G5 P3 EVENTBRTK LED: mosaic-G5 P3 GPIO2PVT LED: mosaic-G5 P3 GPIO1Voltage 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)GPS Frequency Bands: L1C/A, L1C, L2C, L2PY, L5GLONASS Frequency Bands: L1CA, L2CA, L2P, L3 CDMABeidou Frequency Bands: B1I, B1C, B2a, B2b, B2I, B3IGalileo Frequency Bands: E1, E5a, E5b, E6QZSS Frequency Bands: L1C/A, L1 C/B, L2C, L5, L6Cold Start: < 35sWarm: < 10sReacquisition: 1sEvent Accuracy: < 3nsUpdate Rate: 20HzLatency: < 10msVANT Voltage: 3.3VMax current: 150mAInterface: UART (x2)Interface: USB device (2.0, HS)Interface: GPIO user programmable (x2)Interface: Event markers (x2)Interface: Configurable PPS out (x2)Protocol: Septentrio Binary Format (SBF)Protocol: NMEA 0183, v2.3, v3.03, V4.0Protocol: RTCM v3.x (MSM included)Package Size: 16.4mm x 22.8mm x 2.4mmWeight: 2.2gRequires an external multi-band antenna and a GNSS Flex carrier board.","vendor":"SparkFun","product_type":"GNSS Module","in_stock":true,"options":[],"variants":[{"id":16019,"title":"Default Title","sku":"SF-GPS-29209","mpn":"GPS-29209","price":1278.35,"on_sale":false,"in_stock":true,"available_quantity":5}]}
