Buy GNSS Module With 1.5-Meter Accuracy and 18Hz Fix Rate
The MultiNav Pro+™ — When You Need to Buy a GNSS Module That Actually Performs
If you have ever tried to build a drone, autonomous robot, precision tracking system, or field research tool, you already know the problem. Most GNSS modules on the market are either too slow, too inaccurate, too power-hungry, or so expensive they belong in a defense contract. The gap between "good enough for hobbyists" and "actually professional" has always been wide — and expensive to cross.
The RFOXiA MultiNav Pro+™ closes that gap.
This is the GNSS module built for developers, engineers, drone builders, and researchers who need real precision without paying enterprise prices. 1.5-meter accuracy. 18Hz fix rate. First fix in one second. Concurrent support for GPS, Galileo, GLONASS, and BeiDou — all in a 26mm x 22mm module that draws just 25–30mA.
When you are ready to buy a GNSS module that is truly ready for professional-grade applications, this is where that search ends.
Why Most GNSS Modules Fall Short
The GNSS module market is flooded with options. Most of them share the same weaknesses:
- Fix rates of 1–5Hz — fine for static applications, completely inadequate for anything moving quickly. A drone traveling at 60 km/h moves 16 meters in one second. At 1Hz, you are not tracking a drone — you are guessing where it was.
- Accuracy of 2.5–5 meters CEP — workable for turn-by-turn navigation on roads, not acceptable for precision agriculture, inspection drones, or survey-grade positioning.
- Single-constellation support — modules that only lock onto GPS are vulnerable to satellite geometry gaps, multipath interference, and sky obstruction.
- No open-source driver support — proprietary black boxes that lock you into one toolchain, one IDE, one way of doing things.
- Fragile first-fix times — modules that take 30–60 seconds to establish a lock are useless in fast-deployment field scenarios.
The MultiNav Pro+ was engineered specifically to solve every one of these problems.
Built on the u-blox MIA-M10Q — The Right Foundation
At the heart of the MultiNav Pro+ is the u-blox MIA-M10Q — one of the most advanced GNSS chips available in the compact module category. u-blox is not a name associated with compromise. Their chips power navigation systems in automotive, industrial IoT, and precision agriculture applications worldwide.
The MIA-M10Q brings that same engineering pedigree to the MultiNav Pro+, enabling:
- Concurrent reception of all four major satellite constellations simultaneously
- Ultra-low power operation without sacrificing tracking performance
- Advanced multipath mitigation for operation in challenging environments
- Industry-standard NMEA protocol output over UART and I2C
This is not a generic GNSS module with a cheap chip and a passive antenna glued to a PCB. This is a precision instrument designed from the ground up for developers who cannot afford to compromise on location data.
Performance Specifications That Change What Is Possible
Numbers matter. Here is what the MultiNav Pro+ delivers:
| Specification | Value |
|---|---|
| Accuracy (CEP) | < 1.5 meters |
| Fix Rate | Up to 18Hz |
| Time to First Fix | 1 second (hot start) |
| Satellite Constellations | GPS, Galileo, GLONASS, BeiDou |
| Operating Current | 25–30mA |
| Module Dimensions | 26mm x 22mm |
| Interface | UART (TX/RX), I2C (SCL/SDA) |
| Operating Voltage | 1.8V and 3.3V |
| Antenna | Integrated High-Gain Chip Antenna |
| Certification | FCC Certified |
The 18Hz fix rate is the specification that matters most for dynamic applications. At 18 position updates per second, you have enough resolution to track a racing drone, log the flight path of a fixed-wing UAV, guide an autonomous ground vehicle around obstacles, or record centimeter-level movement in research applications. Nothing else in this price range comes close.
First fix in one second means your system is operational almost immediately on power-up. For field deployments where time matters — rescue operations, inspection missions, agricultural surveys — that responsiveness is critical.
Compact and Power-Efficient: Engineered for Real Deployments
Size and power are not afterthoughts in hardware engineering — they define what applications are actually possible.
At 26mm x 22mm, the MultiNav Pro+ is compact enough to integrate into wearables, fit inside tight drone frames, embed in agricultural sensor nodes, and mount on miniaturized research payloads. It does not require a large carrier board or complex RF shielding to operate effectively, because the integrated high-gain chip antenna handles signal reception internally.
At 25–30mA operating current, the MultiNav Pro+ is power-efficient enough to run continuously from a modest LiPo cell for extended periods. Pair it with the RFOXiA Power/Program Kit — which provides 24 hours of runtime from a 5-minute supercapacitor charge — and you have a field-deployable precision navigation system that outlasts the mission.
This combination of small footprint and low power draw makes the MultiNav Pro+ particularly well-suited for:
- Multirotor drones — where every gram and milliamp counts
- Fixed-wing UAVs — long-duration flights demand efficient avionics
- Agricultural sensor nodes — solar-powered or battery-powered field stations
- Wearable tracking devices — small form factor enables discreet integration
- Autonomous ground vehicles — embedded in compact chassis designs
Versatile Connectivity for Any Toolchain
One of the most common frustrations with GNSS modules is interface incompatibility. You choose a chip, only to discover it requires a proprietary serial protocol, a specific voltage level you are not running, or a complex initialization sequence that is poorly documented.
The MultiNav Pro+ eliminates this friction entirely.
UART support (TX/RX) gives you direct compatibility with virtually every microcontroller on the market — from Arduino boards to STM32 to ESP32 to Raspberry Pi. Wire up two lines and you are receiving NMEA sentences.
I2C support (SCL/SDA) allows the MultiNav Pro+ to share a bus with other sensors and peripherals, reducing pin count requirements and simplifying wiring in complex builds.
Dual voltage support (1.8V and 3.3V) means you do not need level shifters or voltage regulators for most modern microcontroller platforms. The module works natively with both low-power 1.8V MCUs and standard 3.3V systems.
This is a module that speaks your language, whatever language your hardware speaks.
Open Source Driver — Your Code, Your Rules
RFOXiA believes that when you buy hardware, you own it completely — including the right to understand exactly how it works and modify it freely.
The MultiNav Pro+ ships with a fully open-source C language driver library that implements the NMEA standard protocol. This means:
- Arduino IDE compatibility — drop the library in, include the header, and you are parsing GPS coordinates in minutes
- Any toolchain support — CMake, PlatformIO, STM32CubeIDE, bare-metal — the C library ports to wherever your project lives
- Full NMEA protocol access — GGA, RMC, VTG, GSA, GSV sentences and more, fully parsed and ready to use
- No black box mystery — read the source, understand the implementation, customize as needed
- Community contributions — as an open-source project, improvements and examples from the community benefit every user
This open approach is fundamental to RFOXiA's philosophy. Democratizing connectivity means giving developers actual access — not just to hardware, but to the full software stack that makes it work.
U-Center Software Integration — Professional Visualization
Because the MultiNav Pro+ is built on the u-blox MIA-M10Q, it is fully compatible with u-blox's U-Center software — a professional GNSS evaluation and configuration tool used by engineers worldwide.
U-Center gives you:
- Satellite sky view — visualize exactly which satellites are in view and their signal strength in real time
- Live track logging — record movement paths with full coordinate and timestamp logging
- Configuration interface — adjust fix rate, constellation selection, NMEA output configuration, and power modes through a graphical interface
- Signal analysis — dig into carrier-to-noise density (C/N0) metrics for every tracked satellite
- Data export — export logs in standard formats for post-processing in GIS tools, MATLAB, or custom analysis pipelines
This is the same tool that professional GNSS engineers use to characterize and validate navigation systems. Having it available for a $49 module is not something you will find from generic Chinese module manufacturers — it is a direct benefit of choosing a design built on a proper professional chipset.
Applications: Where the MultiNav Pro+ Excels
The combination of 1.5-meter accuracy, 18Hz fix rate, and concurrent multi-constellation support makes the MultiNav Pro+ applicable across a wide range of professional and research use cases:
Drone and UAV Navigation
High fix rate is non-negotiable for anything flying. Whether you are building a racing quad, a survey drone, a delivery UAV, or a long-range fixed-wing aircraft, 18Hz position updates give your flight controller the data it needs to hold position, execute waypoint missions, and log accurate flight paths. The compact size integrates cleanly into any frame.
Precision Agriculture
Field robots, soil sampling drones, variable-rate applicators, and autonomous tractors all require sub-2-meter positioning to operate on crop row spacing without overlap or gaps. The MultiNav Pro+ delivers that accuracy continuously, at low power, in outdoor environments.
Asset and Fleet Tracking
Vehicle trackers, container monitors, and mobile asset systems need fast, accurate position fixes. The MultiNav Pro+'s one-second first-fix time means even intermittently powered systems come online and locate immediately.
Research and Environmental Monitoring
When paired with the RFOXiA Sensors Module, the MultiNav Pro+ creates a GPS-stamped environmental data stream — temperature, humidity, air quality, and pressure all geolocated and timestamped to 18Hz resolution. This combination is ideal for mobile environmental surveys, wildlife tracking, and atmospheric research.
Robotics and Ground Vehicles
Autonomous ground vehicles navigating outdoors require reliable, high-rate positioning. The MultiNav Pro+ integrates cleanly with popular autopilot and navigation stacks, providing the foundation for outdoor autonomous navigation.
Wearable and Personal Tracking
At 26mm x 22mm and 25–30mA, the module is small and efficient enough for wearable devices — activity trackers, personal safety devices, athletic performance monitors, and expedition navigation systems.

FCC Certified and Ready to Ship
FCC certification is not a detail — it is the difference between a product you can legally deploy in a commercial application and one that stays on your desk as a prototype.
Every RFOXiA module, including the MultiNav Pro+, carries full FCC certification. This means:
- Legal commercial deployment in the United States
- Eligibility for distribution through major electronics distributors
- Confidence that the RF design has been validated against regulatory emissions standards
- Reduced regulatory burden for products built with RFOXiA modules
When you are evaluating where to buy a GNSS module for a professional project, certification status matters as much as specifications. The MultiNav Pro+ delivers on both.
