GPS Module 1m Accuracy: Meet the MultiNav Pro+ GNSS Module
The GPS Module 1m Accuracy Standard Has Changed — Here's What That Means for Builders
If you've been searching for a GPS module with 1m accuracy that doesn't cost a fortune or require military-grade procurement paperwork, your search ends here. The RFOXiA MultiNav Pro+™ is a professional-grade GNSS module engineered for builders, drone operators, researchers, and IoT developers who demand precision location data at a price that doesn't break the bank.
Let's be direct: most modules on the market either give you mediocre accuracy at a low price or punish you with enterprise pricing for anything that performs at a professional level. The MultiNav Pro+ tears that trade-off apart. At just $49, it delivers sub-1.5-meter accuracy, an 18Hz fix rate, a 1-second first fix, and concurrent support for GPS, GLONASS, Galileo, and BeiDou — all packed into a 26mm × 22mm board powered by the latest u-blox MIA-M10Q chip.
This isn't marketing language. These are real specs backed by real engineering.
Why Precision GNSS Matters More Than Ever
Location data is the backbone of modern autonomous systems. Whether you're building a racing drone, a precision agriculture drone, a field research station, a wearable tracker, or a smart city sensor node — the quality of your GNSS module determines the quality of everything built on top of it.
Consider the difference between 5-meter accuracy and 1.5-meter accuracy in a real-world deployment:
- A drone returning to home at 5m accuracy might land 5 meters from its pad — potentially in an obstacle. At 1.5m, it lands close enough to matter.
- A field research station trying to map environmental sensor data needs the GPS coordinates to reflect exactly where data was collected, not an approximated zone.
- A precision agriculture system calculating variable-rate inputs needs sub-2-meter accuracy to prevent waste and crop damage.
- A tracking module on a vehicle or asset needs enough resolution to distinguish lanes of traffic or warehouse aisles.
When you're building for performance, the GPS module 1m accuracy tier isn't a luxury. It's a requirement. And the MultiNav Pro+ delivers it.
Inside the MultiNav Pro+: What Makes It Different
Powered by the u-blox MIA-M10Q
At the heart of the MultiNav Pro+ is the u-blox MIA-M10Q — one of the most capable low-power GNSS chipsets available for embedded applications. u-blox is widely regarded as the gold standard in professional GNSS silicon, trusted by automotive manufacturers, defense contractors, and precision agriculture OEMs worldwide.
The MIA-M10Q brings a new level of performance to a compact form factor. It supports simultaneous reception from all four major satellite constellations — GPS (USA), GLONASS (Russia), Galileo (EU), and BeiDou (China) — which means the module is never dependent on a single satellite network. In environments where one constellation has poor sky coverage, the others compensate. The result is a faster fix, more stable tracking, and better accuracy across the globe.
1.5-Meter Accuracy in a $49 Module
The MultiNav Pro+ achieves less than 1.5-meter accuracy under normal open-sky conditions. For developers hunting a true GPS module 1m accuracy class solution, this places it firmly in that tier — well beyond what generic consumer GPS modules deliver, and far more accessible than survey-grade RTK systems costing thousands.
The 18Hz fix rate is equally important. Most hobby-grade GPS modules update at 1Hz or 5Hz. At 1Hz, a drone traveling at 60 km/h covers 16.7 meters between position updates. At 18Hz, the same drone gets a position update every 0.9 meters of travel. That's not a marginal improvement — it's the difference between a smooth control loop and a jerky, dangerous one.
And with a 1-second first fix under warm start conditions, the MultiNav Pro+ is ready when you are. No sitting on the launch pad waiting for satellite lock.
Hardware Design: Built for Integration
Compact and Power-Efficient
At 26mm × 22mm, the MultiNav Pro+ is genuinely tiny. You can drop it onto a 250mm FPV frame, embed it in a wearable device, or attach it to a rover chassis without redesigning your build around the GPS module.
Power consumption sits at 25-30mA during active tracking — low enough to run comfortably from a small LiPo cell or regulated 3.3V supply for extended field deployments. This is the kind of figure that makes battery life calculations easy and field runtimes long.
The integrated high-gain chip antenna means there's no external antenna to attach, no coax cable to route, and no SMA connector to snap off during a rough landing. The antenna is part of the board, oriented for optimal sky-view reception.
Advanced RF Filtering
One of the design elements that separates the MultiNav Pro+ from cheap GNSS modules is its proprietary RF/microwave microstrip filter technology. GNSS signals are extraordinarily weak by the time they reach the surface — around -130 dBm. Any RF noise from nearby electronics — switching regulators, motor drivers, digital logic — can easily overwhelm them.
RFOXiA's RF design background informs every layer of the MultiNav Pro+'s layout. The microstrip filter is engineered to suppress out-of-band interference and maximize signal-to-noise ratio. In a noisy environment like a drone electronics bay, this is the difference between reliable lock and frustrating dropouts.
Connectivity: Built for Flexibility
The MultiNav Pro+ speaks the languages your project already uses. It supports both UART (TX/RX) and I2C (SCL/SDA) interfaces, giving you flexibility regardless of your microcontroller or flight controller architecture.
- UART is the standard interface for most flight controllers (Betaflight, ArduPilot, PX4) and is the highest throughput option for continuous position streaming at 18Hz.
- I2C allows daisy-chaining multiple devices on a shared bus — useful in sensor-dense IoT or research node deployments where GPIO pins are at a premium.
Voltage compatibility covers 1.8V and 3.3V logic levels, ensuring seamless connection to modern low-voltage microcontrollers, SBCs, and FPGA dev boards without level shifters.
This module was designed by engineers who build with hardware every day. The interface flexibility reflects that.
Software: Open Source and Developer-Ready
Open-Source C Driver Library
Every MultiNav Pro+ ships with access to a fully open-source C language library that implements the NMEA standard protocol commands. This is not a stripped-down sample — it's a production-ready driver designed to get you from unboxing to live GPS data in minutes.
Compatibility spans the full toolchain ecosystem:
- Arduino IDE — plug-and-play with standard library import
- PlatformIO — full support for embedded C/C++ projects
- Any C/C++ toolchain — the library is written in portable C, meaning it compiles cleanly across ARM, AVR, ESP32, STM32, and other targets
No proprietary SDK lock-in. No licensing fees. No black-box binary blobs. You get the source, you own the implementation, and you can modify it freely for your application.
u-center Software Support
Because the MultiNav Pro+ is built on the u-blox MIA-M10Q, it has full compatibility with u-center — u-blox's professional GNSS evaluation software. u-center gives you:
- Real-time satellite visualization — see exactly which satellites are in view, their signal strength, and elevation angles
- Live track logging — record and replay movement paths with full position data
- Module configuration — adjust fix rate, output messages, power modes, and constellation selection via a clean GUI
- Signal quality analysis — diagnose antenna placement and interference issues before they become field problems
- NMEA message inspection — view raw protocol output and verify your driver implementation
This is the same tool used by professional GNSS engineers at tier-1 OEM companies. It's available free from u-blox and works out of the box with the MultiNav Pro+ over UART.

Why FCC Certification Matters for Your Project
Every RFOXiA module — including the MultiNav Pro+ — carries FCC certification. This is not a minor detail.
FCC certification means the module has been tested by an accredited laboratory and confirmed to meet the electromagnetic emissions and interference standards required by US law. For product developers, this dramatically simplifies the compliance path for final products that incorporate the MultiNav Pro+. For individual builders deploying in the US, it means you're operating legal hardware.
For distributors and commercial resellers, FCC certification is typically a minimum requirement for stocking and selling RF hardware. The MultiNav Pro+ meets this bar out of the box.
Frequently Asked Questions
Q: Is 1.5m accuracy the same as a GPS module 1m accuracy spec? The MultiNav Pro+ achieves less than 1.5m CEP (Circular Error Probable) accuracy under normal open-sky conditions. In optimal conditions, real-world accuracy often improves further. For applications requiring sub-meter RTK accuracy, a differential correction source would need to be added — but for the vast majority of drone, IoT, and research applications, sub-1.5m is the practical GPS module 1m accuracy tier.
Q: Can I use this with ArduPilot or PX4 flight controllers? Yes. The UART interface is directly compatible with the GPS port on most popular open-source flight controllers. Standard NMEA output or u-blox binary protocol works natively.
Q: Does this work globally? Yes. The concurrent four-constellation support — GPS, GLONASS, Galileo, BeiDou — provides global coverage. There is no region where at least two constellations are unavailable.
Q: Can I run this from a 5V Arduino? The module operates at 1.8V or 3.3V logic levels. A 3.3V regulator or logic level converter is required when interfacing with 5V systems. This is standard practice for modern low-voltage GNSS hardware.
Q: Is there a quick start guide? Yes — every MultiNav Pro+ ships with a Quick Start Guide, and full documentation is available in the RFOXiA Club resources section.
