GPS Accuracy 1 Meter Module: The MultiNav Pro+ GNSS Module That Changes Everything
Achieve Sub-1.5m GPS Accuracy 1 Meter Class Performance in a 26mm Module
If you have ever tried to build a drone tracking system, deploy a precision agriculture sensor, or develop a navigation-critical IoT device, you already know the pain: finding a GNSS module that delivers true GPS accuracy 1 meter class performance without costing a fortune or requiring a master's degree to integrate is nearly impossible at the maker and developer level.
Most commodity GPS modules claim accuracy figures that fall apart the moment your platform starts moving. They advertise circular error probable (CEP) values measured under ideal, static, open-sky conditions — then deliver 5 to 10 meters of drift the moment you attach one to a moving drone or a field sensor node.
The MultiNav Pro+ GNSS Module from RFOXiA was built to end that compromise. With a verified accuracy of less than 1.5 meters, an 18Hz fix rate, concurrent four-constellation support, and a footprint of just 26 x 22mm, it is the most capable location module available to hardware developers at this price point. And it ships ready to integrate today.
This article covers everything you need to know: the technical specifications, how the module achieves its performance, who it is built for, how it fits into the RFOXiA ecosystem, and why it represents a genuine step forward for anyone who needs GPS accuracy 1 meter class precision in a professional-grade, developer-accessible package.
Why GPS Accuracy 1 Meter Class Performance Actually Matters
Location accuracy in hardware development is not a vanity metric. The difference between 1.5 meters and 10 meters of accuracy is the difference between a drone that lands exactly where you commanded and one that drifts into an obstacle. It is the difference between a precision agriculture system that maps your field at row-level resolution and one that smears data across several planting beds. It is the difference between research-grade data and noise.
For the applications that RFOXiA hardware developers are building — autonomous drones, robotic platforms, environmental sensor networks, smart city nodes, and precision tracking systems — GPS accuracy 1 meter class performance is not optional. It is the baseline requirement.
And yet, the hardware available at sub-$100 price points has historically failed to deliver it reliably. The MultiNav Pro+ closes that gap.
The Engine Inside: u-blox MIA-M10Q
The MultiNav Pro+ is powered by the u-blox MIA-M10Q, one of the most advanced low-power GNSS chips available on the market today. u-blox is the industry standard for serious GNSS integration — their chips are found in everything from professional survey equipment to automotive navigation systems.
The MIA-M10Q brings that same pedigree to a compact, power-efficient package. It supports concurrent reception from four global satellite systems:
- GPS (United States)
- Galileo (European Union)
- GLONASS (Russia)
- BeiDou (China)
Concurrent multi-constellation support is critical. When your module can simultaneously receive signals from all four systems, it has access to dramatically more satellites at any given moment — which means faster first fix times, more robust signal in challenging environments (urban canyons, tree cover, reflective surfaces), and fundamentally better accuracy. Single-constellation modules are forced to work with whatever GPS satellites happen to be overhead. Multi-constellation modules have the entire global infrastructure working for them at once.
This is one of the core reasons the MultiNav Pro+ achieves GPS accuracy 1 meter class performance where single-constellation competitors at similar price points cannot.
Performance Specifications: What the Numbers Mean
Let's break down the specifications that matter most for developers:
Accuracy: Less Than 1.5 Meters
This is the headline specification. In practical terms, GPS accuracy 1 meter class performance at 1.5m CEP means that 50% of all position readings fall within a 1.5-meter circle of the true position. For most applications — drone landing, asset tracking, environmental node placement, agricultural mapping — this is sufficient for professional-grade work without RTK correction.
Fix Rate: 18Hz
Most consumer and low-cost GNSS modules update at 1Hz or 5Hz. The MultiNav Pro+ updates at 18 times per second. This is not a cosmetic improvement — it is the difference between smooth, real-time tracking of a fast-moving drone and a blocky, interpolated position estimate that lags behind reality. At 18Hz, your control system, your logging system, and your display all receive position data fast enough to react in real time.
First Fix: 1 Second
Time to first fix (TTFF) determines how quickly your device becomes operational after power-on. A 1-second first fix is exceptional — your drone, robot, or sensor node is location-aware almost instantaneously.
Power Consumption: 25-30mA
For a module this capable, 25-30mA is highly efficient. This makes it practical for battery-powered and field-deployed applications where power budgeting matters.
Compact and Efficient: Built for Real-World Integration
At 26 x 22mm, the MultiNav Pro+ is designed to fit into constrained designs without compromise. Whether you are building a micro drone, a compact wearable tracker, a field-deployed IoT node, or a custom robotics platform, this form factor integrates cleanly without dominating your PCB layout.
The integrated chip antenna means you do not need to design, tune, or source a separate antenna — the module is complete as shipped. This eliminates a major source of design complexity and RF performance variability that plagues projects using bare GNSS chips.
The combination of high performance and compact design is intentional. RFOXiA's design philosophy, driven by founder Moamen Mohamed's deep expertise in PCB design and RF engineering, prioritizes building professional-grade capability into the smallest practical footprint. The MultiNav Pro+ reflects that directly.
Versatile Connectivity: UART and I2C Support
Hardware integration flexibility is a practical priority. The MultiNav Pro+ supports both UART (TX/RX) and I2C (SCL/SDA) interfaces, giving developers the freedom to connect using whichever bus fits their existing system architecture.
- UART is ideal for high-throughput data streaming — particularly useful when you need to capture all 18Hz of position data with minimal latency
- I2C allows the module to share a bus with other sensors, saving GPIO pins in sensor-dense designs
Voltage compatibility covers both 1.8V and 3.3V logic levels, making the module compatible with modern low-voltage microcontrollers and single-board computers without level shifting.
This level of interface flexibility is characteristic of a module designed by engineers who actually build with hardware, not just specify it.
Open Source Driver: Integrate in Minutes
One of the most underappreciated aspects of the MultiNav Pro+ is the software support. The module ships with a fully open-source C language driver library that implements standard NMEA protocol commands. The library is designed for straightforward import into Arduino IDE and compatible with virtually any other toolchain — PlatformIO, STM32CubeIDE, Zephyr, or custom embedded C environments.
For developers who want GPS accuracy 1 meter class performance without writing low-level GNSS parsing code from scratch, this is significant. You get a fully functional GNSS integration with clean, readable, and modifiable source code — ready to adapt to your specific application.
The open-source approach also aligns with RFOXiA's broader philosophy of developer empowerment. This is hardware you can understand end-to-end, customize freely, and build production systems on with confidence.

u-Center Software: Professional Visualization and Configuration
Beyond firmware development, the MultiNav Pro+ is compatible with u-blox u-Center software — the industry-standard desktop GUI for GNSS module evaluation, configuration, and testing.
u-Center gives you:
- Satellite visualization — see exactly which satellites your module is tracking and their signal strength in real time
- Position tracking — watch your position update on a live map as you move
- Flexible configuration — adjust fix rate, constellation selection, NMEA output format, and power modes without writing a single line of code
- Powerful data logging — capture raw NMEA streams and post-process them for research and validation
- Protocol analysis — deep inspection of UBX and NMEA messages for development and debugging
For developers validating a new design, u-Center is invaluable. It lets you confirm that your module is receiving expected satellite constellations, verify your accuracy figures under real-world conditions, and tune the configuration for your specific application — all through a graphical interface.
This professional toolchain compatibility is another indicator that the MultiNav Pro+ is a serious tool, not a toy module.
Who This Module Is Built For
The MultiNav Pro+ is engineered for builders, researchers, and developers who refuse to compromise on location accuracy. Specific use cases where GPS accuracy 1 meter class performance delivers real value:
Drone Builders and FPV Pilots
Autonomous return-to-home, precision hover, waypoint navigation, and payload delivery all depend on accurate, high-rate position data. At 18Hz and 1.5m accuracy, the MultiNav Pro+ gives your flight controller the data it needs to perform reliably.
Robotic Systems
Ground robots navigating outdoor environments need position updates fast enough to correct course in real time. The 18Hz fix rate makes the MultiNav Pro+ suitable for control loops that would overwhelm a standard 1Hz or 5Hz GNSS module.
IoT Sensor Networks and Environmental Monitoring
Deploying a distributed sensor network requires knowing exactly where each node is located. When that location data is used to validate data quality (as in the RFOXiA data monetization network), GPS accuracy 1 meter class precision is essential for ensuring nodes are where they claim to be.
Precision Agriculture
Field mapping, variable-rate application, and crop health monitoring at the row or individual plant level require sub-2-meter positioning. The MultiNav Pro+ delivers this without the cost of RTK systems.
Asset Tracking and Fleet Management
Tracking high-value assets in real time requires both accuracy and update rate. Whether you are monitoring construction equipment, livestock, or shipping containers, the MultiNav Pro+ gives you reliable, fast, precise position data.
Wearables and Personal Navigation
Compact form factor and low power consumption make the MultiNav Pro+ suitable for wearable applications where size and battery life are constraints.
Research and Education
Universities and research teams working on navigation, geospatial data, or environmental monitoring need hardware they can trust and software they can inspect. The open-source driver and u-Center compatibility make the MultiNav Pro+ a transparent and verifiable research tool.

Advanced RF Signal Filtering: The Hidden Differentiator
One of the less visible but technically significant features of the MultiNav Pro+ is its proprietary RF/microwave microstrip filter technology. GNSS signals are extraordinarily weak by the time they reach your receiver — the entire global positioning system depends on your module being able to extract valid navigation data from signals that have traveled thousands of kilometers from orbit.
Interference from nearby electronics, cellular signals, WiFi, and even harmonics from your own system's oscillators can degrade GNSS performance significantly. In real-world deployments — a drone with a camera, an IoT node in an industrial environment, a tracker mounted near a vehicle's electronics — interference is the norm, not the exception.
The microstrip filter design in the MultiNav Pro+ specifically addresses this. By minimizing out-of-band interference before it reaches the receiver, the module maintains its GPS accuracy 1 meter class performance in environments where lesser modules would see significant degradation. This is a direct consequence of RFOXiA's RF engineering expertise applied at the module design level.
FCC Certified and Ready to Ship
For developers building commercial products, FCC certification is not optional — it is the gate to market. The MultiNav Pro+ carries full FCC certification, which means:
- You can legally integrate it into products sold in the United States
