FCC Certified GPS Module That Redefines Precision Navigation
The FCC Certified GPS Module Built for Builders Who Demand More
When your project depends on knowing exactly where it is — not approximately, not close enough, but exactly — the module you choose makes or breaks everything. Whether you are guiding an autonomous drone through a complex flight path, tracking fast-moving assets in real time, building a precision agriculture system, or developing a next-generation wearable device, your GNSS module is the foundation your entire application rests on.
The MultiNav Pro+™ Accurate GNSS Module from RFOXiA is the FCC certified GPS module engineered for that standard. With 1.5-meter accuracy, an 18Hz fix rate, concurrent multi-constellation support, and a compact form factor of just 26mm x 22mm, this module delivers professional-grade navigation performance at a price point accessible to every serious developer.
This guide covers everything you need to know about the MultiNav Pro+ — what it does, how it works, who it is built for, and why it stands apart from every other option in its class.
Why FCC Certification Matters More Than You Think
Before diving into specifications, it is worth understanding why FCC certification is not just a bureaucratic checkbox — it is a meaningful technical and commercial credential.
The Federal Communications Commission (FCC) tests and certifies RF-emitting devices to ensure they operate within defined frequency bands, at defined power levels, without causing harmful interference to other devices or infrastructure. A module that carries FCC certification has been through independent laboratory testing and has passed a rigorous review process.
For developers and engineers, FCC certification means:
- Legal deployment in the United States — non-certified modules cannot legally be incorporated into commercial products sold in the US market
- Interference compliance — the module will not disrupt other electronics in close proximity, which is critical in multi-sensor systems like the RFOXiA ecosystem
- Distributor eligibility — major distributors including DigiKey and Mouser require FCC certification for marketplace listing
- Customer confidence — enterprise buyers, academic institutions, and commercial operators require certified components
- Integration safety — in drone and robotics applications, interference from uncertified modules can cause catastrophic failure
The MultiNav Pro+ carries FCC certification, making it one of the few high-performance FCC certified GPS modules available at this price point with these specifications. Every module in the RFOXiA product line carries FCC certification — a deliberate choice that reflects the company's commitment to professional-grade hardware accessible to every builder.
MultiNav Pro+™ Specifications: What the Numbers Mean
The MultiNav Pro+ is powered by the u-blox MIA-M10Q — one of the most capable GNSS chipsets available for embedded applications. Here is what the core specifications actually mean for your project.
1.5-Meter Accuracy
Most low-cost GPS modules advertise accuracy in the 2.5 to 5-meter range. In practice, under real-world sky conditions with multipath interference, that number climbs to 5 to 10 meters or more. The MultiNav Pro+ achieves a consistent 1.5-meter CEP (Circular Error Probable) — meaning 50% of position readings fall within 1.5 meters of the true location, and the distribution is tight enough for demanding applications.
For drone navigation, autonomous vehicle guidance, precision mapping, or asset tracking, that difference between 1.5 meters and 5 meters is the difference between a usable system and an unreliable one.
18Hz Fix Rate
Standard GPS modules update their position output at 1Hz — once per second. Higher-end modules offer 5Hz or 10Hz. The MultiNav Pro+ delivers up to 18Hz — eighteen position updates per second.
Why does this matter? For any fast-moving platform — a racing drone, an FPV aircraft, a ground vehicle, a high-speed tracking application — a 1Hz update rate means your system is navigating on data that is already a full second old. At 30 meters per second (a moderate drone speed), that is 30 meters of stale data. At 18Hz, you are working with position data less than 56 milliseconds old.
This fix rate is what makes the MultiNav Pro+ genuinely useful for dynamic applications that commodity modules simply cannot serve.
First Fix in 1 Second
TTFF — Time to First Fix — determines how long your system waits at power-on before it has a valid position. Many modules require 30 seconds to several minutes for cold start acquisition. The MultiNav Pro+ achieves first fix in approximately 1 second under good sky conditions, dramatically reducing the startup delay in deployed systems.
Concurrent Multi-Constellation GNSS: Why It Matters
GPS is one satellite navigation system. It is also an American system, which means its satellite geometry is optimized for coverage over North America and may offer fewer visible satellites in other regions. Real-world GNSS environments are not ideal — buildings, terrain, and atmospheric conditions all affect satellite signal availability.
The MultiNav Pro+ simultaneously receives signals from four independent satellite constellations:
- GPS — US system, 31 operational satellites
- GLONASS — Russian system, 24 operational satellites
- Galileo — European system, 30+ operational satellites
- BeiDou — Chinese system, 35+ operational satellites
Combined, this gives the MultiNav Pro+ access to over 120 navigation satellites at any given moment. More satellites in view means better geometric diversity (DOP — Dilution of Precision), which directly translates to better positional accuracy and reliability.
In urban canyons, partially obstructed environments, or challenging terrain where only a subset of satellites are visible, multi-constellation support is the difference between getting a fix and getting nothing.
Compact Design Without Compromise
At 26mm x 22mm, the MultiNav Pro+ is engineered to integrate into space-constrained applications without requiring external antennas or complex RF layout work. The integrated chip antenna provides optimal signal reception within this compact footprint.
Power consumption is 25-30mA during active tracking — efficient enough for battery-powered systems and deployments where power budget is a constraint. This makes the MultiNav Pro+ viable for wearables, field research instruments, small autonomous vehicles, and sensor nodes where every milliamp matters.
The combination of compact size and low power draw makes this module genuinely deployable across a broader range of applications than larger, power-hungry alternatives.
Interface Flexibility: UART and I2C
The MultiNav Pro+ supports both UART (TX/RX) and I2C (SCL/SDA) interfaces, covering the two most common embedded communication protocols. This means integration with virtually any microcontroller, SBC, or development platform — STM32, ESP32, Arduino, Raspberry Pi, Teensy, Nordic nRF series — requires no adapter hardware or custom interface circuitry.
Voltage compatibility spans 1.8V and 3.3V logic levels, eliminating the need for level shifters in most modern embedded designs.
Open Source Driver: Firmware Development Without the Pain
One of the most underrated aspects of the MultiNav Pro+ is the fully open-source C language driver library included with the module. The library implements the NMEA standard protocol — the universal language of GNSS data — and is structured for immediate import into Arduino IDE or any modern IDE toolchain.
For developers who want to go further, RFOXiA's AI Firmware Builder platform (integrated into RFOXiA Club) allows you to describe your GNSS application in plain language and receive production-ready firmware with complete source code. Projects that would have taken weeks of driver development and protocol parsing can be up and running in hours.
This is not just a module — it is a module with an ecosystem behind it. Check out the RFOXiA Accurate GNSS Module product page to explore the full documentation and resources available.
U-Center Software: Professional Visualization and Configuration
Because the MultiNav Pro+ is powered by the u-blox MIA-M10Q, it is fully compatible with u-center — u-blox's professional GNSS evaluation and configuration software.
u-center provides:
- Satellite visualization — see every satellite the module is tracking, with signal strength, elevation, and azimuth
- Real-time position tracking — live map display of position fixes
- Configuration interface — adjust fix rate, output protocols, power modes, and constellation selection without writing a line of code
- Data logging — record raw GNSS data for post-processing and analysis
- Protocol analyzer — inspect raw NMEA and UBX protocol output
For research applications, system characterization, and production testing, u-center access turns the MultiNav Pro+ into a complete professional GNSS development environment. This is a capability set normally associated with GNSS evaluation kits costing several times the price of this module.
Advanced RF Signal Filtering
One feature that separates professional GNSS modules from commodity hardware is RF front-end quality. GNSS signals are inherently weak — they arrive at Earth's surface with a power level far below the noise floor in typical urban electromagnetic environments. Any interference in the signal path degrades accuracy and can cause complete loss of fix.
The MultiNav Pro+ incorporates proprietary RF/microwave microstrip filter technology that attenuates out-of-band interference before it reaches the GNSS receiver core. The result is cleaner signal acquisition, better sensitivity, and more reliable fix maintenance in challenging RF environments — near cellular towers, WiFi infrastructure, industrial equipment, or other wireless systems.
This filtering is designed into the PCB layout at the RF level — it is not a software correction or post-processing fix. It is real hardware performance that shows up in real-world deployments.
Who Is the MultiNav Pro+ Built For?
The MultiNav Pro+ is designed for any application where location accuracy, update speed, and reliable signal acquisition are non-negotiable. Core use cases include:
