GNSS Module Tindie: The MultiNav Pro+ Is the Precision Navigation Module Makers Have Been Waiting For
Find the Best GNSS Module on Tindie — 1.5m Accuracy, 18Hz Fix Rate, $49
If you've been searching for a professional-grade GNSS module on Tindie that actually delivers the accuracy, fix rate, and integration simplicity your projects demand — the search is over. The RFOXiA MultiNav Pro+™ is an FCC-certified precision GNSS module built for drone builders, IoT developers, robotics engineers, field researchers, and anyone who needs to know exactly where something is, in real time, without compromise.
At $49, it occupies a position in the market that simply didn't exist before: professional-grade navigation hardware at a price makers can actually afford.
This post covers everything you need to know — specs, use cases, integration details, software support, and why the MultiNav Pro+ stands apart from every other GNSS module available to the maker community today.
What Makes a GNSS Module Worth Buying?
Before diving into the MultiNav Pro+ specifically, it's worth establishing what separates a genuinely useful GNSS module from the flood of cheap GPS breakouts that litter the market.
Most low-cost GPS modules available to makers share the same fundamental limitations:
- Low fix rate: Typically 1Hz to 5Hz. That means one location update per second at best. For a drone moving at 60km/h, that's 16 meters of travel between updates. Completely inadequate for real-time control or precision tracking.
- Poor accuracy: Budget modules often advertise "2.5m CEP" accuracy but deliver far worse in practice due to poor antenna design, no multi-constellation support, and no hardware filtering.
- Single constellation: GPS only. No Galileo, no GLONASS, no BeiDou. Fewer satellites means slower fixes, weaker signals, and complete failure in signal-challenged environments.
- No ecosystem: A raw module with a datasheet and no software library, no GUI support, and no integration path.
The MultiNav Pro+ was designed to eliminate every single one of those compromises.
MultiNav Pro+™ — Full Specifications
The MultiNav Pro+ is built around the u-blox MIA-M10Q, one of the most advanced GNSS chips available for embedded applications. Here's what that means in practice:
| Specification | MultiNav Pro+ || |---|---| | GNSS Accuracy | < 1.5 meters CEP | | Fix Rate | Up to 18Hz | | First Fix Time | 1 second (hot start) | | Constellations | GPS, Galileo, GLONASS, BeiDou (concurrent) | | GNSS Chip | u-blox MIA-M10Q | | Antenna | Integrated high-gain chip antenna | | Interface | UART (TX/RX) and I2C (SCL/SDA) | | Operating Voltage | 1.8V and 3.3V | | Current Draw | 25–30mA | | Module Dimensions | 26mm x 22mm | | Certification | FCC Certified | | Price | $49 |
These are not aspirational specs. These are the actual tested, certified numbers from a module that has shipped to hundreds of customers across four Kickstarter campaigns.
1.5-Meter Accuracy and 18Hz Fix Rate — Why Both Numbers Matter
These two specifications work together. Accuracy tells you how close the reported position is to reality. Fix rate tells you how often that position is updated.
1.5-meter accuracy means that 50% of the time, your reported position is within 1.5 meters of your actual position. For most professional applications — drone waypoint navigation, asset tracking, field surveying, precision agriculture — this is the threshold where location data becomes genuinely actionable.
18Hz fix rate means 18 position updates per second. Consider what this enables:
- A drone flying at 100km/h moves approximately 1.5 meters between each 18Hz update. That's tight enough for real flight control loops.
- A racing drone at 150km/h moves just over 2 meters between updates — still far superior to anything a 5Hz or 10Hz module could deliver.
- A ground robot moving at walking speed gets sub-centimeter displacement between fixes — enough for precise path following.
For comparison: the most common budget GPS modules on the market operate at 1Hz. That means one update per second. At any meaningful speed, your position data is already stale before it's processed.
The MultiNav Pro+ doesn't make you choose between accuracy and speed. You get both.
Power-Efficient and Ultra-Compact Design
At 26mm x 22mm, the MultiNav Pro+ is compact enough to fit into virtually any form factor — from racing drone frames with minimal real estate, to wearable trackers, to compact IoT sensor nodes.
The 25–30mA current draw running a full concurrent multi-constellation fix is genuinely impressive. Most comparable modules draw significantly more power when operating all four constellations simultaneously. The u-blox MIA-M10Q architecture is optimized for low-power operation without sacrificing performance — which matters enormously for battery-powered deployments.
This combination — small size, low power, high performance — is why the MultiNav Pro+ fits into applications that other precision GNSS modules simply cannot.
Versatile Connectivity: UART and I2C Support
The MultiNav Pro+ supports both UART and I2C interfaces — the two most universal communication protocols in embedded development. This means you can connect it to virtually any microcontroller, development board, or SBC without adapters or protocol translation:
- Arduino (Uno, Mega, Due, Nano)
- ESP32 / ESP8266
- STM32 family
- Raspberry Pi and Pi Pico
- Teensy
- BeagleBone
- Any Linux SBC with UART/I2C
The dual-voltage support (1.8V and 3.3V) further expands compatibility, allowing direct connection to both modern low-voltage microcontrollers and legacy 3.3V systems without level shifting.
If your microcontroller has UART or I2C — and virtually all of them do — the MultiNav Pro+ is plug-and-play.
Open-Source Driver: Ready for Arduino IDE and Any Toolchain
One of the biggest hidden costs in hardware development is software integration time. A module that requires days of driver development before you can read a single GPS coordinate is a module that slows your project down.
The MultiNav Pro+ ships with a fully open-source C language driver library that includes:
- NMEA standard protocol parsing — the universal language of GNSS data, already decoded for you
- Arduino IDE compatibility — import the library, initialize the module, start reading coordinates in minutes
- Compatibility with any C/C++ toolchain — STM32CubeIDE, PlatformIO, Eclipse, GCC bare-metal, anything
- Example code for common applications — position reading, speed calculation, altitude, satellite count
This isn't a bare datasheet and a block diagram. It's a real, working software library that makes first-light integration take minutes, not days.
For developers who want even faster firmware development, the MultiNav Pro+ is fully supported within the RFOXiA AI Firmware Builder — describe your application in plain language, get complete production-ready firmware back. Available inside RFOXiA Club with a free account.
U-Center Software: Powerful GUI for Configuration and Evaluation
Because the MultiNav Pro+ is built on the u-blox MIA-M10Q, it is fully compatible with u-center — u-blox's professional GNSS evaluation and configuration software.
u-center gives you:
- Satellite visualization — see every satellite in view, signal strength, constellation breakdown
- Real-time position tracking — watch your position update on a live map at full 18Hz rate
- Quick configuration — set fix rate, enable/disable constellations, configure power modes without writing a single line of code
- Powerful logging — record and replay GNSS sessions for analysis
- NMEA and UBX protocol support — full access to raw and processed GNSS data streams
- Flexible user interface — dockable windows, configurable layouts, professional-grade tools
This is the same software used by professional GNSS engineers evaluating u-blox modules for industrial and automotive deployment. It is available free from u-blox, and it works directly with the MultiNav Pro+ over UART.
For prototyping, testing, and debugging, u-center dramatically accelerates development and gives you visibility into your GNSS performance that no budget module can match.

Why the MultiNav Pro+ Is the Right GNSS Module for Your Next Project
Let's be direct about where this module sits in the market.
Below it: Budget GPS breakouts at $5–15. 1Hz fix rate, 2.5m+ accuracy (real-world, not datasheet), single constellation, no software support, no certifications. Fine for learning. Inadequate for serious projects.
Above it: Industrial and survey-grade GNSS receivers at $500–$5,000+. Centimeter accuracy, RTK support, industrial enclosures. More than most makers, drone builders, and IoT developers will ever need — and completely inaccessible at that price point.
The MultiNav Pro+ occupies the gap between these extremes: professional accuracy and fix rate, maker-accessible price, FCC certified, with complete software support and ecosystem integration. There is genuinely nothing else in this position.
At $49, with an 18Hz fix rate, 1.5-meter accuracy, concurrent four-constellation support, u-blox MIA-M10Q at its core, and a complete open-source driver library, the MultiNav Pro+ is not a budget compromise. It is a deliberate design decision to give serious builders serious tools at prices that don't require a corporate purchase order.
FCC Certification: What It Means and Why It Matters
FCC certification is not just a compliance checkbox. It means the MultiNav Pro+ has been tested by an accredited laboratory and confirmed to operate within legal RF emission limits. It means you can deploy it in real products, sell products containing it, and integrate it into commercial applications without regulatory risk.
For a GNSS module available to makers at $49, FCC certification is exceptional. Most modules at this price point are uncertified — which creates real legal exposure if you integrate them into a product intended for sale. The MultiNav Pro+ is certified. It's ready for your product, not just your prototype.
