F01GNSS receiver & patch antenna

Measure position and time from satellite signals.

Manufacturers & products

A GNSS accessory supplies position, speed and time. It does not by itself add autonomous navigation or a dependable return function; those behaviors depend on the flight controller, firmware and installation.

American sourcing options appear first. A U.S. company or distributor label does not establish U.S. manufacturing. The origin notes identify the specific evidence and any limits.

SparkFun

SAM-M10Q GPS breakout (GPS-21834)

US-company carrier board around u-blox's GNSS antenna module, exposing UART and I2C. [2][1]

U.S. company

SparkFun identifies Niwot, Colorado operations. The reviewed GPS-21834 listing does not make a product-specific US assembly claim; the u-blox module is a separate upstream component. [2][1]

Program / application

5-inch integration candidate; board is 3.3 V, not a generic 5 V GPS accessory [2][1]

Company location: Niwot, Colorado, USA

Online catalog / ordering

Official product page provides a catalog or inquiry route; verify current stock, revision, firmware and connectors before ordering.

u-blox

SAM-M10Q

Surface-mount GNSS module incorporating an antenna and RF front end. [3][4]

International supplier

u-blox identifies headquarters in Thalwil, Switzerland. This is company location, not proof of wafer, packaging or module-assembly country. [3][4]

Program / application

Upstream module for a custom carrier; not a complete wired flight-controller accessory [3][4]

Company location: Thalwil, Switzerland

MATEKSYS

M10Q-5883

Compact GNSS and compass carrier with UART and I2C interfaces. [5]

U.S. connection unverified

The reviewed product page does not establish corporate domicile or manufacturing country. No US production or US-company claim is made. [5]

Program / application

5-inch GNSS integration candidate; compass placement is especially constrained [5]

Manufacturer inquiry

Use the manufacturer's product and reseller route to confirm authentic hardware and the current revision.

Product scope & qualifications

Manufacturer warns of counterfeit M10Q-5883 units; source through a verifiable channel.
Listing calls the connector JST-GH but gives a conflicting pitch; verify the connector drawing before ordering a harness.

What remains unverified

These examples use the same broad u-blox M10 technology family; supplier count is not silicon-vendor diversity.
No product-specific US manufacturing claim was established for the shortlisted complete GNSS boards.
Comparable position-error tests on this airframe were not available.

Where it comes from

A company address is shown separately from a published factory location. Request the manufacturing site and lot traceability for the exact part when sourcing.

What to compare

Receiver versus carrier
Separate chip/module voltage and dimensions from the complete board's connectors and regulator.
Constellation configuration
Concurrent GNSS reception affects acquisition and available update modes.
Update rate · Hz
Check the rate with the intended constellation set, not the fastest single-system headline.
Accuracy conditions · m
Demand test definition and environment; satellite count is not an accuracy guarantee.
Supply and I/O · V
Verify receiver input, logic voltage and regulator requirements independently.
Interface and firmware
Confirm UART protocol, baud rate, supported messages and FC driver.
Antenna installation
Provide sky view and separation from interference sources and conductive shielding.
Compass and backup
Compass alignment, magnetic interference and backup power are separate integration decisions.

Selection & integration notes

Treat the SparkFun carrier and its u-blox module as two supply-chain layers, not independent GNSS chip alternatives.
Check FC support and electrical levels before choosing between an evaluation breakout and a dedicated flight accessory.
A compass placed next to high-current wiring may be less useful than a well-installed GNSS-only module.
