About the Facet FP

The Facet FP is a high-precision GNSS device built around a modular system of receivers, designed to be entirely repairable and future-proof in addition to a powerful positioning device.

Available in 7 different configurations, models arrive fully assembled with your chosen module inside, ready to be put to work and deliver modern multi-frequency RTK positioning at an accessible price point.

Future-proofing GNSS.

We believe users should have total control over the devices they own. These receivers are repairable, user-upgradeable, and use open-source firmware. With five minutes and a Philips head screwdriver, the FP can be opened up and the module can be fully switched out.

Packed with modern features:

Capable of L1/L2/L5/E6 reception, with Galileo HAS support on the FPL and FPL-T.
MFi certified, ensuring compatibility with iOS devices.
Enclosed high-powered 915MHz 1W LoRa radio.
IP67 rated cast-aluminum housing with a reinforced dome.
Affordable and competitive price point when compared to similar devices.
Sub-centimeter horizontal accuracy when receiving RTK corrections across all models.
Internal battery with 24-50 hours of runtime, depending on the module inside.

Included in the Box

SparkPNT FP Device
Hard-Sided Carrying Case
Antenna Thread Adapter
Wall Adapter & Charging Cable
915MHz LoRa antenna
4 Multicolored rubber gaskets

A device built to last.

All models are contained in our robust cast-aluminum housing, with an internal structure designed for easy compatibility with our Flex system of GNSS engines.

How does the Facet FP work?

The FP models are differentiated by the GNSS engine inside that contains the GNSS receiver. Each FP model comes fully assembled with the chosen module, ready to be turned on and put to work.

If a new GNSS receiver gets released down the road or you decide that you want something different out of your equipment, you don’t have to buy a whole new device — just a new module.

Go the distance with LoRa

The Facet FP has an internal high power 1W LoRa radio built in, and comes with an external antenna that screws right into the bottom of the device.

The included carrying case has a custom compartment for the antenna, so no extra accessories are needed for long-range radio communication.

FAQs

Please read our FAQs page for more general help.

Is assembly required for the Facet FP?

Great question, your Facet FP will be shipped to you fully assembled based on which model you choose. If you later decide to upgrade or switch the GNSS engine inside of your Facet FP then there will be a small amount of assembly.

Watch our video on how to switch out your GNSS engine.

When will new GNSS Engine options be available?

Short answer: It depends.

It depends on when new GNSS technology provides meaningful advantages.

The Facet FP currently supports three GNSS Engine options with the follow GNSS Modules:

Quectel LG290P
u-blox ZED-X20P
Septentrio mosaic-X5

These engines were selected because each offers a distinct combination of performance, features, and price point. Our goal isn't to offer as many GNSS Engine options as possible—it's to offer options that solve different customer needs.

As new GNSS modules become available, we continually evaluate them for inclusion in the Facet FP. However, we likely won't introduce a new GNSS Engine unless it provides a meaningful benefit over existing options, such as:

Improved positioning performance
New capabilities or features
Better power efficiency
Enhanced signal tracking
A significantly different price-to-performance profile

If a future GNSS module offers compelling advantages, we'll certainly evaluate it for inclusion in the Facet FP lineup.

Is my warranty void if I open my Facet FP to make an upgrade?

No, as long as there are no other modifications made to the device your warranty will stay intact.

What is Galileo High Accuracy Service (HAS)?

Galileo High Accuracy Service (HAS) is a free satellite-delivered correction service that helps compatible GNSS receivers improve positioning accuracy.

The SparkPNT FPL versions support Galileo HAS, allowing users to take advantage of this modern correction service alongside traditional RTK workflows.

Watch our video guide to learn more about Galileo HAS and how it can be used in your applications.
