Product Overview

Designed and manufactured in Boulder, Colorado, USA, and utilizing the multi-band mosaic-X5 from Septentrio, the SparkPNT RTK Facet mosaic is the top-of-the-line receiver for high-precision geolocation and surveying needs. It’s incredibly easy for basic users to get up and running; for advanced users, the RTK Facet mosaic is a flexible and powerful tool. With just the press of a button, the RTK Facet mosaic is the fastest way to take centimeter-grade measurements. With Real Time Kinematic (RTK) support, 6mm-level fixes are less than a minute away. Connecting your phone to the RTK Facet mosaic over Bluetooth® lets your phone or tablet receive the NMEA output and work with most GIS software programs. This is exactly how $10,000 surveying devices have been operating for the past decade—we just made it faster, more precise, and much more economical.

The RTK Facet mosaic works with common GIS software for Android, iOS, and Windows, including SW Maps Android / iOS, Field Genius, SurvPC, Survey Master, Vespucci, QGIS, QField, and any GIS software that supports NMEA over Bluetooth.

Under the SparkPNT RTK Facet mosaic hood is an ESP32 WROOM connected to a mosaic-X5 GNSS multi-band receiver and various peripheral hardware (LiPo fuel gauge, microSD, etc.). Additionally, housed under the RTK Facet mosaic dome is a surveyor-grade L1/L2/L5 GNSS antenna. The RTK Facet mosaic is programmed in Arduino and can be tailored by you to fit your needs.

This device can be used in a variety of modes:

  • GNSS Positioning (~40cm accuracy) - also known as Rover
  • GNSS Positioning with RTK (6mm accuracy) - also known as Rover with RTK Fix
  • GNSS Base Station
  • GNSS Base Station NTRIP Server

In addition to supplying position data, the RTK Facet mosaic can log NMEA and RINEX for post-processing, making it ideal for research and advanced positioning applications.

The RTK Facet mosaic is an open-source hardware product, meaning you can fully obtain, view, and modify the electrical and mechanical design files. This allows for easier maintenance and repair over time.

Important:The SparkPNT RTK Facet mosaic is not designed for permanent outdoor mounting. Please use the RTK mosaic-X5 or the RTK Reference Station for installations that require long-term exposure. For a DIY solution, the ESP32 attached to our ZED-F9P breakout is a great alternative. See our How to Build a DIY GNSS Reference Station tutorial for more information.
Note: This product is identical to the retired SparkPNT RTK Facet mosaic L-Band. The name was changed due to the upcoming sunset of the PointPerfect L-Band service, which is scheduled to end on December 31, 2025.

Versatile Operating Modes

Rover Mode

The RTK Facet mosaic receives multi-band GNSS (L1/L2/L5) from GPS, GLONASS, Galileo, and BeiDou to quickly achieve RTK float and fix (typically within 60 seconds when using corrections like PointPerfect). It outputs standard 4 Hz NMEA data over Bluetooth®, delivering approximately 10–60 mm horizontal accuracy—far exceeding standard GPS performance.

Base Station Mode

When mounted in a fixed location, the RTK Facet mosaic performs a short survey (typically 60–120 seconds) and then transmits RTCM correction data from its radio port. This stationary Base works with a Rover unit to enable ~10 mm positioning accuracy by continuously sending correction data.

NTRIP Server (Base Mode)

In this mode, the RTK Facet mosaic operates as a GNSS base station that streams RTCM correction data to an NTRIP caster over the internet. This allows multiple Rover devices to receive real-time corrections remotely, enabling centimeter-level accuracy without a direct radio link.

Sophisticated anti-jamming and spoofing.

Septentrio’s cutting-edge cybersecurity technology makes the Facet mosaic impervious to network attacks and gives you peace of mind with your data accuracy and security.
