Sparkfun SparkPNT RTK Facet mosaic

The SparkPNT RTK Facet mosaic, crafted in Boulder, Colorado, USA, is a premier receiver designed for precise geolocation and surveying. Utilizing the advanced multi-band mosaic-X5 from Septentrio, this device offers centimeter-level accuracy with ease. Basic users can quickly get started, while advanced users will find it a versatile tool. With Real Time Kinematic (RTK) support, achieve 6mm-level fixes in under a minute. Connect via Bluetooth® to receive NMEA output on your phone or tablet, compatible with most GIS software.

The RTK Facet mosaic is perfect for a range of applications. Use it in GNSS Positioning mode for 40cm accuracy, or switch to RTK mode for precise 6mm measurements. It can function as a GNSS Base Station or an NTRIP Server, offering flexibility for various surveying and mapping tasks. The device also logs NMEA and RINEX data for post-processing, making it ideal for research and advanced positioning needs.

One of the standout features of the RTK Facet mosaic is its open-source design. You have full access to the electrical and mechanical design files, allowing for customization and easier maintenance over time. The device is powered by an ESP32 WROOM connected to a mosaic-X5 GNSS multi-band receiver, with a surveyor-grade L1/L2/L5 GNSS antenna under its dome. Programmed in Arduino, it can be tailored to meet specific requirements.

For those looking to build a DIY GNSS Reference Station, consider pairing the ESP32 with the ZED-F9P breakout. However, note that the RTK Facet mosaic is not intended for permanent outdoor mounting. For long-term installations, explore alternatives like the RTK mosaic-X5 or RTK Reference Station.
