RTK Facet - set with GNSS receiver

Description

SparkFun RTK Facet is a precise geolocation and measurement device that allows measurement with an accuracy of centimeters. Launching basic functions and using RTK Facet is extremely simple. The device also offers many advanced features, including full calibration via NGS, making it a versatile tool for both beginners and advanced users.

The module can be paired with a phone via Bluetooth, which serves as a radio connection. This allows the phone to provide correction data and receive NMEA data from the device. This solution is used in professional measuring devices. RTK Facet works with popular GIS software for Android and iOS. Offers support for SW Maps Android/iOS, Field Genius, SurvPC, Survey Master, Vespucci, QGIS, QField and others that support NMEA via Bluetooth.

The device is equipped with an antenna of measurement class L1/L2, which affects the precision of measurements. RTK Facet can operate in four modes:

• GNSS positioning (~30 cm accuracy): Also called "Rover", this mode allows you to receive GNSS signals from four constellations and calculate your position with an accuracy of approximately 30 cm.
• GNSS positioning with RTK (1.4 cm accuracy): "Rover with RTK Fix" mode allows you to receive signals from the L1/L2 antenna and correction data from the base station, which allows you to achieve an accuracy of 1.4 cm.
• GNSS Base Station: In "Base Station" mode, RTK Facet acts as a base station and transmits correction data to the "Rover" station, allowing you to obtain a precise position.
• GNSS base station with NTRIP server: In this mode, the device can act as a GNSS base station with NTRIP server, enabling more advanced operations.

RTK Facet is the perfect tool for professionals who need precise geolocation measurements. Thanks to easy access to the project and advanced configuration options, it is a versatile and flexible device.
