RTK Express Plus Kit - a set with a GNSS receiver and antenna

Description

Set with GNSS RTK Express Plus receiver, L1/L2 antenna and accessories, including cables, USB power supply and a convenient carrying case. It allows you to get centimeter-level global positioning measurements using GNSS RTK.

RTK Express Plus is a GNSS receiver designed for positioning with high accuracy at the centimeter level. Perfect for measurements, autonomous vehicles and data recording. It is a pre-programmed device that can also be used for autonomous driving, navigation, asset tracking and any other application where the device can connect to the GNSS system. It has a built-in IMU to combine real-time GNSS tracking with advanced sensor fusion. The result is accurate positioning, even if GNSS gets lost in tunnels, garages, etc. Out of the box, the RTK Express Plus can be used with a correction source to create an RTK system with 14mm horizontal positioning accuracy. Built-in Bluetooth® connectivity via WROOM ESP32 allows the user to use RTK Express Plus with the selected application on a phone or tablet. The built-in battery allows for over five hours of use in the field and is compatible with popular USB power banks.

RTK Express Plus can be used in two modes:

• GNSS positioning (accuracy up to 30 cm) - the device receives L1/L2 signals, and the GNSS receiver gives the width, length and height with an accuracy of about 300 mm
• GNSS positioning with RTK (1.4 cm accuracy) - the device receives L1/L2 signals from the antenna and correction data from the base station

The kit includes the L1/L2 antenna, adapters, cables and the charger needed to use GNSS. Full documentation with examples of use is available on the product page.
