RTK Surveying Kit - kit with GNSS receiver and antenna

Description

Set with GNSS RTK Surveyor 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 Surveyor is a GNSS receiver designed for positioning with high accuracy on 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. Can be used as 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 Surveyor with the selected application on a phone or tablet, and the battery allows for over four hours of use in the field and is compatible with popular USB power banks.

RTK Express can be used in four 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
• GNSS base station - the device is mounted e.g. on a tripod and begins to send correction data via a radio or Internet link
• NTRIP server of the GNSS base station - the device is mounted in a partially or permanently fixed position and connects via Wi-Fi to send correction data to NTRIP

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.
