Handheld RTK GNSS Receiver For GEO-Survey

Overview

This is a handheld RTK positioning terminal with built-in 4G and CORS services, using high-precision RTK module, supporting GPS, Beidou, Galileo, QZSS and other satellite navigation system signal reception, RTK fixed solution status Bit accuracy can reach 1-2 cm, suitable for accurate measurement occasions. The 660RTK also has sensors such as a barometric thermometer, a three-axis electronic compass and a three-axis accelerometer.

The 660RTK is optimized for industry applications, with features such as finding points, sharing AB points, topographic survey, grid tree planting, dot measuring area, surround area, straight curve length, etc.

Key Features

• Find out water pile

Identify the water piles and collect the location of each pile before harvesting or plowing, then find the correct location to install the pile before planting.

• Sharing AB point

Share the AB point, and share the collected AB point data with the tractor navigator to avoid the tractor running on the ground for nothing.

• Land survey

Plot measurement, enclosing area, dot area, perimeter, curve length, straight line length.

• Topographic survey

Topographic survey, minimum height, maximum height, average height, the amount of earthwork to make the plane, etc.
