K70-GNSS Handheld Terminals-Kilichain

Overview

A new generation of high-precision industrial-grade GNSS handheld device, supporting centimeter-level accuracy and a 5.5-inch ultra-clear large screen. Built-in high-precision board, combined with an external four-arm spiral antenna, supports all global civil navigation satellite systems (including BDS, GPS, GLONASS, Galileo, IRNSS, QZSS and SBAS). Supports RTCM protocol, supports multi-system multi-frequency raw observation data output, and can be widely used in third-party integration and application. Integrated with RTK technology, centimeter-level navigation accuracy can be achieved by receiving base station correction data. Applied to various spatial data collection, inspection and patrol work, widely used in land, electricity, forestry, environmental protection, highway, railway, ship monitoring, oil and gas pipelines, mining boundary exploration and other industry applications.

Key Features

Real Time Kinematic Support

Support BDS, GPS, GALILEQ. GLONASS, QZSS full-system GNSS, built-in RTK algorithm, supports centimeter-level accuracy.

Four-arm Helical Antenna

The four-arm helical antenna has a cardioid pattern, a good front-to-back ratio, and excellent wide beam circular polarization characteristics, making it very suitable for use as a receiving antenna for satellite positioning systems. The tablet is equipped with an antenna that gives this advantage.

Waterproof and Dustproof

The IP65 protection level enables the tablet to maintain normal operation in a variety of environments and stably collect workplace data.

Long Battery Life

Although the device is small, it still has a long battery life. Moreover, the battery is removable, and the battery replacement is feasible and efficient, ensuring the uninterrupted execution of project data collection.
