Introduction

This chapter includes overview, receiver features, and devices in the package.

1.1 Overview

TS21 GNSS receiver is an innovative integration of visual positioning technology, GNSS, IMU and dual cameras. Its front camera enables high-precision, high-efficiency and multi-point measurement, allowing you to measure what you see and generate point clouds on site. Its front and bottom cameras work in tandem to support CAD AR visual stakeout, enabling precise path planning at varying distances. Its built-in IMU ensures accuracy without any limitation on tilt angles.

With an internal high-performance multi-constellation and multi-frequency GNSS board, the TS21 GNSS receiver can provide high accuracy and stable signal detection. The high-performance antenna can speed up the time to first fix (TTFF) and improve anti-jamming performance. The built-in large capacity battery supports up to 9 hours of field work in 4G/3G/2G network and Rover radio mode. The built-in UHF radio module supports long distance communication. The rugged housing protects the equipment from harsh environments.
