Chapter1 Introduction

§1.1 K300 GPS System Summary

K300 combines the advantages of Horizon RTK products, follows

advanced technology and the concept of continuous innovation,

bring the most advanced surveying solution to surveyors, offers

higher accuracy and more reliability, makes surveying work easier

and simpler.

This manual takes K300 measuring system for example to explain

how to install, set up and use the RTK system as well as the use of

the accessories. We recommend that you read these instructions

carefully before using the instrument.

§1.2 Features

Horizon RTOS platformHigh Frequency CPU

Horizon RTOS is a new embedded real-time operating system with

high efficiency and low powerwhich is professionally applied on

GNSS RTK products; it has strong and rapid ability to process

instructions, start with lightning. Main frequency of CPU reaches up

to 200 m, can handle complex satellite encoded data rapidly in real

time, reliable and steady.

The transceiver integrated built-in radio, base station and rover

- 2 -

station completely interchangeable

K300 has a built-in transceiver integrated built-in radio, the

transmitted power of which is 0.5W2Wand it makes switching

between base station and rover station freely.

Double high capacity battery

Dual battery pack design, consist of two 4400mAh battery, total

capacity is 8800mAh; needn’t to disassemble, and charge the

mainframe directly.

Full color OLED display, more suitable for field work

K300 adopts LCD screen, which is one of the most popular function

of this model. K300 uses 1.54 inch OLED color screen, with high

brightness and low power, and more suit to field work.

The new network architecture, with fast and stable data link

Standard UHF data transceiver integrated module and GPRS

communication service module (optional 3G module) seamless

compatibility with CORS system.

Performance of high-strength engineering

Professional PBT+PC industrial shell and high-quality materials,

green rubber waterproof ring, unique industrial design, IP67 class
