Brief Introduction

MG970 is a multi-frequency and multi-satellite RTK survey system called the
pinnacle device of integrated RTK. It has higher integrated body, and makes a
breakthrough to solve the various problems in the RTK device design and
manufacture. MG970 also has stunning accuracy, stability resistance, strong
compatibility and environmental adaptability, the entire device is more portable,
user-friendly and reliable.

Each mainframe of MG970 built a four-feed GNSS antenna with zero phase center,
with P307 multi-frequency and multi-satellite board, full-band UHF radio transceiver,
GPRS \ CDMA network communication module, Bluetooth wireless transmission
module and Micro SD memory expansion module. Using industry-leading ARM
Cortex- M3 32-bit processor designed for the mainframe control system, and it
provides receiver outstanding computational performance and exceptional system
response to events.MG970 combined with multifunction buttons and a high-resolution
OLED screen, it can complete intelligent operation of the mainframe, can be viewed
the state of the receiver chain and data, can be set on the receiver, select receiver
mode, data link mode, the liberation of the hand book, and improve work efficiency

Ⅰ MG970 mainframe

In this chapter, it will show the detailed information of MG970, such as appearance,
interfaces and some basic operation.

The mainframe of MG970 is a flat cylindrical, 100mm in height, 191mm in diameter.
The front side is a LED screen, 2 functional buttons and 3 indicators. The back side is
a battery compartment.

The bottom of the receiver is some interfaces. They include a radio antenna interface,
a GPRS antenna interface, a 5 pin external power interface and a 7 pin RS232/USB
interface.

Ⅱ Basic operation of MG970

In this section, we highlight the basic operation of MG970. It includes powering
on/off, checking work station, changing work mode, self-checking. All of these
basic operations are simple and easy. But they are very important

2.1 Power on/off

This is the first step to use MG970, it’s very easy to operate. Below we will explain in
detail how to power on/off the mainframe.

2.1.1 Power on

When the receiver has battery, keep press power key for some seconds.

Fig 2-1 Power on page

About 5 seconds later, the buzzer will call three times, then the initialization is
completed and you will enter into the main page.

Fig 2-2 work mode: rover, base, static

2.1.2 Power off

Keep press power key in the state of powering on until enter into another menu. It
shows as follow:

2.2.2Switch woke mode

When we get a receiver, we should switch work mode first, it includes base, rover,
and static. Keep press power key in the state of powering on until enter into setting

menu. Then press the function key to switch to “mode”, and you can press the power

key to enter into the mode selection menu. Select the one you want to use, then press
power key to confirm.
