2 Setting up the receiver
This chapter provides general information on environmental requirements, setup, power
supply and connection of the M6.
2.1 Environmental requirements
To keep the receiver with a reliable performance, it is better to use the receiver in safe
environmental conditions:
Operating temperature: -40°C to +65°C(-40 °F to 149 °F)
Storage temperature: -40°C to +85°C(-40 °F to 185 °F)
Out of corrosive fluids and gases
With a clear view of sky
2.2 Front panel
Receiver front panel contains 2 indicator LEDs, Power button. The indicator LEDs show
the status of differential, satellite tracking and battery power.For detailed information, see
chapter 3.2.
2.3 Lower housing
Receiver lower housing contains, UHF radio antenna connector and a threaded insert.
2.4 Power supply
M6 supports internal batteries and external power input.
2.4.1 Internal batteries
The receiver is equipped with Lithium-ion batteries, which can not be disassembled at
will. The M6 adopts the internal battery design that provides you an effective survey
workflow. The internal batteries typically provide about 20-hour operating time as a rover.
However, this operating time varies based on environmental conditions.

Battery Safety
Charge and use the battery only in strict accordance with the instructions below:
Do not use or charge the battery if it appears to be damaged. Signs of damage
include, but are not limited to, discoloration, warping, and leaking battery fluid.
Do not expose the battery to fire, high temperature, or direct sunlight.
Do not immerse the battery in water.
Do not use or store the battery inside a vehicle during hot weather.
Do not drop or puncture the battery.
Do not open the battery or short-circuit its contacts.
Charging the Lithium-ion Battery
Please charge the internal battery via type-c cable
Storage of the Lithium-ion Battery
Keep batteries in dry conditions.
Dispose of the Lithium-ion Battery
Discharge a Lithium-ion battery before dispose of it.
Dispose of batteries is an environmentally sensitive manner, and adhere to any local
and national regulations concerning battery disposing or recycling.
WARNING – Do not damage the rechargeable Lithium-ion battery. A damaged battery
can cause an explosion or fire, and can result in personal injury and/or property damage.
2.4.2 External Power Supply
The receiver is connected to an external power supply through a Type-C cable, and make
sure that use an external power supply with the correct voltage of M6, such as a 6-9V
power pack. Over-voltage function cannot protect your M6 if reverse connection.
Tip: The power consumption will be increasing if the base station transmits correction data through internal
UHF in the RTK mode; therefore, we strongly suggest using external power (6-28 volt DC) for the base
station.
2.4.3 Charge Battery via M6
The battery of the receiver cannot be disassembled at will. However, the Type-c interface
makes its charging mode more flexible. M6 supports adaptive charger for fast charging
protocol. The standard voltage is 9V. The portable mobile power supply can charge and
power it anytime and anywhere.
1．Power off M6 receiver and enter charging mode;
2
．
Connect M6 receiver to Adaptive charger with type-c cable;
3
．
The LED light on the front panel of the receiver will flash according to the
battery percentage, and the green light will be on when it is fully charged.

4 Static survey
Static survey is commonly applied for control points, which requires millimeter accuracy.
After connecting with Bluetooth, you can record static data to your controller or receiver
directly.
The static data in controller
For record static data in controller, you can configure it and change sampling interval via
GNSS Suvery. It’s sample frequency supports 0.1s, 0.2s, 0.5s, 1s, 2s, 5s, 10s, 15s, 30s,
60s.
You can enter File name, Station name, Antenna
height, Sampling -> Click Start record, the
recorded raw data will be saved in the
corresponding path.
The raw data is in .cnb format, you can transfer
to RINXE format through CRU software.
The static data in receiver
You can record static data to receiver memory by Mfield Survey software, this function is
available for M6 GNSS receiver.
M6
GNSS Receiver User Guide
12
Station name: The static will be stored in this folder,
Record space: Default is 600 MB, this is set record space for the current static file.
Antenna: Set the antenna height and measure type, it will be recorded in the static file.
Sample interval: Choose sample frequency, supports 0.05s, 0.1s, 0.2s, 0.5s, 1s, 2s, 5s,
15s, 30s, 60s.
File split: Choose file split, support every 5\10\15\20\30 minutes or 1\2\4\24 hours to
save a file and file split manually, default is manual. If you select 24 as file split, it
will create two data file when it occurs to 24 o'clock (UTC Time). One is from start
time to 24 o’clock, another is from 0 o’clock to end time.
Data format: Support CNB\ Rinex3.02\Rinex2.10
Loop: When storage is full, Yes means delete earliest data and store continually, No
means stop recording
Mode: Support manually and automatically recording mode.
Click to change the data range
In File interface, you can check the static files by day/week/month. You will find the
folder, and the static data is in the specific folder. Long press the static data, choose to
delete the file.
4.1 Static Data Collection
Static survey is mainly used for the control survey. To reach millimeter accuracy, follow
as below:
At least 3 GNSS receivers are required to form a stable triangulation network.
It is better to set Data Log Session as manual on the known point.
Power off the receiver before moving to other observation site.
To quickly post-process static observation raw data, write down the station name,
receiver SN, antenna height, start and end time for each observation site.
4.2 Static Data Download
M6
GNSS Receiver User Guide
13
The raw observation data is saved in internal memory of M6 receiver, when connect with
PC via Type-C cable, the M6 receiver can work as a USB Flash Disk, which means you
can copy or cut static data to PC directly.
Tip1: Default memory for M6 receiver is 8GB.
Tip2: The receiver will stop recording raw data if the internal memory runs out.
4.3 RINEX Convert
After copy raw observation data to PC, you can convert the data from MaxNav binary
format (*.cnb) to RINEX in CRU software.
1．Start CRU software;
2．Click Folders and select the path of your CNB data;
3．Click Rinex Convert to check all raw data on main window. Right click on
the file to modify antenna, Convert Settings and Convert to RENIX, or use fast
icon in standard bar.

Click to select the Antenna Type and Measurement. If you cannot find M6
antenna, 1) input the value of R0 (horizontal offset from measurement mark to phase
center), h0 (vertical offset from measurement mark to phase center) and h1 (vertical
offset from measurement mark to receiver bottom). R0 is 0.0650m, h0 is 0.0298m
and h1 is 0.0481m respectively for M6; 2) or check Enable antenna configure file
to select Antennas.ini file to select Antenna type again. You can also add, edit and
delete antenna types based on your requirement.
Click to change Convert Settings, mainly export format and export observation
information.
Tip: In some Post Processing software, the BeiDou observations cannot be processed, you can
uncheck the BeiDou B1,B2,B3 observations.

6.1.2 Tilt survey
Tilt survey option will appear when receiver supports for tilt survey, it is available for S6
Plus GNSS Receiver, use IMU sensor.
According to the IMU sensor, can meets the requirement of high precision measurement.
When the tilts within 60°, the built-in sensor based IMU precisely calculates the actual
offset, which accuracy can up to 2.5 cm.
1
．
Open IMU: Go into Topo survey—click the button to open.
2．Initialization
If you power off the receiver or freset it, need to initialize again. After open IMU button,
you can follow the guidance in interface to complete it. During operation, make receiver
can search the satellites and get a fixed solution.
In survey interface, you can find the bubble and angle value shows the pole you tilt.
For more accuracy, angle less than 60° will be better.
Tip: Do not shake or rotate the receiver violently, otherwise you need to re-initialize.
6.2 Auto survey/Area survey
For Auto survey, it supports automatic and continuous survey according to Time
or Distance.
