2.1.4 Mode View and Mode Switch
a) Mode view
When receiver is powered on, flip the power button and then it will voice
broadcast the current working mode and data link.
b) Mode switch
When the receiver is powered on, connect it with handheld or other
instruments so as to set up and switch the working mode of receiver. See
detailed operation procedures in Cube-a User Manual.
2.1.5 Receiver Self-check
Self-check functionality is to check whether every module works normally.
When S800A receiver has indicators off or module doesn’t work normally,
you can use self-check to inspect the receiver. S800A self-check consists of
four parts, namely GPS, radio, WIFI and Bluetooth. The self-check results will
be voice broadcasted in the process. Self-check operation and result
broadcast are as followed:
a) When receiver is powered on, press power button and hold it until
the receiver voice broadcasts “power off”. Press it again until the receiver
sounds a beep and voice broadcasts “self-check”, which means the receiver
starts to operate self-check. (New receiver is recommended to operate self-
check at least once.)
b) In the process of self-check, each module inspection is followed by
its inspection result. If the module inspection passes, it will voice broadcast
“OK” and module led keeps on until the whole self-check finishes. If the

S800A GNSS Receiver –User Manual 10
module inspection fails, it will voice broadcast current module inspection fail,
keep module led flashing and buzzer sounding until you restart the receiver.
Self-check lasts for about 1 minute. If there is self-check failure, please
contact local dealer.
c) If every module indicator is lit with no flashing, and voice broadcast
says every module work normally (such as “GPS self-check. OK.”), it means all
the modules work normally. Receiver starts to work after the whole self-
check finishes.
2.2 Standard Accessories
2.2.1 Transport container
There are two kinds of S800A containers: Rover container and Base
container. These two containers have similar appearances but their insert

3. Field Surveying
3.1 Static Surveying
3.1.1 Static Surveying Introduction
Static Surveying is an GPS positioning measurement by installing three or
more GNSS receivers at different measuring stations to measure
simultaneously so as to get the relative positions of measuring stations.
Scope of application:
•the establishment of national geodetic control network (second or the
following class)
•the establishment of precise engineering control network, such as
bridges measurement, tunnel measurement
•the establishment of various densified control network, such as city
measurement, mapping control point measurement, road measurement
and boundaries location.
•GPS measurements including control survey used for mapping, cadastral
surveying, land information, real estate surveying, geophysical
prospecting, surveying and building construction in small and medium-
sized cities and towns, which should meet the accuracy demand of D or
E class GPS measurement.

S800A GNSS Receiver –User Manual 15
3.1.2 Static Surveying Operation
a. Set up the tripod at the measuring station, switch the receiver to
static mode and attach it to the tribrach, centering and leveling it in strict
standard.
b. Measure the height of antenna.
c. Record names of station and receiver, height of receiver,
measurement start time, measurement end time, observation session and
satellite number.
d. Static data logging: Power on the receiver and make sure it’s in
static mode. Receiver starts to search satellites and satellite led starts to be
flashing. When it meets the record demand, the satellite led will be flashing
at default sampling interval, and one flash represents having logged an
epoch.
e. Power off the receiver after finishing data logging, and then transmit
the data and do the indoor data processing. (See detailed operation
procedures in Cube-a Software (V3.0) User Manual.)

S800A GNSS Receiver –User Manual 16
3.1.3 Design Principles of GPS Control Network
（1）In order to ensure the continuous tracking observation of satellites and
quality of satellite signal, set up the GPS measuring station in locations which
are free of obstructions, where the altitude angle of obstacles should be less
than 15°in the field of view.
（2）In order to reduce or avoid interruption from electromagnetic wave to
satellite signal, set up the measuring station away from high-power radio
source (such as television station, broadcasting station and microwave
station). And there should be no object nearby that can strongly reflect
satellite signal (such as large-scale buildings).
（3）Measuring station should have convenient transportation and stable
ground foundation, easy for state holding and beneficial for extension of
other measuring method and joint measurement.
3.1.4 Data acquisition method
There are 2 acquisition methods of data: manual start and automatic start.
Open the Cube-a software on the handheld, click “Device” –
“Communication”, choose the receiver model and the communication mode.
There are Bluetooth and WIFI two communication modes.
a. Manual start
Click “Device” - “Working mode”, choose “Static”. At here, you can configure
static parameters, antenna parameters and satellite system.
b. Automatic start
Click “Device” - “Working mode”, choose “Static”. At parameter settings,
choose auto record static data and at the next time when the receiver is

S800A GNSS Receiver –User Manual 17
powered on, it can automatically start static data logging with no need to
reset.
3.2 RTK Dynamic Measurement (Radio)
RTK dynamic measurement (base and rover) has radio mode and network
mode, which two differs from each other in their ways of transmitting
differential signal.
3.2.1 Installation of Base
（1）Set up the tripod in location with known coordinates or unknown
coordinates, level it and attach the receiver on it.
（2）Set up the receiver according to the chosen data link. If using the
internal radio transmission, attach the internal radio antenna into the UHF
antenna port of receiver; if using external radio transmission, connect the
external radio to 5-pin port with 5-pin cable.
（3）Power on the receiver and select base mode.

S800A GNSS Receiver –User Manual 18
3.2.2 Start of Base
Open Cube-a on the handheld to choose communication mode. Click
“Device” - “Working mode” to choose base mode and configure its start up
mode, parameters, data link and satellite system and other settings.
Base has 2 start up modes.
a. Use Current Coordinates
Base uses approximate WGS-84 coordinates of current location as base
coordinates.
b. Input Base Coordinates
User specified base coordinates: the specified base coordinates cannot be far
away from the precise WGS-84 coordinates of the current location, otherwise
the base cannot work.
3.2.3 Installation of Rover
After the installation of base, start to install rovers.
（1）Fix the bracket on the pole, fix the handheld to the bracket and then
install the rover on the pole.
（2）Attach the internal radio antenna or connect the external radio
according to the chosen data link.
（3）Power on the receiver and select rover mode.

S800A GNSS Receiver –User Manual 19
3.2.4 Configuration of Rover
Open Cube-a software on the handheld to choose communication mode.
Click “Device” - “Working mode” to choose rover mode and configure its
data link, antenna parameters and satellite system and other settings. When
data link is internal radio, you need to configure the radio channel,
frequency, protocol and power.
Note:
1. If you want an high-precision surveying result (several cm), it’s
recommended to use a tripod to install rover;
2. When the coverage of surveying area is large (over 4 km from base),
the working distance too far for internal radio to meet the demand, it’s
recommended to use external radio to connect the receiver;
3. Under radio mode, frequency and protocol settings of base and
rover should be the same.
