Introduction
Congratulations! You have just acquired the latest dual-frequency A30 GNSS Surveying
System from FOIF! GNSS has revolutionized control surveys, topographic data collection
and construction surveying. Purchasing the right tools for a professional job is essential in
today's competitive business environment. Learning to put these tools to work quickly and
efficiently will be the focus of the present manual. Compared with other GNSS products,
A30 is more compact and lightweight while integrating more technology, such as the
exclusive multi-constellation (GPS+GLONASS+SBAS) capabilities.
A30 performs a more advanced features than A20 such as designing and operating. You will
find many modifications in this instrument different from the generation A20. A30 keeps
the same RTK accuracy as A20, still it gives you the accuracy with horizontal 1cm+1ppm
and vertical 2cm+1ppm. Super bright OLED and voice message give you more convenience
through working time. Internal memory is enlarged from 256MB to 4GB which should be
enough for your whole project. There has a built-in sensor inside the instrument to help you

Safety Information
This manual describes the A30 GNSS Receiver.
Before you use your receiver make sure that you have read and understood this manual, as
well as all safety requirements.
WARNING
CAUTION
Ignoring this indication and making an operation error could
possibly result in death or serious injury to the operator.
Ignoring this indication and making an operation error could
possibly result in personal injury or property damage.
Regulations and safety
The receivers contain integra Bluetooth wireless technology, and may also send radio
signal through the antenna of an internal radio-modern, or through an externally-connected
data communication radio. Regulations regarding the use of the 460MHz radio-modems
vary greatly from country to country. In some countries, the unit can be used without
obtaining an end-user license. Other countries require end-user licensing. For licensing
information, consult your local FOIF dealer. Bluetooth operates in license-free bands.
Exposure to radio frequency radiation
For radio (410~430MHz/430~450MHz/450~470MHz)(RX Only)
It is safety. Exposure to RF energy is an important safety consideration. Proper use of this
radio modem results in exposure below government limits.
The following precautions are recommended:
lDO NOT operate the transmitter when someone is within 20cm of the antenna.
lDO NOT collocate (place within 20cm) the radio antenna with any other transmitting
antenna.
lDO NOT operate the transmitter unless all RF connectors are secure and any open
connectors are properly terminated.
lDO NOT operate the equipment near electrical blasting caps or in an explosive atmosphere.
lAll equipment must be properly grounded according to FOIF installation instructions for
safe operation.
lAll equipment should be serviced only by a qualified technician.
For wcdma radio
- For your own safety, always observe the precautions listed here.
- Always maintain a minimum separation distance of 20cm between
CAUTION
yourself and the radiating antenna on the radio-modem.
- Do not collocate (place within 20cm) the radio antenna with any
other transmitting antenna.
For Bluetooth radio
The radiated output power of the internal Bluetooth wireless radio is far below radio frequency exposure limits. Nevertheless, the wireless radio shall be used in such a manner
that the FOIF receiver is 20cm or further from the human body. The internal wireless radio
operates within guidelines found in radio frequency safety standards and recommendations,
which reflect the consensus of the scientific community. FOIF therefore believes the internal
wireless radio is safe for use by consumers. The level of energy emitted is far less than the
electromagnetic energy emitted by wireless devices such as mobile phones. However, the
use of wireless radios may be restricted in some situations or environments, such as on
aircraft. If you are unsure of restrictions, you are encouraged to ask for authorization before
turning on the wireless radio.
Installing antennas
- For your own safety, always observe the precautions listed here.
- Always maintain a minimum separation distance of 20cm between
CAUTION
yourself and the radiating antenna.
- Do not collocate (place within 20cm) the radio antenna with any
other transmitting antenna.
This device has been designed to operate with the antennas listed below.
UHF Antennas not included in this list, or that have a gain greater than 5dBi, are strictly
prohibited for use with this device. The required antenna impedance is 50 ohms.
The antennas that can be used (country dependent) with the 460 MHz radio are 0dBi and
5dBi whip antennas(only for UHF, RX only).
The antenna that can be used with the wcdma radio is the 5dBi whip antenna.
To reduce potential radio interference to other users, the antenna type and its gain should
be so chosen that the equivalent isotropic ally radiated power is not more than that permitted
for successful communication.
Rechargeable Lithium-ion batteries
These receivers use a rechargeable Lithium-ion battery.

Summar y
A30 is regarded as an highly integrated, semi-open structure and modular designed RTK
system independently researched by FOIF. GNSS antenna,data link, WCDMA,Li-Ion
battery, memory device, bluetooth etc. are all focused in one receiver. Moreover, GNSS
antenna, datalink and battery are independently modules which are easy to replace thus
which is convenient in the products maintainance and upgrade. Stable industry standard
handheld for A30 has inner or external GPS antenna and camera for optional function to
upgrade this handheld to a GIS collector. 3G memory device is also optional for the handheld, thus can further upgrade to a highly accurate GIS collector. Meanwhile, besides the
two data transmission ways (WCDMA, data Link),we can use 3G function of the
mobile phone to do the RTK job, in this way, we can say A30 has already existed in 3G
period.
With high accuracy, fast tracking function of inner GNSS mainboard,A30 can track the
satellite signal as more as 220 channels simultaneously.
Highly sealed, waterproof, dustproof, shockproof, low power consumption are its basic
inspecting rules. With super and weatherable OLED screen built on A30 receiver, the real
time information of the receiver can be shown on the screen. 4 lights and 4 buttons are
easily used to set the receiver, and the voice aided is helpful to the outdoors surveying.
Downloading and backups of the static data could be convenient because of the inner SD
slot, thus resolves your trouble for the insuffcient memory.

Static Sur veying
A30 also has static surveying function, which includes outdoors surveying and office
working.
6.1
Process
1) Fix A30 on tripod.
2) Measure the height of A30.
3) Turn on A30 while more than 4 satellites are tracked by this instrument, then start the
static surveying from the buttons of A30 screen.
4) It is important to record the surveying time, SN of A30,height of A30, etc. on a notebook
while this receiver is doing the static surveying.
5) When outdoors surveying is over, turn off A30.
Notice:
Normally, it is better to record the static data on SD card.
6.2
Data Downloading and Format Converting
1) Connecting A30 and PC for data downloading.
2) File name given should according to the notes of outdoors surveying made by yourself.
SN of A30, surveying time and point name should all be indicated in the file name for
your easy distinction. For example, A30, the detailed information is,A300000086(SN

of receiver) for the first time surveying at 9am to 10am on CPI0023(point name), so we
can give its name as 0023086A. Further more, still this receiver for the second time
surveying at 11am to 12am on CPI0027. So then we can give its name as 0027086B which
is different from 0023086A,although we use the same receiver to do the job.(The front 4
numbers are point name, the later numbers are SN of receiver, the last capital letter is
surveying time.)
3) Convert these data to RINEX format and input the height of A30. You can finish this by
the software FOIFGNSS shown below.
4) Click
Import raw files for translated to RINEX
, choose the files that need to be
converted.(These files are downloaded from receivers.) This software can convert as
much as 16 files at the same time.
5) Choose the files that you want to convert, then click

Ways of Outdoors Working for Static Surveying
1) Surveyors should give a general understanding about their surveying district e.g. point
position, difficulties of making point and also includes the economic level, culture
custom, traffic situation etc. at that place.
2) Ephemeris forecast: Good surveying opportunities should depend on the surveying
position and the latest satellite ephemeris. The satellite ephemeris includes many aspects
e.g. visibility of satellites, satellite constellation, PDOP etc. If big building is beside the
point, then you should give a conclude on whether this big object would influence the
effects of static surveyings on that point.
3) Give a detailed surveying precedure on the paper.
4) Outdoors surveying: Comply with the surveying procedure and related receiver manual
to lead your job.
5) Data transferring: Check the consistency between outdoors notes making and the files in
the receiver by PC.
6) Process baselines to determine the accuracy of your surveying thus leading your next
working plan.
7) Finish working if there has no problem in step 6) and then print your adjusted results
report.

Notice:
To achieve a better accuracy and reliability of the project, it is asked that you should have a
knowledge of the ephemeris and the status of ionosphere to avoid the troubles from
surveying.

GPS Network
Network Designing
1) The baselines should be closed. Single baseline is not accepted in the designing.
2) It is not right to say that the more the baselines, the better the results are. Three baselines
for one point is suitable for the reliability of network.
3) For getting the higher accuracy of the point, one point for two times surveying is suggested.
4) In order to convert GPS system to your local coordinate system, you should have at least
3 to 5 higher accuracy known point that are equally spread in the survey district for your
good coordinate converting. At the same time, if you want to get your good elevation of
the surveying points, then you should have certain leveling points for your research on
the elevation of your surveying district.
5) Considering the convenience of static surveying, it is suggested for you to give your
points in the wild place where you are easy-going.

Accuracy Standard in Static Surveying
Accuracy standard in static surveying is judged by the rms of distance in the adjacent
two points.
a 2 + (b * d ) 2
a : fixed error (mm)
: rms (mm)
b : scale factor (ppm)
d : distance (km)
The surveying accuracy for GPS is divided into 6 levels by Surveying Standard for GPS
published in 2001 (AA, A, B, C, D, E). AA, A, B are for country s GPS control surveying.
Level C is mainly in engineering surveying of big or middle cities. D and E are for control
surveying in middle or small cities

GPS Network

There are many kinds of GPS network designing such as tracking, alternately observation,
multi-base, single-base, normal.
Tracking: Several receivers fixing at the certain points for a long time observation (such
as 1 year without stop), which is suitable for level AA control survey or permanent monitoring survey.
Alternately observation: Several receivers fixing at the points of certain district, they also
need long time surveying (several days), after this procedure, change the receivers
to the other points of this district, then use the same surveying way. This mean can
eliminate the influence of SA. It is suitable for the GPS network survey of level A
and B survey.
Multi-base: While several receivers are fixing at the base points (like CORS) with long time
surveying, then we can use other rovers working in this net simultaneously. It is
suitable for level C and D survey.
Single-base: Use one receiver fixing at the base point working continuously, then use rovers
to do the surveying job around base point. These rovers do not need synchron.
As a rover fix at one point, one baseline is formed. Several rovers then can form
many baselines which have the same base point like a star. It is suitable for level
D and E survey.
Normal: This way is just the general way for customers. You just follow the manual and do not
48
A30 User Manual
need to have many professional knowledge. Detailed way is, using 3 or more receivers
fixing on points to do the static surveying for a certain while (usually 40-60 minutes)
simultaneously. This moment, one polygon is formed by these receivers. After the first
surveying time is over, move these receivers to other points doing the same surveying job
(another polygon is formed by the second time surveying) but make sure that the two
polygons should have common side. The whole GPS network is formed by these polygons.
It is suitable for level C and D survey.
6.4.4
Shapes of GPS Network
Depend on different applications, shapes of GPS network can be divided into several types:
Radial network, Point connecting network, Side connecting network, Polygon connecting
network and Mixed connecting network.
Radial network is a simple geomatic figure, but it is not
easy to check the accuracy because all the sides of that
network are not closed. The advantages for this type is:
only need 2 receivers, which is regarded as an easy-working,
fast-tracking way. It is widely used in low precision
Radial network
engineering surveying, cadastra survey, mapping and so on.
A30 User Manual
49
Point connecting network is defined as a figure by connecting two adjacent shapes by only one common point. The
advantages for this type is high efficiency, fast extending,
but it also can not confirm the high precision surveying. So
it is not suggested in precise working.
On the left is 3 receivers working simultaneously in the
Point connecting network.
Point connecting network
Side connecting network is defined as a figure by connect
ing two adjacent shapes by their common side. It is as same
as normal GPS network designing shown in the last paragraph and is widely used in the surveying field because of
its high precision.
Side connecting network
A30 User Manual
50
Polygon connecting network is defined as a figure connecting the two adjacent shapes by at least 3 common points.
So this network at least needs 4 receivers. It is better than side
connecting network in accu racy but not working time. So it is
only suggested for high precision control surveying.
Polygon connecting network
Mixed connecting network
Because every type of network has its own disadvantage, so we can use Mixed connecting
network which can combine the advantages of these types to achieve higher efficiency
working but lower investment both in time and money.
Mixed connecting network is also the common type in doing the surveying job.
6.4.5
Principles of GPS Network Designing
Principles for GPS network designing include 3 parts, point position, reliability and
accuracy.
A30 User Manual
51
Point position
1)Widely place is suggested because of good satellites signals, big buildings are not
allowed at the range of 10 ~ 15 in elevation mask.
2)Keep 200m away from high power WiFi object, e.g. radio, powerline etc.
3)It is better to be removed from the large water area, high building etc. to avoid or reduce
the effects of multipath.
4)The place for point position should be easy-going and also steady for further applications.
Reliability
1)Longer surveying time.
2)Repeated station setting is suggested.
3)Comfirm that one point should be involved at least 3 baselines.
4)The sides for every part of the network should not exceed 6.
Precision
1)Synchronous surveying is suggested in the adjacent points.
2)GPS network designing is suggested.
3)The sides for every part of network should not exceed 6.
4)High precision EDM instrument is recommended to use together with GPS receivers.
5)Leveling points should be equally spread in the district for better elevation fitting.
6)Surveying time (times) could be added appropriately for higher precision surveying.
7)Known points should be equally spread in the district for better precision surveying.
