Summary
Introduction
A8 GNSS RTK system adopts modularized design, so as
to enable users to change into different differential
transmission modules according to various requirements.
Those are traditional radio transmission, GPRS and 3G
communication functions. Meanwhile the designed self-
diagnosis function can autom atically check the working status
of all hardware and software of the A8 receiver while working,
and arouse the problem part by its intelligent voice messenger
in case of some problem .
Data collection controller can be connected with receiver
mainframe via Bluetooth or cable; built-in high-capacity
battery is suitable for long-time field work; static data can be
stored in the built-in memory card of receiver and downloaded
via USB port to your PC.
Tips: 1. A8 GNSS RTK system has many modules.
This manual does not represent standard
configuration. Users need to notify their
own requirements for the different
configuration due to different appplications.
2. And before using, we suggest users firstly
to check whether the package box is
damaged, and then open careful and check
whether inner items matched with the
order list of their own. If there are some
missing or damaging cases exist for
products and accessories, please contact
with the local

distributor or Hi-Target Foreign Trade Dep.
Immediately.
3. Last but not least, please carefully read
manual before carrying, handling and using!
Product Features
1. BD970 mother board of Pacific Crest, a Trimble Company,
multi-satellite, multi-system kernel.
2. 1+X multi-module communication units.
3. PCC Radio module (optional) compatible with
Trimble/Leica RTK.
4. Double battery capacity as 4400mAh, 12 hours for RTK
operating.
5. The highest performance in waterproof, dustproof and
anti-drop.
6. Adjustable to be single GNSS system or multi-GNSS
system: GPS, GLONASS, GALILEO.
Usage and Notes
Although A8 receiver using chemical and impact resistance
material, but necessary taking care and maintenance is still
required for such a precise instrument.

Summary
Warning: The receiver must be used and stored
in the specified temperature. More
details please refer to Chapter 7:
Technical Parameters.
To ensure the quality of continuous tracking satellites
and signals, surveying work should be in open air, while there
should no any obstacle in space above 15°altitude angle; in
order to reduce all kinds of electrical interference to the
GNSS satellite signals. Besides, there should not be strong
electrical interference around within about 200m range, such
as the television tower, microwave stations, high voltage
transmission line. Also, in order to avoid or reduce the
occurrence of multi-path effect, stations should be away from
terrain or geographical objects, which will strong effect
electrical signal, such as high-rise buildings, big pool, etc.
Changes or modifications not expressly approved by the party
responsible for compliance could void the user?ÿs authority to
operate the equipment.
This equipment has been tested and found to comply with the limits
for a Class B digital device, pursuant to Part 15 of the FCC Rules.
These limits are designed to provide reasonable protection against
harmful interference in a residential installation. This equipment
generates, uses and can radiate radio frequency energy and, if not
installed and used in accordance with the instructions, may cause
harmful interference to radio communications. However, there is no
guarantee that interference will not occur in a particular installation.
If this equipment does cause harmful interference to radio or
television reception, which can be determined by turning the
equipment off and on, the user is encouraged to try to correct the
interference by one or more of the following measures:
--Reorient or relocate the receiving antenna.
--Increase the separation between the equipment and receiver.
--Connect the equipment into an outlet on a circuit different from
that to which the receiver is connected.
--Consult the dealer or an experienced radio/TV technician for help.
The device must be operated to provide a separation distance of
at least 20cm from User.
