A notebook (Display is 12-14 inches. The size is not more 340x280x35 mm. The weight is 2-2.5 kg. The power consumption 5060W, power supply – 19V, CPU – not less 1 GHz. RAM – not less 512 MB, HDD – not less 40GB, Software – Windows XP/Vista) is
used for GPR data processing and interpretation in a field and in the office.
The Control unit
The Control unit is designed for control of all GPR operating modes.
The control unit receives commands from the notebook computer by
Ethernet interface, calculates the current parameters for the antenna and
transfers them via RS-485 interface to the antenna, transfers commands
of operating mode to the antenna, receives the data from the antenna,
makes the secondary processing of these data and transfers the
processed data to the notebook via Ethernet interface. The voltage
converter, designed for notebook power supply unit is built into the
control unit An external control keyboard and an automobile odometer
are provided as extra options.
The Control Processing Unit
The Control Processing Unit is designed to control all GPR operation modes,
to display georadiolocaton cross-section in the screen, to record them on a
flash-disk, to execute the initial processing of the obtained data and to
exchange data with the PC via Ethernet interface. Control Processing Unit
operates with the antenna directly, a notebook computer and a control unit are
not required in this case.
The Control Processing Unit was designed especially to operate in unfavorable
conditions and is produced as all weather conditions (temperature -20
…+50° ).
Data is put out onto a colored LCD display indicator with an enhanced contrast
ratio, size 6.5’’, with a resolution 640 480 points. The obtained data are
recorded on the built-in flash-disk with capacity 1 Gb. Power consumption is
no more than 8W.
Radio modem RM-2
The Radio modem is designated for GPR remote control. While working
with it the operator with a notebook may be in a place protected from
external weather conditions, and at the same time another operator moves the
antenna by profile. The radio modem can be used only with the control unit.
This set consists of a radio modem (RM-2), a carry bag and the radio modem
cable. The maximum remoteness in the open area is 100 m. Connection is
accomplished through Wi-Fi.

Odometers
Odometer DP-32
Odometer DP -32 (Figure 4.9.1) is for exact setup of GPR results to the
local area. It is used to move the antenna on a solid surface. Configuration
DP-32 allows using it in unfavorable weather conditions. Power is supplied
, capacity 1,5V. The data is transferred via the optical
with two elements
cable.
Automobile odometer DPA
Automobile odometer is used during operations upon an automobile, it is
connected directly to the vehicle odometer
Odometer Spool:
Spool is used during off-road operation or in small water pools.
The end of the thread is fastened to the idle object in the beginning of the
cross-section. When the antenna is moving, the distance measurement is
performed at the expense of the rolling thread.
Power is supplied by two AA elements, voltage 1,5 V. Data transfer is
performed via the optical cable.

NTENNAS
Set of OKO-2 antennas covers frequencies from 50 MHz for deep geological surveys up to 3000 MHz for highresolution investigations. Using low-frequency antenna one can increase the depth of sounding; however if high
resolution scanning of the near surface section is required one is to use high-frequency antennas. Combination of
antennas with different frequencies yields best results.
