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 georadiolocation cross-section in the screen, to record them on a flash-disk, to execute the initial processing of the obtained data and to exchange dara 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 °C). Data is put out onto a colored LCD display indicator with an enhanced contrast ratio, size 6.5", with a resolution 640x480 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.

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.
