The OKO-3 GPR is a portable lightweight low-cost system designed for non-destructive environmental monitoring. The OKO-3 GPR includes a control processing unit and antennae. All antennae are interchangeable and meet the needs of a broad range of applications.
FEATURES
•High-speed control unit
•High accuracy of GPR data
•Number of Samples per Scan – 256,512, 1024, 2048, 4096, 8192, 16384
•Compatible with all OKO-3 antennae
•Rugged weather resistant housing
OKO-2 GPR with a control processing unit includes:
•Control processing unit
•Power supply unit BP 9/12
•Charger ZU-9
•Handle-rod (carrying handle or telescopic handle rod – depends on the antenna unit)
•Software GeoScan32
The Control processing unit OKO-3 is a lightweight portable two-channel microprocessor control unit, designed for managing all of ground penetrating radar operating modes. It displays all GPR profiles, saving them on a Flash-disc, processes GPR survey results and exchanges data with a personal computer via USB interface. The control unit can be connected to one or two antenna units.

The CPU OKO-3 is specially designed for operation in adverse weather conditions and can be used in any climatic conditions (performance is guaranteed in the temperatures ranging from -20°С to +50°С).
FEATURES OF THE CONTROL PROCESSING UNIT OKO-3:
•The CPU OKO-3 is specially designed for operation in adverse weather conditions and can be used in any climatic conditions (performance is guaranteed in the temperatures ranging from -20°С to +50°С).
•Data is displayed on an LCD with 10,4’’ window width and 1024×768 resolution. The screen allows one to view data in real time or in playback mode. It is readable in bright sunlight, although an optional sunshade is available for the unit. Prolonged exposure to direct sunlight will cause the screen to heat up and may affect screen visibility.
•The CPU OKO-3 operation has been simplified for maximum efficiency. The touch screen makes it easy to select parameters and modes, while power on and cursor are successfully controlled using spill-resistant buttons located on the front bar.
•The obtained data is stored on the built-in 60 GB SSD.
•The CPU OKO-3 can be charged from a 10.8 V Lithium-Ion rechargeable battery with a 12 A/h capacity, mounted into the housing. Power input is not more than 4 W. Survey time with fully charged batteries is not less than 8 hours. Batteries are charged with an available charger.
•It takes approximately 4-5 hours to recharge the battery. (Be sure to keep the battery slot cover on the unit while it is used to ensure that no dust or dirt enters the unit’s interior.)
GPR OKO-3 Antenna Units
The antennae cover frequencies from 25 MHz for deep geological surveying to 2500 MHz for high‐resolution investigations. Using low‐frequency antennae, one can increase the depth of sounding.If high resolution scanning of the near surface section is required, though, it is advisable to use high‐frequency antennae. A combination of antennae with different frequencies brings best results.

MULTIPLE LOW FREQUENCY ANTENNA: 15 MHz, 25 MHz, 35MHz, 50MHz, 100 MHz
We can customise our low frequency antennae according to customer’s demand.
High frequency antennae (e.g. 1600MHz, 2600MHz, 2800MHz, 3000MHz) can be customised according to customer’s requirements.
All of these antennae are interchangeable, compatible with the control unit or control processing unit, with a variety of different applications.
The CPU of GPR OKO-3 is compatible with all OKO-3 antennae.
