The OKO-3 GPR is a portable lightweight low-prices system designed for non-destructive environmental monitoring. The OKO-3 GPR includes the control unit and antennas. All antennas are interchangeable and meet the needs of a broad range of applications.
The control unit is designed for control of all GPR operating modes. CU are manufactured in two types – one channel (one antenna unit can be connected) and two channel (possible to connect two antenna units)..
The control unit receives notebooks’ orders via Ethernet interface or Wi-Fi channel, processes antenna units’ current set-up and send it via RS-422 interface to antenna unit, sends to antenna commands for operational mode, receives data from the antenna unit, arrange secondary data processing, transfers the data after processing to via Ethernet interface to notebook.
GPR ANTENNAS
Antennas covers frequencies from 50 MHz for deep geological surveying to up to 2500 MHz for high‐resolution investigations. Using low‐frequency antennas, 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 antennas. A combination of antennas with different frequencies yields best results.

SHIELDED ANTENNAS
For efficient work in conditions of existing air jamming (i.e. buildings, construction, power transmission lines, etc.), a set of antennas with shielded screen receivers and transmitters, protecting against the potentially harmful effect from the top semi‐sphere, are available.
DUAL‐FREQUENCY ANTENNAS
The integrated multi‐frequency GPR OKO‐2 is designed for automated location of objects at different depths, simultaneously and in real time. This GPR combines a control unit and two antennas with the different frequencies.
HORN ANTENNAS
Horn antennas are ideal for tasks associated with the high‐speed GPR surveying of elongated objects such as motorways and railways, which require ground lift‐off GPR location.
MULTIPLE LOW FREQUENCY ANTENNA: 15 MHZ, 25 MHZ, 35MHZ, 50MHZ, 100 MHZ
We can customize our low frequency antennas by customer's demand.
High frequency antennas (such as 1600MHz, 2600MHz, 2800MHz, 3000MHz) can be customized by customer's demand.
