Paul Ssali — Sun, 20 Dec 2020 05:46:13 +0000

http://geotechru.com/oko-3-gpr-with-control-unit-2/

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.
