Groundvue 3 - Multi Channel

Like all Groundvue Ground Probing Radars, Groundvue 3 is user friendly and uses easy to operate dedicated software. Operating depth (measured in travel time) and the distance between samples must be defined accurately. All other parameters can be reset after survey.  This is the original 4 channel multi-channel version of Groundvue 3.  It can be used as a single channel or with any number of antennas up to the system maximum of 4 transmitters and 4 receivers.  

Frequencies can be used in any combination.  Because the antennas are simultaneously triggered (without cross channel interference), one transmitter can be used with up to 3 receivers.  This is very useful for automatic velocity calibration.  See Unique GPR Tools.

Frequency Ranges

4GHz (using Groundvue 5 as 1 channel), 1.5GHz, 1GHz, 400MHz, 250MHz

Depth Range

Dependent on Frequencies used –

  • 4GHz: up to 0.5m in dry conditions
  • 1.5GHz: up to 2m in dry conditions
  • 1GHz: up to 2m in dry conditons
  • 400MHz: up to 5m in dry conditions or up to 3m in wet conditions
  • 250MHz: up to 10m in dry conditions or up to 5m in wet conditions.

Special Features

  • Simultaneous multi-channel
  • High Speed Operation (4 channel equivalent of 1000 scans/second)
  • Arrayed Antennas
  • Fully Screened
  • Suitable for towing behind or attachment to a survey vehicle
  • Simultaneous recording of GPS/Total Station data
  • Versatility – the same system can be used in different combinations for a range of tasks (multi channel multi frequency/multi channel same frequency)

Data Storage

Direct to solid disk

Resolution

High to very high (80mm @ 250MHz;
40mm @ 400MHz; 20mm @ 1GHz;
15mm @ 1.5GHz; 1mm @ 4GHz)

Ancillaries

  • Data Logger required for operation and initial data storage
  • A long term data storage system is essential
  • A basic 12V battery charger is needed to charge the radar batteries

Optional

  • Cable connector with vehicle cigarette lighter connection for saving datalogger batteries (not essential)
  • Analytical software – the ReflexW package – is also available. Details on request.
  • Groundvue 3 is also available as a single channel system with the same range of frequencies
