ATV-mode GPR and EM Surveys

07 November, 2024

Purpose: ATV-mode Ground Penetrating Radar (GPR) and Electromagnetic (EM) surveys are designed for efficient, high-quality data collection over expansive and challenging areas. By using an All-Terrain Vehicle (ATV) as a mobile platform, these surveys increase speed and safety while maintaining the detail needed for subsurface analysis. ATV-mode is particularly advantageous for covering large or difficult terrains that may be hazardous or impractical to survey on foot.

Applications:

Large-scale Data Collection: ATV-mode is well-suited for projects where vast amounts of data are required in a short time. It enables rapid surveying with minimal setup and fewer operators, reducing both time and costs.

Inaccessible Terrain: By traversing difficult or risky ground with an ATV, this mode provides a safe alternative to walking-mode surveys, allowing access to areas that may pose dangers or significant physical obstacles.

Technical Process: In ATV-mode, a 100 MHz GPR system operates alongside a high-powered EM34-3 instrument set at a 20-meter inter-coil spacing. This setup allows the single-operator ATV to collect continuous, high-resolution data over large areas. The higher-powered EM setting ensures deep penetration, while the GPR’s frequency provides detail appropriate for a variety of subsurface features.

Key Uses: Ideal for environmental assessments, mineral exploration, and geotechnical studies, ATV-mode GPR and EM surveys offer a reliable method for obtaining detailed subsurface data across expansive and rugged terrains, increasing operational efficiency and data quality.
