Use Ground Penetrating Radar devices and GPS Base Stations manufactured by Earth Science Systems with your Android phone or tablet. For optimal GPS Base Station accuracy, your GPS Base Station must be authorized to receive assistance, and your phone or tablet must have cellular internet service.

With a GPS Base Station this app allows you to:
- Survey surface features of buried utilities in Survey mode.
- Export surveyed points to KML.
- Switch to GPR Assistance mode (for use with a Windows tablet).

With a GPR Utility or GPR Concrete scanner this app allows you to:
- Perform basic GPR scans to detect subsurface objects.
(Additional scan features available using the Windows app.)
- Measure depth of objects by fitting a hyperbola.
- Export scan to PDF or PNG.
- Remotely control the Windows GPR Logging App when used simultaneously.
