What is GPR (Ground Penetrating Radar)
Ground Penetrating Radar (GPR) is a remote sensing technology that uses radar pulses to detect and map objects beneath the surface without excavation.
How Does Drone-Based GPR Work?
Drones equipped with lightweight GPR sensors fly precise grid patterns, sending high-frequency radar pulses into the ground and capturing reflections from subsurface features. Advanced processing then converts this data into detailed 3D images, revealing buried infrastructure, archaeological remains, or potential UXO hazards using ground penetrating radar
Advantages of Using Drones for GPR Surveys
Access to Difficult Terrain: Drones can cover uneven, hazardous, or remote areas that are challenging for ground crews.
Safety: Minimises personnel exposure to dangerous sites like contaminated land or UXO zones.
Speed: Drones cover larger areas faster than traditional handheld or vehicle-mounted GPR.
High Resolution: Modern drone GPR

Typical Applications of Drone-Based GPR
Typical applications of drone-based GPR include mapping buried utilities and infrastructure, identifying archaeological features without excavation, and detecting potential hazards such as unexploded ordnance (UXO). It is also widely used for assessing ground conditions before construction, investigating sinkholes or voids, and supporting
Typical applications of drone-based GPR include mapping buried utilities and infrastructure, identifying archaeological features without excavation, and detecting potential hazards such as unexploded ordnance (UXO). It is also widely used for assessing ground conditions before construction, investigating sinkholes or voids, and supporting environmental and geological studies. By providing fast, accurate, and non-invasive subsurface data, drone-based GPR helps reduce risk, improve planning, and support safer, more efficient project delivery
