Shallow Detailed & Deep Geological Applications

Monituring sensor network iNOVA SYSTEM

In most cases, GPR surveys are a hard work and can be very dangerous for field personnel due to harsh topographic environments and weather conditions.‎

This is where drones come into play.‎ They are lightweight (compared to a manned airplane or a helicopter), easily transportable by car and capable of flying autonomously at low altitudes with high precision.‎ Such approach assures delivery of accurate survey results, is also safer for personnel and more time-efficient.‎
A GPR mounted on a drone enables to see through the surface of ground, ice, rocks, freshwater, and buildings or through structures at unsafe and hazardous environments without compromising the safety of staff, providing an additional solution for more efficient surveying.‎

Examples of applications include:
- Investigations on uneven ground
- Bathymetry of fresh water
- Geological surveys for soil layer profiling
- Mapping of underground infrastructure
- UXO military mapping
- Glacier surveys

Thanks to the possibility of associating different types of antenna to the drone, it is possible to obtain detailed and high resolution analyzes as well as geological depth investigations.‎

Drone GPR models available:
Drone (DJI Matrix 600 Pro) CBD GPR 200/400/800 MHz
• Use: surface applications and search for small targets.‎

Drone DJI M600 Pro RTK for GPR:
• Data logging computer for GPR (mounted on the drone to log data from GPR and allows to control GPR from the ground station)
• Automatic terrain following option for DJI M600 Pro drone
Allows to follow terrain with very high precision on low altitude using ultrasonic sensor
• UGCS Pro ground station control software license
  
Recommended antennas for DJI M600 Pro Drone:
• SUBECHO-70 (SE-70) antenna
