Drone Based Water Sampling

At Eiredrone, we conduct water sampling with cutting-edge drone technology, eliminating the need for traditional and costly methods. Our advanced drones can access difficult-to-reach areas, making water sampling quick, efficient, and cost-effective.

Equipped with a sampling tube that holds up to one litre of water per flight, our drones can collect samples precisely and efficiently. To ensure stability and safety during low-altitude flights over water, we utilize True Terrain Following (TTF) technology.

An onboard computer controls the messenger release device, enabling a fully automated process of remote water sampling. This automation streamlines the sampling process, ensuring accuracy and reliability while minimizing human intervention.

With drone water sampling solutions, you can access remote water bodies without the need for boats, crews, or extensive safety equipment, making water sampling faster, safer, and more economical, providing clients with valuable data for environmental monitoring, research, and resource management.

Drone Bathymetry

Bathymetry is the act of using a sonar system to map the depth of a river bed, lake bed, or even sea bed. Using a series of two dimensional profiles, a three dimensional representation of the river bed is obtainable providing a wealth of information including:

- River Channel Depth Mapping
- Waterway Scour Identification
- Submerged Debris location
- Soft Sediment Depth Indications (Duel Frequency Echosounder)
- Fresh water reservoir surveys
- Support primary Sensor surveys

Drone bathymetry involves suspending an echosounder from a drone equip with some very smart software. This software makes calculations based on the drones position, the echosounder position, and the real time telemetry that the drone is recording, to create instant corrections. These corrections provide you with clear data for decision making.

The key benefits of using drone bathymetry are:
- Access hard to reach locations/no points of entry
- Seaweed, debris, mechanical pollution (Grasshop)
- Drinking Water reservoirs (no boats)
- Fast set-up, easy deployment
- Good repeatability
- Excellent maneuverability

Drone Ground Penetrating Radar

Ground Penetrating Radar (GPR) works by sending a small pulse of electromagnetic energy into the ground and records the strength and time required of a return signal. When we scan an area we use a series of pulses to create an ‘image’ of what is underground. This ‘image’ is created by the difference in Relative Dielectric Permittivity (RDP) of the material that the electromagnetic pulses travel through. As the electromagnetic pulses travel from one material to another, part of the energy gets reflected. The GPR unit sees these reflections of energy and records them as the drone flies.

The larger the difference in Relative Dielectric Permittivity, the stronger the reflection produced. Generally heavy and wet soils have a very high RDP, and therefore prove troublesome for GPR units. Drone based GPR is much more suited to dry soils, dry sands, rock, and concrete. Their low RDP values (5-6) means that they do not conduct electricity easily, increasing the penetration depth of the electromagnetic pulses.

GPR units operate at different frequencies. The higher the frequency the higher the resolution of the scan but the lower the penetration depth. In contrast, lower frequency GPR units give lower resolution scans but penetrate deeper into the earth. A high frequency GPR unit might be used to detect pipes buried in the ground at only 0.5m in depth, and a low frequency GPR may be used to determine the depth bedrock under peaty soils.

Applications typically suited to drone based GPR are:

- Utilities Mapping – pipe detection and backfill identification
- Mountain Rescue – Avalanche Support for Search & Recovery
- Archaeology Surveys – Buried Artifacts and architecture search
- Land Conservation – Soil analysis, cavity, and sinkhole analysis
- Geological Studies – Rock thickness and state of structure
- Waterway Conservation – Fresh Water Bathymetry / Infrastructure Mapping
- Criminal Investigations – Buried remains location
- Artic Surveys – Snow, Ice & Permafrost thickness measurements

Key considerations and limitations of drone based GPR:

- ½ the signal strength of any flown GPR is lost though ground surface reflection which means heavy soils are not ideal.
- Heavy soils (clay and loam) are not at all friendly to airborne GPR. Wet heavy soils will provide poor results.
- An RDP less than 9 is required for effective results. Ideal UK soil conditions are dry sandy soils.
- Fresh water Bathymetry with airborne GPR is extremely effective and useful. However, it must be remembered that airborne GPR will not work in salt water.

Drone Magnetic Survey

Drone magnetic surveys are completed by suspending a magnetometer below a drone. Using true terrain following technology, we can glide over undulating terrain at very low altitudes to capture consistent data.

Magnetometers work by sensing differences in the earths magnetic field caused by subsurface objects/materials. The differences in the earths magnetic field are due to magnetic susceptibility which is directly proportional to iron content.

Drone magnetic surveys compliment many industries and disciplines:

- Geology (sediment analysis)
- Archaeology (buried objects, features, & architecture)
- Civil Engineering (utility mapping)
- Land Remediation & Redevelopment (area clearance)
- Mineral Exploration (iron, copper, tin etc.)
- Unexploded Ordinance (UXO) Detection (Landmines, IED, unexploded bombs & ammunition)

Although drone magnetic surveys will not replace the accuracy achieved by cart surveys, recent developments in technology has made the results comparable in some applications. Many key benefits of drone magnetic surveys include:

- Accurate Fast data collection over all terrains
- Smooth data collection without sudden sensor movements (due to uneven ground)
- Surveys over water and boggy terrain (unsuitable for cart)
- Surveys over dangerous land areas (mine fields)
- Surveys over slopes and precarious land features (safety perspective)
- New technology enables comparable results to cart based systems
- Provides scout capability to quickly evaluate large areas economically
- Survey lines (using RTK precision)

Drone Methane Detection Surveys

Eiredrone can provide drone methane detection surveys using the some of the most technically advanced drone equipment on the market. True terrain following capabilities allows the drone to effortlessly glide over challenging terrain while maintaining a consistent and safe distance above the ground. This flying method produces accurate and repeatable drone methane detection surveys.

Applications of drone methane detection surveys include:

- Chemical Facilities
- Oil Refineries
- Gas Terminals/Processing plants
- Petrochemical Facilities
- Gas Pipelines/NetworksCompressor stations
- Underground Gas Storage Facilities
- Landfill SitesBiofuel Generation Facilities
- Gas Power Stations (SCPP/CCPP)
- Anaerobic Digestion Generation Plants

The methane detection payload is a lightweight solution. On average an area of 100 sqm can be covered in 13mins using a DJI M300 RTK drone.
