SENSORS

High-Resolution RGB Cameras

Standard cameras for visual inspections.

Thermal Cameras

Detect heat anomalies indicating potential issues.

LiDAR

Creates detailed 3D models of structures and terrain.

Multispectral & Hyperspectral Sensors

Analyse material properties and detect issues not visible to the naked eye

Ultrasonic & Acoustic Sensors

For non-destructive testing (NDT) and detecting structural defects.

High-Resolution RGB Cameras

High-resolution RGB (Red, Green, Blue) cameras capture images in high detail and colour fidelity, utilizing three colour channels to represent images similar to how the human eye perceives colour. The RGB Camera is an essential and most used tool on our UAV’s.

Photography and Videography

They provide high-quality images and videos, essential for professional photography, filmmaking, and content creation.

Scientific Research

Used in fields like biology and astronomy to capture detailed images for analysis and study.

Surveillance and Security

High-resolution cameras enhance image clarity, making it easier to identify faces, license plates, and other details.

Industrial Inspection

Used to inspect products for defects and ensure quality control in manufacturing processes.

Virtual Reality and Augmented Reality

Provide detailed environmental mapping, crucial for creating immersive experiences.

Thermal cameras

Thermal cameras, also known as infrared cameras, detect infrared radiation (heat) and convert it into an image that can be analysed. These cameras are useful in various applications.

Security and Surveillance

Detect heat signatures of intruders or pests in complete darkness, fog, or smoke.

Industrial Inspection

Identify overheating equipment, electrical faults, or insulation issues.

Building Inspections

Detect heat leaks, moisture intrusion, and structural issues in buildings.

Firefighting

Locate hotspots in fires and identify trapped individuals through smoke.

Research and Development

Study thermal properties of materials and systems.

LiDAR

LiDAR (Light Detection and Ranging) is a remote sensing method that uses laser light to measure distances to objects. It creates precise, three-dimensional information about the shape and surface characteristics of the Earth and other objects. Here’s an overview of LiDAR and its applications.

Topographic Mapping

Used to create high-resolution maps of terrain and surface features.

Forestry

Assesses forest structure, biomass, and health by analyzing tree canopy and ground surface data.

Urban Planning and Management

Maps urban environments for infrastructure planning, construction, and maintenance.

Archaeology

Reveals hidden structures and features beneath dense vegetation without disturbing the site.

Coastal and Floodplain Management

Maps coastal zones and floodplains to monitor erosion, plan flood defenses, and manage resources.

Mining

Measures stockpile volumes, maps mine sites, and monitors environmental impact.

Agriculture

Analyses crop health, soil properties, and topography for precision farming.

Disaster Management

Assesses damage and plans recovery efforts after natural disasters like earthquakes, hurricanes, and floods.

Multispectral Sensors

Multispectral and hyperspectral sensors are advanced imaging systems that capture data across multiple wavelengths of light, beyond the visible spectrum. They are crucial for applications requiring detailed spectral information.

Agriculture

Monitor crop health, soil properties, and irrigation needs. Identify plant stress and disease.

Environmental Monitoring

Track changes in vegetation, water quality, and land use. Detect pollutants.

Forestry

Assess forest health, monitor deforestation, and manage forest resources.

Geology

Map mineral deposits and study soil composition.

Water Resource Management

Monitor water bodies, assess turbidity, and detect algal blooms.

Urban Planning

Analyse land cover and land use changes in urban areas.

WORKFLOW

Our workflow involves several stages, from planning and preparation to data analysis and reporting. Here’s an overview of a typical UAV operations workflow for most applications

Mission Planning
Define the purpose of the UAV mission (e.g., surveying, mapping, inspection, monitoring).
Identify specific goals and deliverables.
Site Assessment
Assess the area to be surveyed or inspected.
Identify potential hazards and obstacles (e.g., power lines, trees, buildings).
Regulatory Compliance
Obtain necessary permissions and clearances from aviation the CAA.
Ensure compliance with local regulations and airspace restrictions.
Flight Planning
Design the flight path using mission planning software.
Define waypoints, altitude, speed, and overlaps for image capture.
Risk Assessment
Evaluate potential risks and develop mitigation strategies.
Create a contingency plan for emergencies.
Weather Check
Check the weather forecast to ensure suitable flying conditions.
Plan for alternative dates in case of adverse weather.
Pre-Flight Preparations
Inspect UAV and payload for any damage or issues.
Ensure batteries are fully charged and spares are available and calibrate sensors and cameras if necessary.
System Setup
Load the flight plan into the UAV's autopilot system.
Configure camera or sensor settings (e.g., resolution, frame rate).
Safety Briefing
Brief the flight team on the mission plan, roles, and responsibilities.
Review emergency procedures and communication protocols.
Flight Execution
Set up a safe takeoff and landing area.
Mark the operation area with signs or barriers if needed.
Pre-Flight Checks
Perform pre-flight checks as per the UAV's checklist.
Conduct a short test flight to ensure all systems are functioning.
Flight Operations
Launch the UAV and monitor its progress throughout the flight.
Ensure real-time monitoring of telemetry data (e.g., altitude, speed, battery level) and maintain visual line of sight (VLOS) or use a visual observer if required.
Data Collection
Capture images, video, or sensor data as per the mission plan.
Ensure data quality by periodically checking the feed.
Post-Flight Procedures
Safely land the UAV and power it down.
Inspect the UAV for any damage or issues post-flight.
Data Retrieval
Retrieve data from the UAV's storage device.
Verify data integrity and completeness.
