Drone Surveying

Drone surveying uses UAVs equipped with imaging and sensing technology to capture high-resolution aerial data for mapping, measurement, and analysis.

Drone surveys achieve high accuracy, often within centimetres, making them ideal for topographic mapping, infrastructure assessments, and detailed planning.

Drone surveying is beneficial for industries such as construction, land development, energy, infrastructure, and environmental management.

Yes, drones can safely survey areas that are difficult or unsafe for ground crews, including rugged terrains, elevated structures, and environmentally sensitive locations.

Drone surveying is faster, safer, and more cost-effective, providing high-resolution data without the need for extensive ground-based equipment or labour with the same or better levels of accuracy

Our drone surveys provide orthomosaic maps, 3D models, point clouds, thermal imaging, and digital elevation models (DEMs), tailored to your project needs.

Yes, drone surveys reduce labour and equipment costs while providing faster results, making them a cost-efficient solution for a wide range of projects.

Drones can operate in various weather conditions, but high winds, rain, or fog may affect data quality. Our team carefully plans surveys to ensure optimal conditions.

RTK, or Real-Time Kinematic positioning, is a high-precision positioning technique used in applications requiring centimetre-level accuracy, such as surveying, mapping, and drone operations. It enhances the accuracy of GPS (Global Positioning System) data by using a fixed reference station to correct positional errors in real time. RTK operates by combining satellite data from GPS or GNSS (Global Navigation Satellite Systems) with correction signals from a fixed reference station. Here’s a step-by-step breakdown:

1. Satellite Signal Collection

• • The rover (e.g., a drone, mobile receiver, or survey instrument) and a fixed base station collect satellite signals simultaneously.
  • These signals contain raw data about position, time, and velocity.

2. Reference Station Correction

• • The fixed base station, whose location is precisely known, compares its calculated GPS position (based on satellite data) with its actual position.
  • Any discrepancies, caused by errors like atmospheric interference or satellite clock inaccuracies, are computed as correction data.

3. Real-Time Data Transmission

• • The base station transmits correction data to the rover in real time via radio signals, cellular networks, or the internet.

4. Error Correction at the Rover

• • The rover combines the correction data from the base station with its own GPS data to calculate its precise position.
  • This process reduces positional errors from several metres (typical for standalone GPS) to as little as 1–2 centimetres.
