RTK Drone Surveying — Precision with GNSS Rovers
How we combine Trimble GNSS Rovers with DJI RTK drones to achieve sub-centimetre survey accuracy for construction, land, and infrastructure projects.
At Drone Solutions Ireland, we combine GNSS Rovers with DJI Enterprise RTK drones to deliver the highest level of accuracy in aerial surveying.
Our workflow begins with establishing Ground Control Points (GCPs) — strategically positioned markers with precisely known coordinates. We use high-precision Trimble GNSS receivers to measure exact coordinates at centimetre-level accuracy, marking points with highly visible black and white targets for identification in drone imagery.
Our DJI Enterprise drones employ Real-Time Kinematic (RTK) technology to achieve centimetre-level accuracy by correcting GNSS errors in real-time. This reduces the number of necessary GCPs while improving efficiency. Post-Processing Kinematic (PPK) further refines accuracy through data analysis after flights.
Trimble services support our operation through equipment calibration, maintenance, technical assistance, and advanced positioning solutions that improve GNSS measurement accuracy across all terrain types.
The combination of GNSS Rovers and RTK drones enables us to deliver survey-grade outputs for construction, agricultural, and land surveying applications — outputs that meet professional engineering standards.
