UAV with RTK eliminates ground control

Sirius Pro UAV

MAVinci’s latest offering to the Unmanned Aerial System (UAS) market, the Sirius Pro UAV, offers the same 5cm accuracy as a Sirius Classic without the need for ground control points (GCPs).

Traditionally, ground control points have been required for UAS modelling applications. This new system removes the need to set up GCPs altogether, saving time, reducing cost, and increasing efficiency. It also allows areas that are difficult to access, hazardous, or very large to be aerially surveyed.

“Setting out ground control can often take more than 50% of the total project time for an aerial survey,” explained Gavin Docherty, UAS Product Manager for MAVinci’s Australasian distributor, Position Partners. “By removing this step in the process, the Sirius Pro delivers the same accuracy and reliability of data with ultimate convenience for the user.”

The Sirius Pro features Topcon Positioning System’s high precision GNSS technology, with an on-board Topcon 100Hz dual frequency geodetic GNSS receiver to deliver RTK accuracy.

The MAVinci Connector then works as an RTK base station, which transmits corrections to the GNSS receiver on-board, enabling high precision surveying in real-time.

The Sirius Pro UAV essentially puts ground points in the air, eliminating the need for manual set-out on the ground – which could be especially useful for mining applications.

Mine surveyors face the challenge of conducting surveys, reconciliation, and geological work in active mining areas with working heavy machinery. This often requires the surveyor to get approval to shut down plant on site for ground control set-out, adding lengthy delays to a survey.

Sirius Pro customer Matt Ewing, Director of UAS surveying firm Airmap3D, has experienced the benefits first hand. “Organising the logistics to get out and set out the ground control points was a long process that would add up to a whole day to each job,” he said.

“But now I can deliver a job to a mine site, from start to finish including data processing, in half a day with the same if not better accuracy than the Classic model.”
