Topcon Positioning Group and MAVinci GmbH have released the latest version of the Sirius Pro surveying UAS (Unmanned Aerial System) program, designed to be compatible with existing RTK (real-time kinematic) base stations or NTRIP (network transport of RTCM data over IP).

“By connecting an external base station, Sirius Pro will receive the RTCM correction signals and deliver 2-5 centimeter accuracy without using ground control points,” said Eduardo Falcon, executive vice president and general manager for the Topcon GeoPositioning Solutions Group. “When you have mobile Internet on your site, you can achieve the same accuracy even without a local base station using NTRIP.”

Sirius Pro is designed to deliver orthofotos and three-dimensional elevation models with a high absolute accuracy of 2-5 centimeters without using ground control points. “Combining MAVinci‘s precision timing technology with Topcon sub-centimeter grade L1/L2 GPS/GLONASS RTK receivers, this robust system stands up with a clever solution that helps in the realizing of projects in a better and faster way,” said Johanna Claussen, CEO at MAVinci.

For users who do not have an RTK base station, an internal base station add-on for the Sirius Pro is available. “It upgrades the Sirius Pro to its full functionality: Use of an internal or external base station depending on your needs,” Claussen said. “This add-on is available anytime via Internet without changing your hardware.”

Sirius Basic is an entry-level solution for UAS surveying, and delivers orthofotos and 3-D elevation models. The system is designed to offer high-accuracy when using ground control points. “Sirius Basic offers you full flexibility,” said Falcon. “It can be upgraded to Sirius Pro via an Internet update later on — no hardware change is necessary.”

The system will be available at the Intergeo trade show for geodesy in October and thereon.  The Topcon and MAVinci UAS was first introduced at Intergeo 2013 for the European market and was recently made available in the North American market.
