senseFly announces the eBee RTK mapping drone

Product description
The eBee RTK by senseFly is a fully autonomous survey-grade mapping drone (or UAV/UAS). It features a built-in L1/L2 GNSS receiver and is capable of receiving corrections from most leading brands of base station via its supplied eMotion 2 flight control software and ground modem. This ensures the high positional accuracy of the drone’s images without the need for Ground Control Points (GCPs).
The eBee RTK is sold as a standalone solution - comprising the drone itself, eMotion 2 flight planning & control software, and Postflight Terra 3D photogrammetry software (powered by Pix4D). No extra base station purchase is necessary and no additional logger or third-party software are required.

3 ways to work with the eBee RTK

1. Real Time Kinematic
·         Place your base station on a known position
·         Correction data is streamed to the drone via its eMotion flight control software and ground modem (see graphic on previous page)
2. Virtual base station
·         Configure the drone’s eMotion software to receive VRS/Ntrip correction data (internet connection & VRS/Ntrip subscription required)
·         Creates a virtual base station location
·         Correction data is streamed to the drone via its eMotion flight control software and ground modem
3. Post processing
·         Position your base station in a convenient on-site location
·         Its coordinates are set automatically in eMotion 2
·         The base station streams correction data to the drone via eMotion and the ground modem (see graphic on previous page)
·         Post-flight, geotag images with correction data either on-site (requires internet access) or in the office later

Key features
·         Survey-grade accuracy
Absolute orthomosaic / Digital Elevation Model accuracy of down to 3 cm (1.2 in) without the need for GCPs – for less time spent in the field and high precision even in inaccessible areas.
·         Fully integrated workflow
The eBee RTK’s flight planning and control software (eMotion 2) connects to the base station and broadcasts correction data to the rover (eBee RTK) - no additional logger or third-party software required. This software can also be used to apply corrections later via post-processing.
·         Base station compatible
The eBee RTK is compatible with most leading brands of base station, working seamlessly alongside your existing portfolio of instruments.
·         Autonomous
The eBee RTK flies, acquires images and lands itself.
·         Lightweight

The eBee RTK weighs just 0.7 kg (1.5 lbs) –  minimising its power usage (optimizing its flight time) and ensuring the safety of people and objects on the ground.
