eBee RTK

The survey-grade mapping drone

Capture aerial photography to produce orthomosaics & 3D models with absolute accuracy of down to 3 cm - without Ground Control Points.

3 reasons to choose the eBee RTK

Survey-grade accuracy

Absolute orthomosaic / Digital Elevation Model accuracy of down to 3 cm (1.2 in) without the need for GCPs – meaning less time spent in the field and high precision in even the most inaccessible areas.

Fully integrated workflow

The eBee RTK’s supplied flight planning & control software (eMotion) connects to the base station and broadcasts correction data to the rover (eBee RTK) – no additional logger or third-party software required.

Compatible with existing base stations

The eBee RTK is compatible with most leading brands of base station, working seamlessly alongside your existing portfolio of instruments.

3 ways of working with the eBee RTK

Local base, known position

  • Place your base station on a known position
  • Enter the base station’s coordinates and characteristics into eMotion
  • eMotion streams correction data to the drone via the ground modem

Local base, unknown position

  • Position your base station in a convenient location
  • eMotion calculates your base’s approximate position
  • eMotion streams correction data to the drone via the ground modem
  • Correct your base’s position in post-processing to achieve a high level of absolute accuracy

Virtual reference station

  • Configure your drone’s eMotion software to receive VRS/NTRIP correction data (internet connection and VRS/NTRIP subscription required)
  • eMotion streams correction data to the drone via the ground modem

01. Plan your flight

senseFly’s intuitive eMotion software makes it easy to plan and simulate your mapping mission.

Plan: Import your preferred base map and define the area you want to cover. Then specify your required ground resolution (with a GSD of down to 1.5 cm), and image overlap.

eMotion automatically generates a full flight plan, calculating the eBee RTK’s required altitude and displaying its projected trajectory.

Configure: If you know your base station’s coordinates, enter these into eMotion. If not, eMotion will calculate your base’s approximate position. Or you can configure eMotion to receive VRS/NTRIP corrections.  eMotion then streams correction data to the eBee RTK via the senseFly USB ground modem.

Simulate: To ensure your mission’s success, run a virtual flight that simulates wind strength and direction. Then make any flight plan updates required and prepare to launch.

02. Fly

Launch: To launch the eBee RTK, shake it three times to start its motor, then throw it into the air. The artificial intelligence built into the senseFly autopilot continuously analyzes data from the Inertial  Measurement Unit and the onboard GPS to control every aspect of its flight.

Monitor: Using eMotion ground station software you can view the eBee RTK's flight parameters, battery level and image acquisition progress in real time.

Control: Made a mistake with your planning? You can reprogram your drone’s flight plan and landing point during its flight.

03. Create

Process: Use professional photogrammetry software such as Pix4Dmapper (optional) to process your flight’s photos into geo-referenced orthomosaics, 3D point clouds, triangle models and digital surface models (DSMs), in just a few clicks.

Trust: With the eBee RTK’s GSD of down to 1.5 cm, relative orthomosaic/3D model accuracy of 1-3x GSD, and absolute horizontal/vertical accuracy of down to 3/5 cm (without GCPs), you can have full confidence in the accuracy of the outputs you produce.

Analyse data & produce deliverables

Once you have created your orthomosaic and 3D model, it's time to put this data to work - for example by measuring distances, taking cross-sections, and extracting volume data using software such as Pix4Dmapper (optional with every senseFly drone). Or exporting to third-party software to add GIS data or create custom maps.
