The survey-grade 

mapping drone

3 reasons to 

choose 

the eBee RTK

01. 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.

02. 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.

03. 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.
Out of the box and ready to fly

The eBee RTK is supplied in its own carryon sized case, which contains all the 

components you need to take to the skies. 

This includes download keys for our eMotion 

flight planning software and Postflight Terra 

3D photogrammetry software.

To launch the eBee RTK, simply attach 

its wings, shake it three times to start its 

motor, and 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.

3 ways of working with the eBee RTK

The eBee RTK is a highly flexible system. It can 

be used in either of three ways, depending on 

how you prefer to work and your access to incountry correction data networks.

Whichever method you choose, no additional 

base station purchase is necessary since the 

eBee RTK is compatible with most leading 

brands of survey-focused base station.
· 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

· 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 postprocessing to achieve a high level of 

absolute accuracy

· 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

Plan & control 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 projec ted 

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.
Create geo-referenced maps & models 

Process: Use Postflight Terra 3D professional 

photogrammetry software, supplied with 

every eBee RTK, to process your flight’s 

photos into geo-referenced 2D orthomosaics, 

3D point clouds, triangle models and Digital 

Elevation Models (DEMs), 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.
