# 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.Super lightweight • Durable EPP foam body & wings • Take-off weight: 0.73 kg (1.61 lbs)

18.2 MP still camera • Controlled by eBee RTK’s autopilot • Captures images autonomously • GSD of down to 1.5 cm per pixel Built-in GNSS/RTK receiver • L1/L2, GPS & GLONASS • Onboard RTK corrections at 20 Hz • Upstream corrections at 1 Hz

GNSS antenna • Receives corrections from most leading brands of base station • Absolute X,Y/Z accuracy down to 3 cm / 5 cm • No Ground Control Points necessary

Pitot tube • Measures dynamic & static pressure • Precisely calculates the drone’s air speed

Inherently safe • Shock absorbent foam + low weight = low impact energy • Minimal danger to people & property Green technology • Brushless electric motor • Low noise, low pollution • Re-chargeable lithium-polymer battery

# 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 onhow 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.
