“Multirotor UAV in project 14.B37.21.1243” Vyacheslav Barbasov, Pavel Orlov

UAV developed in MIIGAiK
SCB “Impulse”
SCB “Krechet”

SCB ”Krechet” is working on several platforms for use in cartographic monitoring

Multirotor UAV, which is developed in SCB MIIGAiK «Krechet», – octocopter «Dreadnought». This drone can be used to receive snapshots, applicable in map (or site plan) creating/updating, forming of digital terrain model, making 3D-models of buildings and objects, thermographic maps, panoramic surveying and also monitoring of natural and manmade emergencies development.

Functions & elements of ground control
When we use multirotor UAV in cartographic monitoring, it must be considered as a complex with its equipment (instrumentation) and payload. Its called UAS – Unmanned Aircraft System. UAS consist of payload and ground control.
What is it for?
- Automatic flight control;
- Flight navigation;
- Flight task input and processing;
- Setting up a wireless link with an operator;
Data receiving, processing and storage
(Video and Telemetry);
- Input of UAV control signals.

Data, which is receiving by operators

What can you find in UAV payload?
- Digital camera (including Video camera)
- Thermographic camera
- IR-camera
- Radiolocation equipment (Sonar)
- Geiger counter

The ways of multirotor UAV usage in environment monitoring:
Cartographic monitoring
Topographic survey
Multispectral survey
Thermographic survey
Geology
Cadastre (stereo image)
Emergency control
Tasks of agro-industrial complex
Snapshots for 3D modeling
Agriculture: control of farms & fields condition
Ecological monitoring:
- radiation;
- chemical pollution;
- bacteriological pollution.
