Aircraft Cartographer Mini PPK/RTK weighing less than 250 grams
Project of the Aerial Photography Complex with Open Source Software
Overview of the project
We are pleased to present you with an innovative aerial photography complex, developed for creating accurate maps of the terrain and landscape, as well as monitoring vegetation using open-source software. This complex is unique because its aircraft weighs less than 250 grams, making it extremely mobile and efficient in application.
Main components of the project:
Open source software:
OpenDroneMap: Creation of maps and topography from photographs.
QGIS: Raster transformation for vegetation analysis (NDVI).
SputnikAgro: Conversion of vegetation maps into a format suitable for sprayers and fertilizer spreaders.
rtklib: Determination of exact coordinates of the photos.
ardupilot: Control of the drone, programming flight, auto-start, and auto-landing.
Mission Planer: flight mission planning
openTX: Controller radio programming software.
Raspberry Pi OS: Recording photographs and data to calculate accurate photo coordinates.
ELRS: Two-way communication with the drone, telemetry.

Currently, extensive flight tests are being conducted; a report on which will be published later. For easing and accelerating map creation, there is an online service available. Upload your files, and receive the map in the shortest time (approximately half an hour).
Advantages:
The weight of the aircraft allows free use in many countries without registration or permits (direct visibility, height up to 122 meters, no people in the flight zone).
Perhaps in another country you won’t have to wait months for permission to use.
Fully open-source code - security and openness.
Speed and ease of obtaining maps when using a cloud service.
Mobile usage - total weight of the kit for one working day (6 hours of flight - 12 square kilometers) is only 2.5 kg, including the aircraft, 6 batteries, radio control, smartphone, rubber catapult, and case. Dimensions: 25X40X10 cm.
