1. Drone preparation
1.1 First steps before work
DJI Mavic 2 Pro Topodrone PPK – is a ready-to-fly geodetic survey solution which is based on DJI
Mavic 2 Pro drone. It is strongly recommended to learn DJI M2P manual first, you can find it on the official
web-site: https://www.dji.com/uk/mavic-2/info#downloads
Correct preparation of the drone means following exact rules to ensure flight safety and the best
orthophoto or 3D-model quality. Flight safety – is the main basis of all our solution.
1. Checking. All components of the drone must be in a condition: no damages, cracks or malfunctions.
It is needed to carefully inspect blades, motormounts, motors, arms, gimbal, micro-sd cards, cables
and connectors, especially if you had drone in a public use. Always check your DJI Mavic 2 Pro
Topodrone PPK before large orders and far business trips.
2. Charging. You should charge all batteries of the drone, remote controller (RC) and mobile device
up to 100%. Never use DJI Intelligent Battery which is charged lower than 90%, especially if battery
has started its storage discharging. It can cause premature termination of the flight mission.
3. Exploring. Before move to the working area, explore locality in a
on-line geo-services like DJI GEO, AirMap, and PilotHub, to
provide yourself more knowledge about places and objects located
nearby. It is not allowed to fly in No-Fly-Zones: airports, prisons,
sports stadiums. Military bases, state institutions, objects of
strategic importance (CHP, hydroelectric power plants, nuclear
power plants, etc.) are particularly dangerous, but they are not
marked at GEO-services. Electricity transmission lines, located at
the place you need to capture, can cause radio and magnetic
interference during the flight.
4. Setting. In the DJI Go 41 App set all parameters for comfort flying in a manual mode:
1. Distance limit – “turn off” value is recommended
2. Maximum Flight Altitude – 500 meters2 value is recommended
3. Return to home altitude – 100 meters or higher value is recommended. Anyway it changes
during the mission planning in the other apps.
4. RC MODE settings – changes axes of the sticks, value 2 is strongly recommended
5. EXP tuning – provides you control drone more accurate, 0.10 value is recommended
6. RC signal lost – action which drone would make if lost RC signal. Value “Return to home” is
recommended
7. Low battery warning – set at the minimum, 20% value is recommended3
NOTICE 1. DJI Go 4 App is the basic application for DJI Drones. You could not set several parameters
via other apps. It is recommended to make manual flights using DJI Go 4 App.
NOTICE 2. In some countries maximum allowed flight altitude for UAV is 120 meters. Setting 500
meters value in maximum flight altitude menu provide drone follow the terrain, flies higher than 120
meters from the altitude of home point, but not from the terrain.
NOTICE 3. If area of photographing is located far from you (more than 1 km), increase this value to 30%
NOTICE 4. Camera settings described in paragraph 1.3 of this manual.
