Comparing Precision of Autopilots for Survey Missions - DJI Phantom 4

Here at SPH Engineering we have a fleet of various drones we use for diverse research and development projects as well as testing new releases of UgCS.

When it comes to using drones for land surveying, mapping or 3D reconstructions, flight precision plays an important role. This is why we decided to test the precision of different drones to see how well they compare to one another. For that we prepared a short photogrammetry mission in UgCS to see how well does the actual flight trajectory correspond to survey lines.

In the first part we tested the DJI Phantom 4 using different turn types: first flight with Stop and Turn, second - Adaptive Bank. See the flight comparison in the video below:


We will try and publish one drone test per week. Next-up will be the DJI Naza-M V2.

Below are the KML files from the test route and the flight paths. You can import and view them in Google Earth.

Well a Phantom 4 must be better than a Naza M V2. How about a Pixhawk 1/2 with a high quality M8 GPS and latest Arducopter?

Phantom 4 is much better than Naza. We already did that test and were surprised by results...

We will test almost all our fleet, we have in operational condition at the moment:

- Mikrokopter Quadro XL
- Microdrones MD4-200
- Kestrel Indago 

- 3DR Pixhawk (Arducopter)

- DJI Naza-M V2 
- DJI WooKong-M
- DJI A2 
- DJI Phantom 3 Pro 
- DJI Inspire 
- DJI Phantom 3 Standard
- DJI Phantom 2
- DJI Phantom 4
- 3DR Iris (PX4)
- 3DR Iris (ArduCopter)
- DJI A3 
- 3DR Pixhawk with RTKite RTK board
- Drotek Dropix on same frame as original 3DR Pixhawk - it will be interesting to see difference between two autopilots with same software (ArduCopter - we should use same version)
- Micropilot MP2128
