Top 10 Hints for Designing Drones #4:

RF is your enemy. Both your GPS receiver and your datalink are sensitive to RF interference. RF interference will increase the time it takes for your GPS receiver to lock, and increase the likelihood that you lose lock and reduce your GPS receiver's position accuracy. Note that RTK (or carrier phase) GPS receivers are especially …

It seems that everyone is working on some sort of transitioning UAV these days. Combining a fixed wing aircraft and some sort of multirotor seems to be the thing to do. The resulting vehicle combines the multirotor's ease of takeoff and landing with the endurance of a fixed wing UAV. There are two main types …

It's hard to cover all the ‘what ifs’ but once your system is in the market, how well you cover all the exception cases will play a large role in determining your …

An airframe that isn't stiff enough will allow its arms to flex, which in turn changes the orientation of the motors. This makes control more difficult and it will increase …
