Today Holger coupled his Microcopter with a GPS Sensor. He did this in a quite simple way and the used closed-loop control will swing up. That doesn't mean it's not impressive! It already shows how it would work. Please note how often Holger is not controlling the Microcopter! Long times it flys autonomiously!
May I present Holger's show:

In my last article I talked about Holger's Microcopter which uses a barometric sensor to measure air pressure to stabilize it's altitute. You can imagine that air pressure only differs minimal between a place 1m higher and another place 1m lower. So the sensibility of the air pressure sensor has to be very high to be able to recognize small altitude changes.
Such high sensibility has it's pitfalls and it seems to be fun to test them out. Holger found out that opening a door while flying indoors already results in such a big air pressure change that the Microcopter would race through the floor or roof if the linear acceleration sensors would not compensate!
Holger released a new video showing his indoor experiments...

In my last article I wrote about the inherent stability problem of QuadCopters and how closed loop control of modern electronics is able to compensate and stabilize it to make it possible to fly and steer such a construct.
Flying a QuadCopter while there is a storm at first sounded impossible to me.
Holger, an inventive guy from the QuadCopter Forum - inventor of the Microcopter - was crazy enough to try and test his Microcopter in a storm. Holger's Microcopter uses barometric sensors to measure air pressure which are used to stabilize the Microcopter's altitiude.
Looking at the movie one realizes, that Holger's Microcopter is up to the challenge and Holger is able to fly it without problems:
