UAV (1) Using RVOSD and FPV
Loading...
Uploaded by krbosak on Sep 20, 2009
The video demonstrates testing of the IMU autopilot display module when flying in manual mode, known as FPV.
The use of autopilot allows accurate representation of artificial horison and enhanced quality GPS data.
This is only one of several methods to have fun with this autopilot fitted to electric RC plane. Other methods include increased safety of long range manual flights (thanks to automatic return home feature), data logging, aerial photography and amateur area surveillance thanks to automatic loiter after returning home.
The purpose of the tesing was to judge the roll angle in the following conditions:
1. The platform used had no pressure airspeed sensor as it is designed with durability in mind. This makes roll angle estimation much harder.
2. The platform (EasyStar) is using rudder only in order to spare weight of the servos and enhance durability. This guarantees that the turns are uncoordinated (imperfect) and again increasing the difficulty of roll estimation.
3. The flight dynamics is much more violent you should expect from typical rudder-only plane, it was achieved by enlarging the rudder surface 4 times.

@magicmike1122 EasyUAV has flown more than year ago for 80min with lipo3S. 30min was with lipo 3S 2200mAh using very primitive motor. Try it in manual mode using EasyStar without thermals and you will see.

Mike you know nothing. The flight was in manual mode testing IMU resistance to uncoordinated turns up to 4G. In this specific flight the RVOSD was used as display method to make the movie.The autopilot was used for cosntructing Pteryx UAV for example, which is used or making very precise digital world models by the civilians. This actually surpasses capabilities of military drones using just video feed which are mosaicking it with limited success.

@iFlyFPV OSD is On Screen Display. It is only a display. All is flown by a separate autopilot, called FLEXIPILOT. The autopilot can be programmed to fly in total absence of RC signal or when jamming is present. Typically it is programmed so that it returns home anyway since there is are no business interest in flying in full auto beyond RC range.

So if your flying waypoint nav mode, can you program the osd to fly the rest of the waypoints and NOT return home if you encounter loss of signal?

@magicmike1122
this is only a case when autopilot is flown manually showing its output via well known OSD.

look u cant even fly strait w/ that and u just use fpv from hobbywireless w/ rvosd and probaly just a lipo 4 what 30 min of flite? the military has way!!!!!!!!!! better stuff than this
