ArduPilot plus Parkzone Radian without Themopiles or IMU

Posted by Philip Geßner on December 5, 2010 at 12:37pm
Hi,

I'm pretty new to building an UAV but I've just bought a Parkzone Radian and come across the question whether it could fly autonomously with an ArduPilot plus an EM406 GPS without using Thermopiles or an IMU.

I might as well add an airspeed sensor in order to get constant airspeed but I have to sort out this question first.

Thanks in advance,
Philip Geßner.

    You don't need ailerons. The EasyStar has only en elevator and rudder and is used with ardupilot. Just as you would steer to compensate for when the nose dips, or a side wind catches your plane, ArduPilot would also try to *correct* the orientation. However it would have to know its orientation in order to do this - thus the IMU or thermopiles. I hope this helps.

    From what I understand it would not work without using sensors to help the ArduPilot determine its pitch and roll. The thermopiles or IMU are used for that very purpose.

    I doubt it. You'd need unbelievable intrinsic stability to fly that way. Pretty much only a blimp or microlight could do it, I reckon.
