horizontal deploy of a vertical tilt vector

Posted by Gloria Peralta at July 27. 2010

Hi to everybody,

Before I wrote this email I checked all the topics posted in deployment forum, but I couldn't find the right topic that solve my doubts.

I'm doing some velocity measurements very close to the bottom floor. To do so I deployed horizontally a fix vector on a H frame, orientated the X tip looking up and choosed a XYZ coordinate system. As far as I understand, my results should represent Z with the same direction as the vector canister (positive values from the tip to the end bell), X is now orientated up and Y is 90ยบ left with respect to X and Z.

Is this right? or  Do I have to change completely the calculations and rotate the coordinate system? 

Thanks in advance,

Gloria

Hi Gloria,

You've got it right for XYZ. If your tilt sensor and compass are installed for a vertical orientation of the pressure canister, don't try to convert to ENU coordinates as the readings from them will be wrong.
