I'm interested in using the Horizontal IR sensor from the
Paparazzi project in an amateur rocket. My intent is to use the two
axis Horizontal IR sensor to control servos that will position a motor
attached to a gimbal. The rocket would fly perpendicular to the
horizon and there would be no course guidance.
I am assuming that pins 1 and 4 supply a positive or negative
variable voltage that relates to the direction and angle of bank on each of the two axes. Is there a document that explains that in
detail? Is this voltage constantly supplied? Could someone confirm this is the case?
I have been told these sensors may not work at high altitudes. I assume this might be because the 'image' seen by the sensors will become proportionally more sky as altitude increases and thus, the difference between the opposed sensors might become less. Is this the case? Is there some other reason the sensors become less effective at altitude?
