Sensor placement is a critical design decision that is
based on the objective that an unmanned system will be tasked to perform. For
this assignment, I had to choose two commercial UASs that are currently
available for purchase. One will be utilized to provide aerial photography
services to include full motion video and still pictures below 400 feet Above
Ground Level (AGL). The second UAS will be used as a First Person View (FPV) to
compete on a racing circuit.
First and
foremost on this aircraft is the top of the line camera that can run at up to
30 frames per second (FPS) in 4k mode, or up to 60 FPS in 1080p HD. This camera can also shoot 12 Megapixel still
images too. The camera mounts to the
aircraft on a 3-axis 360 degree rotating gimbal.
The developers of the Inspire wanted to
maximize the ability of the gimbal, and so they designed the aircraft to drop
the body (and therefore the belly mounted gimbal and camera) after takeoff
(Figure 2). This raised the quad’s
landing gear well above the field of view of the camera to truly provide
unobstructed views.
An optional camera (like a
GoPro) can also be installed on the top of the platform.
One of the key features of this model over
previous Runner 250s is the GPS system, providing “return to home” and
“altitude hold” functions for increased stability (Dronewallah, 2015).
