Unmanned Aerial Systems Sensor Placement
In the world of Unmanned Aerial Systems (UAS) the
consumer has a wide range of choices and uses.
Uses range from aerial photography to First Person View (FPV) racing and
the choices may seem endless. This paper
will focus on my two favorite systems for use in aerial photography and FPV
racing as well as describe the many sensors used on each system and their
purpose.
Aerial
Photography
In the world of aerial photography, the consumer must
determine what type of camera system they wish to use. In one case you could simply use a gimbaled
GoPro camera and in another case you could use your own DSLR camera. For those wishing to produce both aerial
photography and aerial video the DJI Spreading Wings S1000+ is a great choice.
The Spreading Wings S1000+ has the capability to fly your
personal DSLR camera such as the 5D Mark III from Canon. Coupled with the DJI A2 flight controller
which has built in IMU, radio receiver, and GPS receiver, the S1000+ has
intelligent orientation control, point of interest, landing gear control, auto
return to home, and a fault detection capability in the event of a motor
failure. This sensor is mounted
centrally to the system with the GPS antenna mounted on the top of the system
for clear line of sight with satellites (DJI.com, n.d.).
As mentioned, the S1000+ has retractable gear. This function coupled with the Zemuse Z15
gimbal allows for full 360-degree unobstructed freedom of you DSLR camera. The S1000+ utilizes a 2.4Ghz full HD digital
video downlink system called Lightbridge.
This allows to user to view what the camera sees allowing for the best
viewing angles and video capture. This
system costs all in at around $4,500.00 US.
For the user that wishes to get into the professional aerial photography
business, the S1000+ provides professional grade sensors and control (DJI.com,
n.d.).
First
Person View Racer
For the consumer wishing to get into the hobby
of FPV racing, there again are many options to choose from. A new emerging technology is the capability
of the FPV racer to tilt its rotors.
This means that in high speed forward flight, the camera system mounted
on the system is not looking at the ground.
One of these FPV racers with this capability is the Walkera Furious 320.
There are several Furious 320 packages to choose from;
specifically, the GPS Edition 2. This
package includes the DEVO-10 radio transmitter, 1080p camera, OSD, and
GPS. The camera sensor on the 320 is
placed on the nose of the racer. This
allows for the best FPV and the GPS antenna and sensor are mounted on top of
the racer for best GPS signal reception (Walkera.com, n.d.).
With the Furious 320, GPS signals are used to both
navigate and return to a known location as well as continually compute the
remaining battery life and the distance it needs to fly back to the home
point. All in and ready to fly, the
Walkera Furious 320 costs $609.00 US.
For a great FPV racing experience, the Furious 320 provides modern
technology, professional design, and quality sensors usage (Walkera.com, n.d.).
