and the number of satellites the device is communicating
with at any given time.
The MEMS gyroscopes apply MEMS vibrations to the
problem of interpreting the rate of change of the angle of
the UAV. Similarly, the MEMS accelerometers gauge the
acceleration of various forces related to the UAV, including
The magnetoresistive sensors measure changes in
the Earth’s magnetic field that would affect the position
of the UAV. The barometric sensor collects information
about the atmosphere that may be useful in adjusting
thrust to maintain the heading or position. In particular,
it controls craft altitude, enabling the UAV to hold position
while indoors and wherever it may not be able to lock on
Together the UAV’s many sensors provide information
that the onboard processor interprets to control or respond
to roll, pitch, and yaw.
The Cameras (Video and Stills)
The remote controlled helicopter packs a payload with
a wireless video and still camera for aerial surveillance.
Through video monitor enabled sunglasses, the
Draganflyer’s operator sees what the camera sees, putting
human eyes in the sky. The HD digital video camera takes
clear and detailed moving images in digital TV presentation
quality (1080p), with a resolution of 1920 x 1080 pixels
and a frame rate of 24 fps (frames per second).
The UAV transmits live video via 5. 8 GHz OFDM
wireless video and is recorded to Secure Digital High
Capacity memory cards. The UAV streams real time video
from the copter to a pair of video goggles and a recording
device via a handheld controller.
Optional camera payloads include the Panasonic Lumix
DMC-LX3, the Panasonic HDC-SD9, the Watec WAT-902H2

The Draganflyer X6 has applications in law
enforcement, government, and the military, as well as in
real estate promotion and assessment, job site inspection,
wildlife photography, filming live action product demos for
promotional purposes, news reporting applications, and
many others. The Ontario Provincial Police, for example,
used the X6 to gather visual data about a homicide that
occurred in a rural area near Kenora last February. This was
a first in domestic policing in North America, according to a
Draganfly press release. Since then, police in Saskatoon
