PRISM uses the Pixhawk 2.1 CUBE Orange flight controller. This autopilot
system is manufactured in Taiwan, and is used by thousands of RPAS around the world.
This system runs the open source ARDUCOPTER Firmware, with widespread providing a
proven reliability record. The flight controller employs built-in redundancy, using 3 onboard
IMUs and 2 processors, limiting single point of failure of the autopilot or
navigation functionality.
PRISM also utilizes dual HERE3 Compass/GPS systems which offer precise GPS
location as well as an external magnetometer for direction and navigation.
In addition, PRISM utilizes a Raspberry Pi Zero-W as an onboard companion
computer. This onboard computer allows PRISM to connect to a WiFi network
for software updates, as well as system level configuration and control.
This RPA is delivered with the EchoSky Mobile radio system running the proprietary
WattsQGC application for flight.This link provides all required communications over a
single, bi-directional, radio signal. The system comprises an air module and ground control
station, and operates on the 2.4 GHz spectrum. The EchoSky Mobile system incorporates
RC control, Mavlink telemetry and HD Video streaming into one compact system

to change from a small quadcopter to a large coaxial drone in moments, with absolutely
zero setup required. This also allows a user to easily service the drone himself, in the
unlikely event that the drone requires a repair to one of its propulsion systems. Not only
that, but this technology allows the drone to display the cumulative flight time for each
individual propulsion system. Lastly, because each propulsion system’s location (Front
Right, Front Left, etc.) is hard-coded into the arm itself, the drone will recognize this,
only allowing the user to arm if all four propulsion systems are identical and plugged into
the correct arm socket.
