From Wikipedia, the free encyclopedia
Paparazzi is an
open-source
autopilot system oriented toward inexpensive
autonomous aircraft.
[1]
Low cost and availability enable hobbyist use in small
remotely piloted aircraft .
[2] The project began in 2003,
[1] and is being further developed and used at
École nationale de l'aviation civile (ENAC),
[3] a
French civil aeronautics academy. Several vendors are currently producing Paparazzi autopilots and accessories.
Overview
An autopilot allows a remotely piloted aircraft to be flown out of sight.
[1] All hardware and software is
open-source and freely available to anyone under the
GNU licensing agreement. Open Source autopilots provide flexible software: users can easily modify the autopilot based on their own special requirements, such as forest fire evaluation.

Paparazzi collaborators share ideas and information using the same
MediaWiki software that is used by
Wikipedia .
[6]
Paparazzi accepts commands and sensor data, and adjusts flight controls accordingly. For example, a command might be to climb at a certain rate, and paparazzi will adjust power and/or control surfaces. As of 2010 paparazzi did not have a good speed hold and changing function, because no air
speed sensor reading is considered by the controller.
[5]
Delft University of Technology released its Lisa/S chip project in 2013 which is based on Paparazzi.

Mechanisms
Hardware
Paparazzi supports for multiple hardware designs, including
STM32 and
LPC2100 series
microcontrollers . A number of
CAD files have been released.
Paparazzi provides for a minimum set of flight sensors:
[8]
Attitude (orientation about center of mass) estimation is done with a set of infrared
thermopiles .
Position and altitude are obtained from a standard
GPS receiver.
Roll rate measurement may be input from an optional gyroscope.
Acceleration from optional inertial sensors.
Direction from optional magnetic sensors.
Software
The open-source software suite "contains everything" to let "airborne system fly reliably".
