Paparazzi in the News

  • UAVs in wind parks - September 16, 2010
    Paparazzi measures wind vectors/turbulences around wind turbines for a more efficient planning of wind parks. The goal is to reduce the impact that a turbine causes to the ones downstream. TV coverage in Swiss-German.

  • Flight International: COTS UAV makes arctic debut - April 3, 2008
    A Norwegian university has flown an autonomous unmanned air vehicle equipped with meteorological sensors over the Spitzbergen/Svalbard island in the arctic circle in temperatures of -20 degrees C (-4 degrees F), winds up to 15m/s (50ft/s) and at an altitude of 4,900ft (1,500m). The Multiplex Funjet UAV was modified with electronics for open-source Paparazzi autopilot software…

  • SPIEGEL Online: Projekt "Paparazzi": Bau dir deinen fliegenden Spion - December 28, 2007
    Unbemannte Mini-Flugzeuge werden derzeit vor allem von Militärs genutzt. Doch eine Drohne, die selbständig vorgegebene Routen abfliegt, lässt sich auch selbst bauen. Für etwa 1000 Euro bekommt man ein Flugzeug, das sich bequem per Software dirigieren lässt.
    Der Flieger macht nicht, was er soll: Plötzlich dreht er um 180 Grad und kehrt zum Startpunkt zurück. "Alles ist unter Kontrolle", sagt Antoine Drouin und die Zuhörer auf dem Chaos Communication Congress in Berlin lachen…

  • golem.de: 24C3: Paparazzi - Open-Source-Autopilot für Modellflugzeuge - December 28, 2007
    Demo von Flugplanänderungen zweier autonomer Modellflieger über Netzwerke
    Auf dem derzeit in Berlin stattfindenden 24. Chaos Communication Congress (24C3) zeigten Martin Müller und Antoine Drouin von der Ecole Nationale de l'Aviation Civile (ENAC) vor versammeltem Hacker-Publikum wie ein wenig kostenintensiver GPS-basierter Autopilot aussieht. Mit der ebenfalls dafür entwickelten Software lassen sich mit einem Netzwerk sogar mehrere Flugzeuge an verschiedenen Standorten verwalten…

  • HACK A DAY: 24C3 Build your own UAV - December 27, 2007
    The 24th annual Chaos Communications Congress in Berlin is already off to a great start. The first talk we attended was [Antoine Drouin] and [Martin Müller] presenting Paparazzi - The Free Autopilot. Paparazzi is an open source hardware and software project for building autonomous unmanned aerial vehicles. The main hardware board has an ARM processor and GPS. It uses inertial and infrared sensors to determine orientation and altitude. The four infrared thermopiles measure the air temperature. The ground is warmer than the sky and if you compare the temperature in the direction of each wing tip your can tell what angle the airplane is at. It's really that simple…

  • Elector Electronics: "Flying Robots" - Feb 2007
    As processors become ever more powerful we are witnessing the rise of more ’intelligent’ systems. We now look to sophisticated robots to assist or even replace us in difficult or hazardous environments. This is particularly true of military hardware where we have seen on our TV screens the use of unmanned aircraft and vehicles in some recent conflicts. The basic idea however is not so new; we take a look into the world of ‘drones’…
  • MAV Student Competition - Nov/Dec 2006
    The Air Force Research Laboratory Munitions Directorate and AUVSI’s Emerald Coast Chapter hosted the 2nd US-European Competition & Workshop on Micro Air Vehicles, MAV06, Oct. 29-Nov. 2. See page 23.
  • "Flight International: Dragon Slayer" - November 3, 2006
    The US Army battle laboratory is to buy several prototypes of the Miraterre Flight Systems Dragon Slayer hand-launched micro unmanned air vehicle (UAV) to develop it into a low-cost, expendable surveillance tool for soldiers...
  • Compétition internationale d'avions espions miniatures: Un succès qui suscite un intérêt international - (cached)- October 5, 2005
    5 octobre 2005 – Une équipe de cinq étudiants en génie de l'Université de Sherbrooke est arrivée première dans 4 catégories et 7e au cumulatif lors d'une importante compétition internationale d'avions espions miniatures, à Garmish-Partenkirchen, en Allemagne.
    L'événement nommé US-European Micro-Aerial Vehicle Technology Demonstration and Assessment a accueilli du 19 au 22 septembre 17 équipes provenant de partout à travers le monde. Chacune devait présenter un petit véhicule conçu par les membres et capable d'effectuer de la surveillance aérienne durant 30 minutes afin de détecter un terroriste dans un rayon de 500 m...
  • Flight International: "French School To Go It Alone" - (cached) October 4, 2005
    French national civil aviation school ENAC plans to demonstrate autonomous formation flight with two micro air vehicles in November. Two 1.4m (4.6ft)-wingspan, electrically powered Twin Star model aircraft are being fitted with GPS receivers and radio transmitters for the tests, in which they will fly about 10m apart, one following the other...
  • Flight International: "Teams chase MAV prize" - (cached) - September 27, 2005
    Open-source software, the foam-like material Depron and tiny infrared attitude controllers were common design elements among the 16 teams competing at the first US-European Micro Aerial Vehicle (MAV) Technology Demonstration and Assessment event, held in Garmisch-Partenkirchen, Germany last week...
  • "Flight International: Down Sizing" - September 26, 2005
    As the first generation of micro-scale UAVs, exemplified by the remote-control Wasp, reaches the hands of military users, the US Army’s MAV competition in Garmisch-Partenkirchen provided a glimpse of the future. The winning University of Arizona team’s fixed-wing MAV transmitted video while flying autonomously via GPS waypoints using an open-source flight-control software package, called Paparazzi, originally developed by France’s national aviation school Enac.
  • "Flight International Blog: From Fallujah to Garmisch-Partenkirchen" - September, 2005
    Robots are often used in the media to instil fear with Frankenstein like stories of the scientist and corporation having gone to far with a humanoid machine destroying all before it. But on today's battlefield, and for this US Army sponsored event, and for the war of tomorrow the robots will, apparently, look more like model planes.
  • DER SPIEGEL: "Bierdeckel auf Spionageflug" - July, 19, 2004
    Doch es gab auch Erfolge. Im Wettbewerb "autonomes MAV" etwa heimsten die Franzosen Antoine Drouin und Pascal Brisset von der Ecole Nationale de l'Aviation Civile souverän den ersten Preis ein. Vor allem der blaue Deltaflügler des Teams, Gewicht 425 Gramm, überzeugte die Jury. Nach erfolgreichem Start aus der Hand schaltete der mit einem Heckpropeller ausgestattete Flieger auf Autopilot und klapperte in geringer Höhe problemlos vier zuvor einprogrammierte Wegpunkte auf dem Flugfeld ab.

    En fonctionnement normal le filtre de Kalman propose un meilleur fonctionnement que la régression linéaire.
    Dans le cas de conditions changeantes, sans panne, le filtre de Kalman s’adapte mieux que la régression linéaire.
    Par contre dans le cas d’une panne, le filtre de Kalman ne l’a détecte pas et provoque une dérive du drone.

Manuals

  • "User's Manual"
    (1.5M, pdf) - February 2008
    This document is a quick guide to use the Paparazzi system. It is divided into two parts. In the first part an extensive procedure, which can also be used as a check-list, is given to prepare a flight, to operate the UAV and to analyze the results. The procedure is described for a given flight plan and a pre-programmed and tuned aircraft. The second part gives a description of the different components and tools of the system.
