Abstract
Description
Les microdrones assimilables à l'aéromodélisme, sont pilotés à vue . LeThe microdrones comparable to the model aircraft, are piloted by sight. The
pilote qui se trouve au sol a en principe suffisamment d'informations visuelles pour manoeuvrer l'aéronef. Cependant, au-delà de 300 mètres, le guidage devient très difficile et aléatoire : il devient difficile, voire impossible de faire survoler un objectif précis à l'aéronef car la perception binoculaire du pilote est imprécise voire absente. Cela peut engendrer une erreur importante, de l'ordre d'une centaine de mètres par rapport à la position de survol souhaitée. pilot on the ground has in principle sufficient visual information to maneuver the aircraft. However, beyond 300 meters, the guidance becomes very difficult and random: it becomes difficult or impossible to fly over a specific objective to the aircraft because the binocular perception of the pilot is inaccurate or absent. This can cause a significant error, of the order of a hundred meters compared to the desired overflight position.
Pour les aéronefs sans pilote plus importants, à grand rayon d'action, tels que les minidrones, le pilotage s'effectue hors portée de vue. Le guidage est effectué le plus souvent au moyen d'un retour d'image vidéo issue d'une caméra embarquée à bord de l'aéronef. Le risque de voir l'aéronef se perdre est quasiment certain. Même si avant d'effectuer une mission, une étude approfondie de la zone géographique à survoler a été réalisée. La désorientation est toujours à craindre, d'autant que le pilote au sol ne ressent pas les inclinaisons de l'aéronef. Il n'est pas rare qu'un véritable pilote de petit monomoteur se perde s'il ne suit pas en temps réel la progression de son aéronef sur une carte. For larger unmanned aircraft with a large radius of action, such as minidrones, flying is beyond sight. The guidance is most often performed by means of a video image return from a camera on board the aircraft. The risk of seeing the aircraft get lost is almost certain. Even if before carrying out a mission, an in-depth study of the geographical area to fly over was carried out. Disorientation is still to be feared, especially as the pilot on the ground does not feel the inclinations of the aircraft. It is not uncommon for a true small-engined pilot to be lost if he does not follow the progress of his aircraft on a map in real time.
Il existe différents dispositifs qui utilisent des modules télémétriques orientés vers le sol, des liaisons par satellite, des ondes ultrasonore, ou encore des procédés à visée laser. Leur mise en oeuvre est complexe et onéreuse. De plus, la précision obtenue peut varier en fonction des condition extérieures. There are various devices that use ground-oriented telemetry modules, satellite links, ultrasonic waves, or laser targeting methods. Their implementation is complex and expensive. In addition, the accuracy obtained may vary depending on the external conditions.
Considérant ces difficultés, l'invention a été conçue pour être d'une mise en oeuvre simple, et d'un coût peu élevé. Elle permet d'équiper entre autres, et avec une bonne sécurité les minidrones de reconnaissance ou d'observation. Considering these difficulties, the invention was designed to be of simple implementation, and low cost. It allows to equip among others, and with a good security the minidrones of recognition or observation.
Le présent dispositif a pour objectif de faciliter le guidage du minidrone. Pour cela des informations sonores ou visuelles sont envoyées de l'aéronef vers le pilote au sol lui offrant ainsi la possibilité de positionner l'aéronef sur la cible à observer et également l'aider à revenir vers sa base. Le dispositif donne en temps réel au pilote la distance à vol d'oiseau qui le sépare du minidrone. Cette information de distance est capitale pour ne pas risquer de dépasser une limite rendue indépassable en raison de la valeur des puissances d'émissions HF des divers organes de contrôle. Un tel dépassement entraînerait la perte de contrôle de l'aéronef consécutive ou additive d'une perte de réception vidéo. The present device aims to facilitate the guidance of the minidrone. For this, sound or visual information is sent from the aircraft to the pilot on the ground thus providing him the opportunity to position the aircraft on the target to observe and also help him back to his base. The device gives the pilot in real time the distance as the crow flies separates him from the minidrone. This distance information is essential not to risk exceeding a limit made unsurpassable because of the value of the HF emissions power of the various control bodies. Such an overshoot would result in the loss of control of the consecutive or additive aircraft from a loss of video reception.
Selon l'invention, le principe utilisé est d'informer le pilote par des ordres simples. Ces ordres peuvent être du type 90 droite/gauche ou demi-tour . Un affinage est rendu possible par des ordres gauche/droite en vue de positionner l'aéronef sur une zone choisie. La technique utilise l'incorporation d'un système de localisation par satellite de type GPS ou équivalent à bord de l'aéronef. Ce système envoie des informations de positions au moyen 45 50 1 d'une liaison HF. Un deuxième système de type GPS ou équivalent, est incorporé à une centrale technique située au sol près du pilote. Cette centrale reçoit les coordonnées issues du GPS ainsi que l'altitude du minidrone. Elle calcule la position de l'appareil par rapport au 2ne système GPS dont la centrale est équipée et agit en conséquence. According to the invention, the principle used is to inform the pilot by simple orders. These orders can be of type 90 right / left or half-turn. Refinement is made possible by left / right commands to position the aircraft on a selected area. The technique uses the incorporation of a GPS or equivalent satellite location system on board the aircraft. This system sends position information by means of an HF link. A second GPS-type system or equivalent, is incorporated in a technical center located on the ground near the pilot. This station receives the coordinates from the GPS and the altitude of the minidrone. It calculates the position of the device in relation to the 2nd GPS system whose control unit is equipped and acts accordingly.
Les coordonnées en X et Y (figure 1) sont données par le différentiel des coordonnées du GPS de l'aéronef et des coordonnées du GPS de la centrale au sol. L'orientation Sud-Nord et Est-Ouest est donnée par le signe positif ou négatif du différentiel. Le calcul, présenté sur la figure 1 donne l'angle ( 3). La centrale au sol est équipée d'une boussole électronique qui indique le Nord. The coordinates in X and Y (FIG. 1) are given by the differential of the GPS coordinates of the aircraft and the GPS coordinates of the ground station. The South-North and East-West orientation is given by the positive or negative sign of the differential. The calculation, shown in Figure 1 gives the angle (3). The ground station is equipped with an electronic compass that indicates the North.
La figure 2 montre le principe de calcul de la distance entre l'aéronef en vol et la centrale au sol. Ce calcul permet d'obtenir également l'angle (c)) qui permet l'orientation selon la coordonnée Z d'une l'antenne de réception ou d'émission. Le calculateur de bord de la base dispose de toutes les données nécessaires permettant de guider le pilote afin qu'il positionne l'aéronef vers une position GPS définie. 2q 25 2 Figure 2 shows the principle of calculating the distance between the aircraft in flight and the ground station. This calculation also makes it possible to obtain the angle (c) which allows the orientation according to the Z coordinate of a receiving or transmitting antenna. The base computer of the base has all the necessary data to guide the pilot to position the aircraft to a defined GPS position. 2q 25 2
