Abstract
(DE) Es ist ein Luftfahrzeug (100) mit einem Missionscomputer (110), einem GNSS-Empfänger (120) mit einer ersten Luftschnittstelle und einem ersten Receiver und einer Datenübertragungseinheit (130) mit einer zweiten Luftschnittstelle und einem zweiten Receiver, wobei die Datenübertragungseinheit ausgestaltet ist, Daten über einen verschlüsselten, bidirektionalen Kommunikationspfad zu empfangen, beschrieben. Der Missionscomputer bestimmt einen Positionswert für das Luftfahrzeug basierend auf von dem GNSS-Empfänger empfangenen Satellitensignalen, auf welche ein Korrekturterm angewandt wurde, welcher dem Luftfahrzeug über die Datenübertragungseinheit übermittelt wird, um korrigierte Satellitensignale zu ermitteln. Die korrigierten Satellitensignale dienen als Basis für das Ermitteln eines korrigierten Positionswertes Der Missionscomputer greift auf einen GNSS-Empfänger und eine Datenübertragungseinheit zurück, welche Bestandteil des Luftfahrzeugs sind, so dass zum Ermitteln der korrigierten Satellitensignale keine gesonderte Hardware-Baugruppe erforderlich ist. Daneben ist eine Bodenanordnung mit einer zugehörigen Bodenstation und optional mit einer Prüfeinheit zum Überprüfen der korrekten Bestimmung des korrigierten Positionswertes beschrieben.
(EN) The invention relates to an aircraft (100) having a mission computer (110), a GNSS receiver unit (120) with a first air interface and a first receiver and a data transmission unit (130) with a second air interface and a second receiver, the data transmission unit being designed to receive data via an encrypted, bidirectional communication path. The mission computer determines a position value for the aircraft on the basis of satellite signals received by the GNSS receiver unit, to which satellite signals a correction term has been applied, which is transmitted to the aircraft via the data transmission unit in order to define corrected satellite signals. The corrected satellite signals act as a basis for defining a corrected position value. The mission computer has recourse to a GNSS receiver unit and a data transmission unit, which are part of the aircraft, so that a separate hardware assembly is not needed to define the corrected satellite signals. The invention also relates to a ground arrangement with an associated ground station and optionally with a testing unit to check the correct determination of the corrected position value.
(FR) L'invention concerne un aéronef (100) comportant un calculateur de mission (110), une unité réceptrice de GNSS (120) dotée d'une première interface radio et d'un premier récepteur et une unité de transmission de données (130) dotée d'une seconde interface radio et d'un second récepteur, l'unité de transmission de données étant conçue pour recevoir des données par l'intermédiaire d'un trajet de communication bidirectionnel chiffré. Le calculateur de mission détermine une valeur de position de l'aéronef en fonction de signaux de satellites reçus par l'unité réceptrice de GNSS, auxquels signaux de satellites a été appliqué un terme de correction, lequel est transmis à l'aéronef via l'unité de transmission de données pour définir des signaux de satellites corrigés. Les signaux de satellites corrigés agissent en tant que base pour définir une valeur de position corrigée. Le calculateur de mission a recours à une unité réceptrice de GNSS et à une unité de transmission de données, qui font partie de l'aéronef, ce qui évite d'avoir besoin d'un ensemble matériel séparé pour définir les signaux de satellites corrigés. L'invention concerne également un dispositif terrestre doté d'une station terrestre associée et, éventuellement, d'une unité de test permettant de vérifier la détermination correcte de la valeur de position corrigée.
