Title
(DE) Präzisionsanflug- und Landesystem für Luftfahrzeuge
Abstract
(DE)

Es ist ein Luftfahrzeug (100) mit einem Missionscomputer (110), einem GNSS-Empfänger (120) und einer Kommunikationsschnittstelle (130), welche 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 Kommunikationsschnittstelle 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 Kommunikationsschnittstelle 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.
