On one hand it is important to gather knowledge about the observation geometry during the flight and on the other hand it is necessary to acquire as much information as possible about the object space which is to be mapped. This paper will concentrate on the acquisition of information about the observation geometry. With the advent of the Global Positioning System (GPS) the real-time determination of an aircrafts position with high accuracy (« 1m) has become available. Besides positioning, new developments of multi-antennae GPS receiver opened up the opportunity to measure also the aircrafts attitude, with an accuracy of less than 0.5 degrees in real-time. Hence, with GPS it has become possible to determine the entire exterior orientation of a moving aircraft in real time with high precision. The concern of this paper is to present an accuracy analysis of GPS positioning and attitude determination under real-time mapping conditions. This analysis is based on experimental airborne GPS data for a typical photogrammetric application. KURZFASSUNG Grundsätzlich werden zur Herstellung von Karten aus Bildinformation, in Echtzeit, zwei wesentliche Informationsquellen benötigt. Neben semantischer Information über die Objekte des Beobachtungsraumes, spielt die Beobachtungsgeometrie zum Zeitpunkt der Aufnahme eine zentrale Rolle. Die direkte Bestimmung der Beobachtungsgeometrie in Echtzeit ist die maßgebliche Fragestellung die in dieser Arbeit behandelt werden soll. Mit der Entwicklung des NAVSTAR/Global Positioning System bietet sich nun erstmals die Möglichkeit die Parameter der äußeren Orientierung direkt mit hoher Genauigkeit (< 1m) zu bestimmen. Neben der Positionierung, kann die Neigung eines Flugzeuges durch die Nutzung von Multi-Antennen GPS Empfängern ebenfalls direkt in Echtzeit mit Genauigkeiten im Bereich von einigen Zehntel Gon bestimmt werden. In dieser Arbeit wird eine Genauigkeitsanalyse der GPS Positionierung und Neigungsbestimmung unter den Rahmenbedingung einer Echtzeit-Kartierung diskutiert. Die Analyse basiert auf experimentellen Flugdaten einer photogrammetrischen Befliegung. 183
