An operational method using ARGOS orbital elements for navigation of AVHRR imagery

Abstract

This paper presents a method for navigating AVHRR images in realtime without resetting to ground control points. The satellite orbital elements used for the orbit extrapolation are calculated by the ARGOS Data Collection and Location System. The method has been tested by ground control point location on ten NOAA-9 AVHRR images and gives satisfactory results; the positioning error varies from 1-6 to 10-4km with a mean value of 4-7km.
