The role of the atmosphere in geodetic remote sensing

Abstract

Geodetic remote sensing signals inherently contain information about the medium they must pass through, namely the Earth's atmosphere. The information added to such a signal can take the form of unwanted noise, or can be useful, depending on the nature of the observing system. This study focuses on two contrasting approaches to atmospheric interaction with geodetic satellite signals, atmospheric noise reduction in Interferometric Synthetic Aperture Radar (InSAR), and meteorological data acquisition over the ocean using the global positioning system (GPS).
