Abstract
Recent developments in small-satellite technology open up new possibilities for Earth observation. We expect that in the next decade large CubeSat constellations will arise with hundred, up to thousand satellites in low Earth orbit. While most constellations will be dedicated to internet of things and global communication, a larger number of satellites might be also equipped with rather low-cost sensors – suited for monitoring of the Earth’s atmosphere. In this context, the GNSS radio occultation (RO) technique has been identified as a promising tool for remote sensing of the atmospheric state. For processing of the RO signals, a new analysis method has been developed, which is based on tomographic principles.
In this presentation, we will highlight the basic principles of the developed approach and will show a series of closed-loop validations to demonstrate the potential of tomographic techniques for analysis of dense CubeSat constellations. Applied to GNSS signal delays it will allow for a detailed reconstruction of the water vapour distribution inside and outside convective systems and therefore, will contribute to a better understanding of convective storms, heavy precipitation and related weather events.
