This paper presents a systems architecture methodology that has been developed to analyse architectures for Low Earth Orbit (LEO) commercial satellite data relay systems, here named as Earth Orbiting Support Systems (EOSS). LEO relay constellations are crucial to provide affordable services to a whole range of missions for which traditional GEO data relay is not an option, due to antenna size o...

Biography Peter Teunissen is professor of Geodesy and Earth Observation and Federation Fellow of the Australian Research Council. Nanthi Nadarajah is postdoc research fellow at the GNSS Research Centre of Curtin University, Perth, while Gabriele Giorgi and Peter Buist are both PhD candidates at the Mathematical Geodesy and Positioning (MGP) section of the Delft University of Technology. Their r...

The Earth Observation Center (EOC) of DLR realizes processors for ALOS and EnMAP high-resolution optical remote sensing satellite missions. The functional and developmental similarities and differences of the DLR processors are analyzed. It turns out that despite or precisely because of pan-chromatic and multispectral versus hyperspectral imaging as well as the postversus pre-launch establishme...

The atmosphere of the Earth is opaque to most wavelengths of light in the infrared, in the ultraviolet and in the X-rays. Due to this fact observation of celestial objects in X-rays (in the range of energies from 0.5 to 20 keV) must be carried out outside the atmosphere at altitudes greater than 100 kilometers, namely from space. The development of X-ray astronomy had therefore to await the dev...

Earth observation data and related services from the Copernicus Program are meanwhile embedded in the European spatial data infrastructures. From land, marine and atmosphere monitoring to emergency management and support to humanitarian action, the rich service portfolio provides satellite-based information products for Europe and – for some applications – even globally. This AGIT Special addre...

The ESA Sentinels constitute the first series of operational satellites responding to the Earth Observation needs of the EU-ESA Global Monitoring for Environment and Security (GMES) programme. The GMES space component relies on existing and planned space assets as well as on new complementary developments by ESA. This paper describes the Sentinel-1 mission, an imaging synthetic aperture radar (...

This paper aims at the rescheduling of observing spacecraft imaging plan under uncertainty using ant colony algorithm. First, this paper provides a brief analysis about the uncertainties in spacecraft observation scheduling. And then, this paper establishes the mathematical model and manages to solve the rescheduling problem by ant colony algorithm. Finally, the above method is applied to solve...

SatStat – Satellite derived Statistical data on forest-change area – project is being developed under the framework of the European Space Agency (ESA) Announce of Opportunities (AO) for Portugal. The goals of this AO are the promotion of Earth Observation (EO) data usage and the contribution to the development of applications for Global Monitoring of Environment and Security (GMES). SatStat acc...
