Earth observation is diversifying, and now includes new types of systems, such as citizen observatories, unmanned aerial vehicles and wireless sensor networks. However, the Copernicus Programme vision of a seamless chain from satellite data to usable information in the hands of decision makers is still largely unrealized, and remote sensing science lacks a conceptual framework to explain why. T...

ESA’s Proba micro-satellite, launched on October 22, 2001, is in an elliptical 600 km LEO Sun-synchronous orbit. Principally meant for the in-orbit evaluation of new spacecraft technologies and satellite operational autonomy, Proba is also being employed as a flight opportunity for a range of Space Environment and Earth Observation instruments, to take advantage of the pointing and agility capa...

Satellite wind scatterometers are microwave radar instruments desimted s~ecificallv to . . measure near-surface wind speed and direction over the global ocean. NASA has a long term commitment to ocean wind remote sensing, starting from Seasat-A Satellite Scatterometer (SASS), through NASA Scatterometer (NSCAT), to SeaWinds-1. SASSwas launched in June, 1978 and operated for three months. NSCAT w...

This paper presents a simulated design of an envisioned future intelligent Earth observing satellite system (FIEOS). The proposed system is a space-based architecture for dynamic and comprehensive on-board integration of Earth observing sensors, data processors and communication systems. It is intended to enable simultaneous, global measurements and timely analyses of Earth’s environment for a ...

We consider the problem of downloading observations for a next-generation agile Earth-observing satellite. The goal is to schedule file downloads during ground reception station visibility windows while minimizing information age and promoting the fair sharing of the satellite between users. It is a complex scheduling problem with constraints ranging from unsharable resources to timedependent p...
