Common Elements Versus Unique Requirements in Various Types of Satellite Application Systems,have many elements in common. In fact very similar power systems, spacecraft platforms, stabilization and positioning systems, and tracking, telemetry, and command systems are used for the various types of application satellites. It is the payloads that tend to be quite specialized. Even in the fiel

Coping with the Hazards of Space Debris, orbits used for communications, remote sensing, and meteorological sensing and forecasting. The Chinese missile shootdown of the defunct Fengyun (FY-1C) weather satellite in 2007 and the collision of the Iridium and Cosmos satellites in 2009 have greatly heightened this concern. Increasingly sophis

Electromagnetic Radiation Principles and Concepts as Applied to Space Remote Sensing,undamental concepts of visible light in particular and of electromagnetic radiation in general. Both the wavelike nature of light (the speed of light being 300,000 km/s through free space) and its particle-like nature (as photons) are considered. We introduce its wave properties which explain the ph
