In this book, the authors present new satellite development research. Topics discussed include satellite-linked GPS collars deployed on elephants in Tsavo ecosystems in Kenya; enhancing resiliency of broadband satellite communication emergency networks through propagation impairment mitigation techniques; satellite applications for very short range weather forecasting systems in Southern African developing countries; eliminating ionospheric effects in multifrequency global navigation satellite systems; attitude control systems for arc-second stabilization of 30-kg micro astronomy satellites; and third generation GPS systems.
