Earth observation satellites are used for everything from weather reporting to pollution monitoring. Specific issues for communicating with these type of satellites include: High speed communication links, Ground based satellite tracking
LEO / MEO satellite communication presents special challenges; because of the faster apparent motion of the satellites, accurate tracking is required without introducing overly complex tracking systems.
Broadband maritime satellite communication systems have become an indispensable part of the communication needs in commercial and military shipping. With the ever increasing size of ocean going vessels getting the
