Whatever the mission‚ be it manned or unmanned‚ for scientific research‚ applications or space transportation‚ a spacecraft must withstand the extreme stresses which occur during the launch phase‚ and once in orbit‚ the rigours of the space environment. There is one way of making sure of this: to test the spacecraft on Earth under conditions simulating‚ as closely as possible‚ those it will meet during the launch and its orbital life. This can be done with with tests which demonstrate by application

of satellite communication systems have been proposed using geosynchronous (GEO) satellites‚ as well as low earth orbit (LEO) constellations operating in the Ka-band and above. At these frequencies satellite networks are able to provide broadband services requiring wider bandwidth than the current services at C or Ku-band. As a consequence‚ some of the new services gaining momentum include mobile services‚ private intranets and high data rate internet access carried over integrated satellite-fiber

The current headlines regarding “extreme weather events” occurring around the world and here in America left a curiosity about the history and technology used to forecast the Earth’s weather. Around the world meteorologists use technology such as satellites‚ infrared‚ radio‚ and radar transmissions‚ to help determine the most accurate forecast possible. However‚ even with the most advanced technology available‚ no predication is 100% accurate. Captain Robert Fitzroy of Great Britain started a forecasting

How do cable and satellite TV signals get to my television? Cable TV: Cable TV companies lay wiring throughout the areas they service‚ including amplifiers to make sure signal strength is good throughout. Cable can then be easily brought into your home and connected to a cable box or directly into your TV. Satellite TV: Satellite TV companies send their signal to a satellite in space‚ which then sends it down to the dish on your roof. The dish then needs to connect to a receiver box‚ which connects

Wireless Power Transmission for Solar Power Satellite (SPS) (Second Draft by N. Shinohara) 1. Theoretical Background It is known that electromagnetic energy also associated with the propagation of the electromagnetic waves. We can use theoretically all electromagnetic waves for a wireless power transmission (WPT). The difference between the WPT and communication systems is only efficiency. The Maxwell’s Equations indicate that the electromagnetic field and its power diffuse to all directions. Although
