    Communication satellites, used for relaying anything from telephone signals, radio, and television signals, have been orbiting Earth since the first in 1962. Currently, there are more than 1,100 publically and privately owned active communication satellites in orbit with more than 2,600 inactive ones causing a significant amount of space debris. Importantly, communication satellites provide our security and our entertainment. At a high altitude of nearly 36,000km from Earth, the geosynchronous orbit (GEO) is an ideal location for communication satellites that have a requirement to be over the same position of Earth. This “sweet spot” above Earth takes one full day to complete an orbit and is ideal for ground-based antennas that are stationary. Should the satellite be positioned at a zero degree incline, it would be in a geostationary orbit and lie on the equator.…

    launched a small sphere of aluminum-magnesium-titanium alloy into space. The Soviets called it Sputnik, which is a Russian word for “Fellow Traveler” (Regan, 2002). This would go down as what we now consider the birth of satellite technology. It was an important time in human history looking back. Sputnik sparked the space race into full swing. The main two countries that participated in the space race were the Soviet Union and the United States. Mainly due to the fact that they had the biggest…

    Cellular networks are a type of wireless WAN. Various technologies are utilized in cellular networks but there are only three basic modes of signal communications. These are simplex, half duplex and full duplex. In simplex transmissions the signal goes in only one direction and this type is usually seen in television and radio stations. Half duplex signaling is bi-directional but each signal has to wait its turn because only one can travel at a time. Examples of half duplex are the…

    The design for a satellite to photograph the surface of the earth requires a list of desired features, prioritized from most to least importance, and balanced against the physics of nature’s various waves. To photograph natural and man-made objects on the earth’s surface, the camera must be in the proper location, contain ample power to operate all systems, contain sufficient image resolution to capture the target area, and have the ability to transmit the digital images quickly and reliably to…

    while in orbit; unfortunately the satellite failed to ignite on its fourth stage in its launch process and never made it to orbit. During the time of Explorer 2, the Soviets were also at work with Luna 2, this probe became the first to hit the moon but after 33.5 hours into flight the signals were dead. The US then created another satellite, the fourth satellite by America, and the first satellite to be solar-powered. They created the Vanguard 1, the first part of the Vanguard Project. Although…

    drop something out into space. In the text,”Space Junk” it says,”On March 11, 2001, astronaut James Voss had dropped a large vise while on a space walk.” Second, some space debris are satellites that are not in use. Many people launch these satellites for communications, television transmission, research, and spying, but some satellites aren't useful because the satellites don't work forever. Debris out in space is man made things and also natural, but we should try at least getting the man made…

    Sir Julian Corbett’s Thoughts on U.S. Hegemony of Low Earth Orbit Satellites – manmade systems deliberately placed in Earth’s orbit – undeniably benefit humankind, from enhancing scientific understanding, communications, and situational awareness to expanding commerce and development. Correspondingly, low-Earth orbit (LEO) represents the point of entry for the security, economic, and informational benefits humans derive from space because almost every manmade object traveling through this…
