Global Communication Science with NASA’s Aid
NASA has put up its head in the field of science, too. NASA has played a significant and a crucial role to develop the satellite TV transmission technology. However, the TV signals are only one type of data that is being transmitted by the satellites. Computer images, telephone signals and computer data’s are also transmitted throughout the world via the use of satellites.
There are a number of American countries who sell the satellite data-transmission service. This commercial system of space interaction advanced from the high-risk technology that was extended and tested by NASA in the years between 1960 and 1970. This string based technology offered the American telecommunication industries to follow the path in operating as well as building communication satellites.
The series of Application technology Satellites of NASA were developed between the years of 1966 and 1974. These satellites played an important role in stimulating the advancements in telecommunication technologies. These areas include solid state high power transmitters, Use of digital computers, Advanced materials like graphite composites to build the satellites, Geosynchronous orbit, that orbits with the earth to keep the satellite above a specific point on the ground always, Large antennae offering high quality signals to the small ground receivers.
Satellite stabilization- It keeps the satellite from wobbling in the orbit.
NASA initiated the use of the Geosynchronous orbit (GEO) satellites to be able to look down on Low Earth Orbit satellites (LEO). The Geo satellite transmits the information between the LEO satellites. The information is also conveyed from the LEO satellite via the GEO satellite and down to the ground. This technology simply indicates that the satellite companies along with NASA can activate their satellites using minimum ground stations.
NASA has installed six Tracking and Data Relay Satellites of its own. The Tracking and Data Relay Satellites is a network of the GEO satellites, which offers interaction and tracking services to the low earth orbiting spacecraft and the space shuttle. The highly developed satellite in the long run of NASA’s experimental communication satellites is the Advanced Communication Technology Satellite. It was launched in the year 1993, September. The Advanced Communication Technology Satellite acts as a switchboard in the sky. It is widely used by the universities, industries and the government to form new services of satellites that features real-time television transmission to airliners.
Now, the commercial companies are taking advantage of this novel technology. They are taking the lead in offering the satellite services to the public, in general. Nevertheless, with Advanced Communication Technology Satellite, NASDA has remained in the front and at the topmost position to develop data transmission as well as satellite technology.
This way, NASA has played a vital role and proved to be very effective in the field of science for global communications. It has offered a noteworthy contribution to develop the satellite TV transmission technology, which is now very important and significant for all people, in general.
