Global Positioning System (GPS): The Global Positioning System (GPS) is a space-based satellite navigation system that provides location and time information in all weather‚ anywhere on or near the Earth‚ where there is an unobstructed line of sight to four or more GPS satellites. It is maintained by the United States government and is freely accessible to anyone with a GPS receiver. The GPS program provides critical capabilities to military‚ civil and commercial users around the world. In

Application of satellite remote sensing technology effectively harnessing the natural resource potential is the prime objective of present day’s remote sensing programmes. The space-based sensors are utilized to provide a wide range of information available in the electromagnetic tapes‚ in a synoptic or more frequent manner for sustainable development and utilization of natural resources. In India‚ though this technology has taken its birth from late sixties using Hassle blad camera as the source

Comparing and Contrasting There are two forms of radio‚ AM/FM and satellite. Also known as analog and digital‚ both methods of broadcasting are transmitted into a radio system‚ or stereo‚ built with a receiver. Information received into the system is then translated into sound. The sound that is then heard is a song‚ an advertisement‚ or a radio talk show. Both AM/FM and satellite radio produce the same product‚ sound that is listened to. AM/FM stations are transmitted and received through

plane is from the satellite. To ensure the accuracy of timing‚ each GPS satellite carries four atomic clocks. The GPS is comprised of three components: the space segment‚ the control segment‚ and the user segments. The space component consists of approximately 31 satellites. At any given moment‚ a minimum of twenty-four satellites are operational in an orbit‚ ensuring that at least four satellites are in view at the same time from a point on the Earth. With four satellites‚ the altitude of

How many labor hours should the eighth satellite require? 100‚000 labor hours x.512 = 512‚000 labor hours for the 8th satellites A. How many labor hours for the whole project of eight satellites? 100‚000 labor hours for per unit x 5.346 = 534‚600 total labor hours for the whole project of 8 satellites B. What should NSCD estimate as the total cost for this project? 534‚600 labor hours x NOK 300 = 160‚380‚000 NOK 12‚000‚000 R&D + NOK 6‚000‚000 = 18‚000‚000 160‚380‚000

describing GPS - A navigational system involving satellites and computers that can determine the latitude and longitude of a receiver on Earth by computing the time difference for signals from different satellites to reach the receiver. Today‚ it is widely used by the civilian public for both commercial and recreational use. In addition to GPS‚ other systems are in use or under development. The Russian Global Navigation Satellite System (GLONASS) was in use by only the Russian

A satellite that revolves in the same direction as the earth rotates is said to be in a posigrade. 3. The geometric shape of a noncircular orbit is a ellipse. 4. The center of gravity of the earth is called the geocenter. 5. The time for one orbit is called the period. 6. The angle of inclination of a satellite is 0 degrees if it orbits over the equator
