GPS – Satellite Communication

The most reliable system that we see day to day in our life was the Satellite System.GPS(GLobal Navigation Satellite System) was first introduced by United States during the late 80′s.Normally the GPS was composed of three different parts which can be analysed by the three dimensional views namely latitute,longitude and altitude with respect to the dimension of time.

It was considered to be one of the satellite communication technology where it act as a useful tool to track the mappings of countries, surveying the lands,scientific uses,surveillance etc.,even they are used to analyze the earthquakes and triggers out the cellular network protocols.Nowadays GPS can be easily accessed through the mobile phones through GPRS connections where the particular location can be easily found in the map and at several times GPS act as the informer for security purpose by locating the areas where terrorist hang out.

Though the idea was introduced during the late 18th century, it was first successfully tested during the year of 1967 in United States.The GPS system was technically based in the radio navigation system developed in 1940′s,this works on receiving and transmitting the radio signals adjusted to a particular radio frequency.

Commonly a GPS receiver will include a input that act as an antenna tuned to a respective frequency that was transmitted by the satellites.A receiver in the GPS was considered to be not greater than a few number of channels.The speed of the GPS will be normally much higher but at some times the atmospheric conditions may affect the efficiency of GPS.

ConstellationGPSThis was actually explained in the way such that all the GPS signals should pass through the earth’s atmosphere especially through the ionosphere, so when there will be change in drastic climates that would be more challenge for the GPS Signals.But the introduction of GPS have made our human lives more simple than what so ever.
