The Development of Semiconductor Inventions

Semiconductors are considered to be a special kind of chemical elements. People got known about these substances in the end of the 19th century, but just in the 20th century scientists managed to obtain more knowledge about them. In 1923 Russian scientists proved the ability of usage of semiconductor-metal contacts to accelerate the producing of fluctuations. But such parts as igct that are used today were invented considerably later. Only in the beginning of the 60's with the appearing of transistors in 1949 the broad use of crystal detectors started. The intensive research of the features of semiconductors was started at the same time.

Stimulated emission is actually a very interesting feature of semiconductors that has been researched for several tens of years. It led to the creation of semiconductor laser device based on utilizing of p - n barriers and then on heterojunction.

Some Words about Global Positioning System of the XXI century

Global Positioning System is a very famous navigation system that is used by a great number of people today. The aim of the system is the detecting of the velocity and situation of the objects. It may define the object at any area on Earth, even in polar areas and in space to 100 kilometers above Earth in any weather conditions. GPS was worked out and realized by the United States Department of Defense.

The basic principle of functioning is definition of the position by the method of measuring the distance to an object from the point with fixed coordinates. The distance is counted by the delay time of the signal spreading from the sending satellite to the receiving of it by a GPS antenna. It signifies that to detect 3-D coordinates GPS receiver must identify the distance to 3 satellites and the time of the GPS system. And to detect a receiver's coordinates and altitude it has to use minimum 4 satellites' signals. The direction of the satellites from Earth is realized in the control station that is located in Schriever base, Colorado.

A lot of usual people as well as the police, sailors and rescuers apply GPS systems for different needs, mostly for navigation, position and speed detection. If you need handheld GPS systems you may buy it almost everywhere today. It is also built in the most personal computers, cellular phones and onboarders. GPS receiver gives you a possibility to define geographical coordinates of the receiver's position at the present moment of time. The maximum accuracy is from three to five meters and with the correction signal from Earth it is to 1 millimeter.
