There is a detached type of substances which is named semiconductors. This class was discovered in early 1980's but there were no needed technologies to carry on the further researches. The research of semiconductors was continued just in the 1920's. In 1923 Russian scientists proved the ability of usage of semiconductor-metal contacts to quicken the producing of fluctuations. There was no possibility to create some sophisticated devices as semiconductor assembly. The most significant event in the history of semiconductor devices was the creation of the first transistor by Bell corporation in 1949. Since then many persons all over the world become interested in such kind of matter as semiconductors.

The interest to optical characteristics of semiconductors revived because of research of simulated emission in semiconductors. It caused the appearing of semiconductor laser system based on usage of p - n barriers and then on heterojunction.

NAVSTAR GPS is a very famous navigation system that is applied by a great number of people nowadays. This system is created for ascertaining the position and speed of the objects at any place on Earth. It can be done almost in any weather conditions and in all the territories on Earth including polar territory and in outer space to 100 kilometers above Earth. The developer of GPS became the United States Department of Defense that has accomplished this system.

The principle of the position detecting is in measuring the distance from the point with the definite coordinates to an object. The sending satellite spreads radio signal to a GPS antenna and the delay time is calculated to define the distance between the receiver and transmitter. 3-D coordinates may be defined when GPS receiver will know the distance to 3 satellites and the time of the NAVSTAR GPS system. And when we need to define coordinates and altitude of a receiver we are to apply minimum 4 signals from 4 transmitters. Orbital force supervision is realized from the main control station that is located in Schriever base, Colorado.

A great amount of usual people as well as the police, sailors and rescuers apply Global Positioning System for different needs, mostly for navigation, position and velocity detection. GPS systems are being sold in different shops and they are built in cell-phones, personal computers and onboarders. GPS receiver allows a consumer to detect geographical coordinates of the receiver's situation at the present moment of time. The exactness of the detection of the signal position is from 3 to 5 meters and it is really heightened with the correction radio signal from Earth and the calculating error is one millimeter.

Working together

Humans interact in three basic ways: conversations, transactions, and collaborations.
