Global Positioning System, also known as GPS, is a satellite-based global positioning system that determines coordinates and time data at any point of the globe and orbit within one nanosecond with an accuracy of ten meters.
The system has at least 24 satellites located in six orbits at an altitude of about 20,000 km and ground control center monitoring stations located in different parts of the Earth. These satellites constantly emit encoded radio signal indicating their current position and the exact time. From the propagation delays of this signal, a special GPS receiver can calculate the position and velocity.

GPS was originally planned as a military project. The first test satellite was launched into orbit on 14 July 1974, and the first operational satellites of the future system was put on service on 22 February 1978. From 1978 to 1980, the number of satellites reached six. On 6 January 1980, the system was placed in operation for the first time. The last of the 24 satellites required for the full coverage of the globe was launched into orbit in late 1993, the and the system went on full alert 17 January 1994.
In 1983, due to a navigation error a South Korean civilian airliner with 269 people on board entered Soviet airspace and was shot down by a Russian fighter. Given the tragedy that could have been avoided, the U.S. president authorizes the use of the system for civilian purposes.
Students who are about to write a research paper on Global Positioning System have to imagine the importance of this endeavor. The significance this system presents for a number of the most important areas of human activity requires the author to take the study seriously and to provide a full account of the system predecessors, the history of its development, the basic principles of its organization and operation. It is also important to show in what fields the system has found its application, and to indicate what value the system presents for the modern man.
To write correctly a college research paper on Global Positioning System, students have to consider carefully all the facts and present them as accurate as possible in their paper. Many beginners find it difficult to compose the first opus properly, because it is not enough to find a topic of interest and disclose it.
In relation to the research proposal writing, the principles are entirely different. For better understanding, students should use free example research projects on different Global Positioning System topics. After reading some of them, they will understand how to write high-quality scientific text, to keep the main line of the narrative, to outline clear structure of the text. Free sample research projects will help you feel more confident, and that is half the battle.
