<GPS; Global Positioning System>
GPS, a Global Positioning System is a network of orbiting satellites that send precise details of their position in space back to earth. The signals are obtained by GPS receivers, such as navigation devices and are used to calculate the exact position, speed and time at the vehicles location. The first GPS system was developed in 1960s for US Navy to navigate ships more fast and accurately. Nowadays, global positioning system is built in most of the phones and navigators to give drivers their location to navigate roadways. The technology is now developed enough to tell drivers to avoid the traffic or tolls. The initial purpose of the invention of GPS was for the military to has accurate data, but it is interesting that today the system is widely used for people to catch their Pokemon with their phone.
<Relations to Computer Science>
GPS is used in guiding and mapping applications and used in location services. These days, GPS not only provides the position but is also used in various applications in computer science such as wireless video processing, monitoring using mobile and localization of automobiles. GPS receivers take information that is transmitted from the satellites and uses triangulation to calculate a user's location. In order for GPS to calculate data and communicate between devices, it needs an algorithm to manage the signal in between them. In order to execute this, certain rules need to be followed to analyze statistical data that were collected. Matlab and Python are widely used to program this system.
