Global Positioning Systems Essay -- Term Papers Research Essays

Global Positioning SystemsThe possibilities for the future afforded to the human race by the technology created today is endless. However, one technology has already and volition continue to cargonen the way people travel somewhat the planet Global Positioning Systems (GPS). For travelers throughout history, figuring out where they were and where they were outlet was one of the oldest problems. Even in recent years, water travel and positioning was decisive to many activities but extremely cumbersome. However, in its need for a dead form of global positioning, the Department of Defense (DoD) created the most useful navigation ashes in history. The creation and production of the GPS system by Rockwell collins changed the way people travel today and will continue to change the way people travel in the future. Imagine driving to the market store while sitting in the back seat translation a book or landing a plane in zero visibleness conditions and not worrying about where th e runway is. The scenarios listed are potential due to the creation of the GPS system, which consists of a series of 24 satellites, numerous ground stations, individual receivers, and radio signals to locate the exact position of an object. The adjoin by which all these components interact to cater location information is honest in theory but complex in reality.The basis of the GPS system in locating a receiver is a technique called triangulation. In triangulation, a receiver measures the distance from itself anywhere on earth to apiece of three satellites in the GPS system. In order to triangulate, it jump measures the distance to the first satellite and recognizes that it must be placed on the surface of a sphere. The spheres center must thus be located a... ...roaming receivers use the transmitted time differentials for the satellites they are measuring to perform the calculations and therefore have the ability to determine positions more accurately.As the accuracy of GPS systems continues to increase, the possible uses for GPS units will continue to increase. The possibilities for GPS uses are endless and GPS units in the future will aid in determining locations, booster people navigate the seas and skies, help track people and vehicles, aid in mapping roads and seas, and provide atomic accuracy timing to the entire world. Once the accuracy of GPS systems devolve to such small distances as centimeters, automatic construction equipment will prove roads without needing time consuming manual measurements, cars will drive themselves to influence destinations, and planes will be able to land in zero visibility conditions.
