GPS Navigation: Up Close and Personal
GPS Navigation has now become the buzzword when it comes to travelling guides. The GPS in GPS Navigation stands for the Global Positioning System, which is to date, the only functional Global Navigation Satellite System in the world. As travelling guides, GPS Navigation Systems are accurate, fast and quite thorough, beating hardcopy maps in terms of information and content, as well as with the "packing and unpacking" aspect of travel maps and guides.
GPS Navigation successfully operates through the coordination of satellites orbiting the globe. GPS Navigation Receivers, which are the "earth rooted" devices in GPS navigation, synchronize with 24 medium Earth orbiting satellites, allowing GPS Navigation Receivers to determine its precise location, as well as its current direction and the speed it is going, or rather the speed, location and direction the user-on-hand with it is going.
Officially named NAVSTAR GPS, the whole aspect of GPS Navigation was developed by the United States Department of Defense, and was named as such by John Walsh, one of the key steering committee members of the project. The satellites, which are crucial to the successful operation of GPS Navigation, are maintained and managed by the United States Air Force 50th Space Wing, costing about 750 million US Dollars a year. As an entity, GPS Navigation is considered as a public good, and is accessible for everyone, for navigational use, and other "non-threatening" activities.
As an aid to navigation excursions, GPS Navigation systems truly perform well. It basically utilizes three or four of the twenty four satellites going on a medium Earth orbit, to "triangulate" a GPS Navigation receiver's location. GPS Navigation systems are also quite helpful for map-making excursions, land surveying projects, and other commercial and scientific land surveying activities. As time-to-event references GPS Navigation Systems are also quite helpful, particularly when talking about earthquakes, as well as with time-synchronization projects of telecommunication companies.
GPS Navigation Receivers are the "end-user interface" for the GPS system. These receivers operate with an antenna fixed to the signals coming from the satellite, or the satellite system. These GPS navigation receivers are often described by the number of channels one type could handle. The number of channels a GPS navigation receiver supports, says a lot about the number of satellites the GPS navigation receiver could actually connect to, or monitor, simultaneously.
These days GPS Navigation receivers come integrated with various features, the most popular of which would be mp3 audio file playing capabilities. Most GPS Navigation receivers also come with "file based" maps, which come in handy when plotting a traveler's course.
All in all, when it comes to travelling, the use of a GPS navigation receiver would greatly enhance things for travelers.
