GPS Correction Methods
The Global positioning system (GPS) is a group of satellites that allow people to determine their current location if they have a standard GPS receiver. The receivers are usually accurate by 5 meters; they know their current location by calculating the amount of time it takes for a signal to travel from the satellite in space to the receiver. If a more precise location is needed, the GPS data has to be corrected. This can be done in real time or after the data has been recorded (post processing). Theoretically, all methods of correcting the data should yield the same result. However, the results usually differ because of the different location reference stations, as well as the different equipment being used. The different equipment employs different techniques of correcting the error, and this results in different outcomes. The various methods include DGPS beacon corrections, Wide-Area Augmentation System (WAAS), Satellite Service Providers, Using L-Band Frequencies, Canadian DGPS and Post processed GPS Data.
The DGPS beacon correction is used in America by the Coast Guard. They have installed two control centers and over 60 beacon stations along the American coastline and watercourses. These beacons collect data then send it to control stations for correction, thus improving the accuracy of receivers. In other words, compared to the normal way GPS receivers work, a DGPS beacon transmitter site has a reference point that has been accurately surveyed (altitude, latitude, and longitude). Therefore, it calculates the time it takes for the signal to reach the receiver. Considerin...
