DESCRIPTION
Surely they have heard of WAAS, and its improvements in the field of navigation and location … But what is the technology WAAS. It is an improved tracking system that allows us to have a greater accuracy in determining a GPS position.
The current accuracy of GPS equipment, is approximately 15 meters, so always Cuena a significant position error. Now with the new devices WAAS-enabled GPS navigation, such precision in position, is reduced to within 3 meters.
? 100 m: original GPS system (with SA).
? 15 m: current GPS system (without SA).
? 3-5 m: System Differential GPS (DGPS).
? <3 meters: Typical WAAS Accuracy
ORIGIN:
The origins of WAAS technology, arose from the need for greater precision in the landing of aircraft. This technology is being developed by the Federal Aviation Administration (FAA) and Department of Transportation (DOT).
Because GPS technology, did not cover the needs of accuracy, WAAS technology is created, a correction on the GPS signal. This correction is necessary, because of atmospheric disturbances produced in the ionosphere, possible errors in the satellite orbit.
OPERATION:
WAAS consists of approximately 25 points of land, which monitor the GPS satellites, and the data they send, over the territory of the United States.
Two master stations, collect data from reference stations and by contrast, creates an error report that you can have the GPS signal and send it to recipients who have WAAS capability. This is done through satellites on Ecuador, or geostationary satellites. Automatically, on the devices themselves, the signal is corrected, and thus, the accuracy increases with the receiver, and the margin of error decreases.
COVERAGE:
But today, the WAAS system is available only in North America, although its signal is usually picked up in Spain, so it is recommended that navigation systems are purchased, have this technology. Formats exist in other continents like Asia, MSAS or EGNOS in Europe, that will give us the details and appropriate corrections in the location of the WAAS.
