Top Causes of GPS Interruption

One of the first reasons you might suffer from GPS interruption, is the U.S. Government. They perform interruption tests on GPS systems quite often and there is really nothing you can do about it. You might experience interruption in the following places: China Lake, CA Lax, CA Cedar Rapids, IA White Sands, NM Cape Canaveral, FL Patuxent River, MD Rancho Bernardo, CA Nellis AFB, NV Another cause of interruption is shutdown of two Wide Angle Augmentation System satellites. This system is used as a no-cost differential correction signal for GPS. They are maintained by the FFA or Federal Aviation Administration, but are also available to civilians. The reason for this error is because some systems require the WAAS correction to operate properly. If you think you are experiencing this problem, you need to update your GPS system software. Most GPS manufacturers have information posted on their websites about firmware updates that fix problems just like this. One of the most common reasons is objects blocking a GPS signal. An expert was quoted saying, "anything that can block sunlight can block GPS signals." This could be anything from a building, tree, bridge, or even a vehicle. The only way to solve this problem is to move to an open location that can receive a signal. Additionally, signals can be interrupted by disturbances in the atmosphere where they must travel, and the ionospheric layer is sensitive to solar disturbances which are currently at a solar maximum of an 11 year cycle. One could certainly expect frequent interruption for several years before a lull in the cycle. To learn more about GPS systems and Portable GPS , visit: http://www.gpsstorm.com
