Users of GPS devices lose money because of storms

Explosion in the solar energy level of the sun can cause the money to be transferred through the global satellite navigation system (GPS).

In recent years, GPS devices use satellite signals widely used in cars, airplanes, bank transfer transactions . "Social dependence on this technology "There is a risk of great damage from climate change , " said David L. Johnson, director of the US Weather Service Center.

Experts' worries are based on the fact that magnetic storms may occur abnormally, even though their cycle is 11 years. 2001 was the most recent year when the earth suffered from strong storms, then there were big waves in 2003, 2005, 2006. Another strong storm is expected to return in 2011. At that time, the positioning devices satellites will operate inaccurately, not even knowing the location of the receiving point or "off the road".

"Measures to protect GPS systems are not simple and very expensive," said Paul M. Kintner, professor of electronics at Cornell University. "There are two ways: one is to fix the entire GPS antenna so that they reflect sunlight, and the other is to replace all other GPS satellites with a stronger signal."
