GPS jammers work by disrupting frequencies in one of the often used GPS bands. GPS system signals are pretty weak, so it’s fairly simple for a jammer to interrupt or interfere with receivers such as portable navigation devices.

A recent report by the U.K.’s Royal Academy of Engineering on the vulnerability of the GPS system said that jammers are a threat that could affect both individual GPS devices and the GPS system’s basic infrastructure. Although the threat of someone using GPS jammers in a major terrorist attack is quite low, it is possible, and the military is certainly keeping that in mind as it has been trying to protect the GPS system from these types of weaknesses.

But the jammers ability to interfere with individual navigation devices is a much more likely scenario. GPS jammers can wreak havoc when they get into the wrong hands. Criminals and car thieves can use GPS jammers to get away with bad behavior

he recent 8.9 magnitude earthquake in Japan will not only leave an everlasting impression on the country, but globally as a result of the quake’s effect on the rotation of the Earth and GPS coordinates, according to Richard Gross, a geophysicist at NASA’s Jet Propulsion Laboratory. The intense earthquake that struck Japan on March 11, 2011, has accelerated Earth’s spin – which has has shortened the length of Earth’s day by a fraction and shifted how the planet’s mass is distributed.

The earthquake shortened of the length of the 24-hour day by 1.8 microseconds. Aftershocks in Japan could continue to result in further changes to GPS coordinates, the length of day, and the shifting of the Earth’s axis.
