Researchers Find Global Positioning System Is Significantly Impacted by Powerful Solar Radio Burst (View Original Story)
Source: Posted: 04-04-2007 at 03:00:51
| During an unprecedented solar eruption last December, researchers at Cornell University confirmed solar radio bursts can have a serious impact on the Global Positioning System (GPS) and other communication technologies using radio waves. The findings were announced in Washington, D.C., at the first Space Weather Enterprise Forum - an assembly of academic, government and private sector scientists focused on examining the Earth's ever-increasing vulnerability to space weather impacts. Solar radio bursts begin with a solar flare that injects high-energy electrons into the solar upper atmosphere. Radio waves are produced which then propagate to the Earth and cover a broad frequency range. The radio waves act as noise over these frequencies, including those used by GPS and other navigational systems which can degrade a signal. |
