(Phys.org) —It was an interesting time for physics last week as one team of researchers suggested that elusive dark matter may be detected with GPS satellites. They propose testing the idea that dark matter is arranged ...
(Phys.org) —In today's wireless communication systems, the wireless signals are non-chaotic, meaning they have a well-defined period and frequency. Non-chaotic wireless signals are used in many applications, such as satellite ...
Beyond Earth's atmosphere are swirling clouds of energized particles—ions and electrons—that emanate from the sun. This "solar wind" buffets the magnetosphere, the magnetic force field that surrounds Earth.

(PhysOrg.com) -- If a plan to build new 4G mobile phone base stations in the US goes ahead, engineers say GPS satellite navigation systems will be seriously jammed and huge areas of the country will become GPS dead zones.
A problem that rendered as many as 10,000 U.S. military GPS receivers useless for days is a warning to safeguard a system that enemies would love to disrupt, a defense expert says.

(PhysOrg.com) -- GPS is getting an upgrade costing $8 billion (US), which aims to increase the system's accuracy, improve its reliability, and make the technology even more widespread.
(PhysOrg.com) -- The latest GPS jamming devices are now being used by car thieves in the UK to render stolen cars and trucks undetectable by law enforcement. These devices also pose a threat to airlines and US military overseas.
You can put those maps away. The US Air Force has shot down fears that the space-based Global Positioning System (GPS) is going to crash.
