So we were reading the latest GPS World Magazine and thought the article, “Act Now to Protect GPS Signal” did a nice job describing the problems industries have with a proposal to develop a cell phone/broadband service that could disrupt GPS. The website has a short and clear report, as well:
Threat to GPS. You may be following the very serious interference issue that threatens the GPS signal. LightSquared is developing high wireless bandwidth capabilities (4G-LTE) for wireless operators. LightSquared received an unnervingly fast-tracked FCC conditional waiver that permits it to broadcast a new terrestrial broadband service from 1,500-watt terrestrial transmitters. This will be in the portion of the L Band that is immediately adjacent to the band used by GPS. The FCC waiver was required as LightSquared’s FCC license only extended to dual-mode phones, but LightSquared wants to offer the option of terrestrial-only, hence the waiver. According to industry experts, the LightSquared terrestrial broadband signal is about 1 billion times the received power of the GPS signal on Earth. This may result in wide-scale GPS interference and jamming worldwide. As a result of ensuing uproar, a working group conducted by LightSquared and the U.S. GPS Industry Council was formed to study the issue.
The National Association of Manufacturers is one of the founding members of the Coalition to Save Our GPS announced earlier this month. Today the coalition announced its new members, representing major industries. From “UPS, TomTom, the American Car Rental Association, Four Key Aviation Groups and Others Sign on to Expanding Coalition Amid Fears of GPS Interference“:
New members representing a variety of concerned industries including aviation, transportation, technology, shipping, and consumer manufacturers are concerned about a serious threat to the Global Positioning System (GPS) – a national utility upon which millions of Americans rely every day.” GPS now provides smaller airports with equivalent levels of safety to those serving large commercial airlines,” said National Business Aviation Association Senior Vice President for Operations and Administration, Steve Brown. “But unlike carrier airports there are no alternate sources of landing guidance if the GPS experiences interference of any kind. The continued protection of satellite navigation is imperative to safety of flight.”
Meanwhile, LightSquared is moving forward on the business front.
