Bankrupt LightSquared sues GPS companies

Bankrupt LightSquared sued leaders in the GPS industry on Friday, including Deere & Co. and Garmin International. LightSquared says the companies kept quiet about interference concerns stemming from its wireless network until the company had already pumped $4 billion into building it, according to a Reuters report. In a 65-page lawsuit in U.S. Bankruptcy Court in New York, where LightSquared is fighting to keep control of its spectrum, the company alleged that farm equipment maker Deere, and GPS companies Garmin and Trimble Navigation Ltd., led it to believe its network would not interfere with global positioning system devices.
