Ag groups concerned about threat of GPS interference
Representatives from major ag organizations met recently in Washington to hear about potential interference with GPS systems if a pending waiver is granted. The issue involves a company called LightSquared that is working on wireless broadband. LightSquared has asked the FCC to allow it more on-land use of the electromagnetic spectrum, including an area bordering that used by GPS devices. If the proposed changes are made, tests show GPS interference could occur because of what are called “out of band emissions”—meaning signal leaks from one band into another—or from “front end saturation”—meaning receivers take in signals from another band. We discussed the issue with RJ Karney, who works on rural development issues for the American Farm Bureau Federation.
