LightSquared Testing: the Sequel

摘要

The U.S. Department of Transportation (DoT) announced in March that testing for the Adjacent Band Compatibility (ABC) Assessment will start in April. Conducted at the U.S. Army Research Laboratory, White Sands Missile Range, the tests seek to determine power limits for spectrum bands near the GPS LI signal. Later tests will focus on potential interference with the L5 signal and frequencies of other satellite navigation constellations.
