Adjacent-band compatibility assessment inches forward as LightSquared pushes its test approach
from Inside GNSS
The U.S. Department of Transportation is finalizing its blueprint for long-awaited tests to determine the power limits needed to protect GPS receivers. The Adjacent-Band Compatibility Assessment is part of a plan to develop masks — a set of power limits by frequency — for the bands near the GPS L1 signal. Eventually covering all GPS civil receivers present and future, the masks are a way to give potential users of frequencies neighboring the GPS frequencies clear limits against which to measure their plans and proposals.
