In a response similar to that of the ultrawideband controversy nearly 10 years ago, the GNSS community has expressed dire concern that, if implemented, the Lightsquared initiative could cause serious problems for millions of users in the United States.

Within five years, given the plans of GNSS system operators, the number of satellites will reach 90 or more - with even more types of signals broadcast on even more frequencies. All of which represents good news and maybe some not-such-good news for GNSS product designers, service providers, and end users. (more) |
