Cybersecurity Bills Could Reshape GPS Anti-Interference Efforts

Legislation moving through Congress could reshape efforts to counter GPS interference as the government steps up its efforts to fight cybercrime and protect critical systems like the power grid and communications networks.

Though cybersecurity generally focuses on protecting information systems the broad definitions in some legislation now on the Hill appear to encompass GPS support systems, some user communities, and even the constellation itself.

British Military Claims Patent on GPS, Galileo Civil Signal Structure

Variations on the common GPS/Galileo MBOC signal

The British military establishment is seeking royalties from GPS receiver manufacturers, asserting it holds a patent on the technology at the heart of the new GPS and Galileo civil signals.

Should U.S. manufacturers have to pay royalties, American GPS users, who have already paid for the GPS constellation and made it available to the world free of charge, could find themselves spending more to use its location capabilities. Sources said the development could undermine relations between the U.S. and the European Union (EU), which have cooperated for years to develop a common signal at the L1/E1 frequency centered at 1575.42 MHz.
