A new U.S. National Space Policy announced on June 28, 2010 by the White House says that foreign GNSS services may be used “to augment and strengthen the resiliency of GPS.”
In a document that underlines the Obama administration’s intention to rely more on international cooperation in space-related activities and “energize competitive domestic industries to participate in global markets,” the new policy reaffirms recent efforts “to engage with foreign GNSS providers to encourage compatibility and interoperability, promote transparency in civil service provision, and enable market access for U.S.industry.”
In a measure of the prominence of GPS in the nation's space-related activities, President Barack Obama noted in his statement on the new policy, "We can point to satellites orbiting hundreds of miles overhead that can identify our location within inches, or communications systems that allow information to flow around the world as never before."
The policy document charges U.S. governmental departments and agencies to identify potential areas for international cooperation including GNSS and related fields such as geospatial information products and services, Earth science and observation, environmental monitoring, disaster mitigation and relief, and search and rescue.
