Who operates GPS for the U.S. government?
Currently 31 GPS satellites orbit the Earth at an altitude of approximately 11,000 miles providing users with accurate information on position, velocity, and time anywhere in the world and in all weather conditions. GPS is operated and maintained by the Department of Defense (DoD).
When did GPS become fully functional in the United States?
The Global Positioning System marked its 25th year of operation on April 27. On this date in 1995, the system reached full operational capability, meaning the system met all performance requirements. U.S. Air Force Space Command formally announced the milestone three months later. “This is a major milestone,” Gen.

How accurate is US military GPS?
The government provides the GPS signal in space with a global average user range rate error (URRE) of ≤0.006 m/sec over any 3-second interval, with 95% probability.
Can I use Galileo in USA?
Following this decision, consumers and industry in the U.S. will be permitted to access certain satellite signals from the Galileo system to be used in combination with the U.S. Global Positioning System ( GPS ), allowing them to benefit from improved availability, reliability, and resiliency of these position.
Does Galileo GPS work in USA?
Users in the U.S. can’t see Galileo satellites in GPSTest, but it’s not due to any device or satellite technology limitation — it’s due to a Federal Communication Commission (FCC) regulatory restriction.
Can the U.S. restrict GPS?
No. Since it was declared operational in 1995, the Global Positioning System has never been deactivated, despite U.S. involvement in wars, anti-terrorism, and other military activities.
