GPS users to benefit from more precise data

The accuracy of the global positioning system (GPS) has been improved with the recent handover of a fifth Boeing GPS IIF satellite to the US Air Force. The newest addition to the GPS constellation increases the precision of position, navigation and timing data sent to users around the world.

The satellite was launched 20 February. The Air Force, which operates the GPS system, and Boeing have now completed deployment and validation of the spacecraft’s systems, stabilising the vehicle and activating its navigation payload.

Boeing is preparing the next GPS IIF satellite - the sixth of 12 - for a second-quarter launch. The GPS IIF delivers improved accuracy, greater security and anti-jam capabilities while maintaining baseline legacy GPS performance.

Since the first launch in 1978, Boeing-built GPS satellites have accumulated the equivalent of more than 500 years of on-orbit operation.
