With the nation's growing reliance on GPS for a wide range of functionality, including agriculture applications, the U.S. government has committed to its ongoing maintenance and improvement.

Earlier last month that commitment was honored with the launch of a new Global Positioning System satellite. It is the latest in a series of upgraded navigation beacons with improved accuracy and longevity.

According to a story by, the $121.3 million GPS 2F-4 satellite is the fourth in a series of 12 being built by Boeing.

The new satellite joins a constellation of 30 other Global Positioning System navigation stations operating in six different orbital planes. At least four satellites fly in each plane and multiple spacecraft are above the horizon at any given moment as viewed from any point on Earth.
