Posted: January 5, 2011 Later photographs from 1985 provide another look at the only time a space shuttle vehicle ever stood at Vandenberg Air Force Base's Space Launch Complex 6. The program of launching military space shuttle flights into polar orbits from California would be cancelled before any missions ever took off and the SLC-6 pad eventually transferred to the Delta 4 rocket.Credit: U.S. Air Force photos Credit: U.S. Air Force photos | | | | 2014 Spaceflight Now Inc.First ULA Delta 2 launchPosted: December 15, 2006The first United Launch Alliance Delta 2 rocket ascends from Vandenberg Air Force Base carrying a classified payload for the National Reconnaissance Office.

Credit: Stephen Clark/Spaceflight Now "GPS is used by nearly a billion people worldwide for everything from farming and aviation to public safety, disaster relief and recreation, not to mention its military purpose of providing precision navigation and timing to combat forces," said Col. David Madden, the Air Force's GPS Wing commander.Some 60 satellites have been launched for the system over the past three decades, initially testing the concept and later assembling the operational grid in use today.And now the Air Force has successfully launched the first spacecraft in the Block 2F series, a new breed of GPS satellite that features even higher accuracy, enhanced internal clocks, longer life and reprogrammable onboard processors to evolve with future needs."GPS 2F will increase the signal power, precision and capacity of the system, and form the core of the GPS constellation for years to come," said Madden.A United Launch Alliance Delta 4 rocket, flying in its Medium+ variant equipped with a pair of solid-fuel strap-on motors, roared into Cape Canaveral's nighttime sky at 11:00 p.m. EDT carrying the GPS 2F-1 satellite nestled in its nose cone.Unlike GPS launches over the past 20 years that relied on Delta 2 rockets for delivery into orbit, the new-generation 2F satellites also got upgraded to the larger, more capable Delta 4 and Atlas 5 fleets of boosters in the Air Force's Evolved Expendable Launch Vehicle program. Although the Delta 2 was highly reliable, it wasn't powerful enough to inject the GPS satellites directly into the orbiting constellation. The birds needed their own kick motor and several days to reach the desired destination.That all changed Thursday night when the Delta 4's upper stage performed three firings that methodically hauled the GPS 2F-1 satellite into a circular orbit 11,000 nautical miles above the planet. In just three-and-a-half hours, the $121 million spacecraft had arrived at the proper altitude and completely bypassed the circuitous route of its predecessors.

"GPS 2F is the culmination of our deep experience with 39 successful satellites from previous missions, representing more than 30 years of teamwork with the Air Force.""Normally when you are launching the first-of-a-kind satellite you'd be really worried because it's a system that's more complex than the last generation. In this case, we've added capability but it's built on a foundation of success from the 2A program, which was a massively successful program," Madden said.Today's GPS constellation is comprised of 30 functioning satellites, including 11 Block 2A's made by Boeing, 12 2R's and 7 2R-Modernized spacecraft built by Lockheed Martin. Their ages range from the teens to less than a year old."The current GPS constellation has the most satellites and the greatest capability ever. We're committed to maintaining our current level of service, as well as striving to improve service and capability through on-going modernization efforts," Madden said."The U.S. Air Force and Air Force Space Command have been diligent stewards of GPS since its conception in the 1970s and continue its commitment to this critical component of our national infrastructure."GPS satellites emit continuous navigation signals that allow users to find their position in latitude, longitude and altitude and determine time. Originally built as a tool for the U.S. military, the utility has spread across the wor
