Second IIF Satellite Prepped for Launch

By |December 19th, 2014|

BY JUSTIN RAY SPACEFLIGHT NOW Posted: June 27, 2011 A Global Positioning System satellite has been loaded aboard its ride to space, arriving Monday at Cape Canaveral’s Complex 37 for mounting atop the United Launch Alliance Delta 4 rocket. Liftoff of the GPS 2F-2 spacecraft is scheduled for July 14 during a 19-minute window extending from 2:49 to 3:08 a.m. EDT (0649-0708 GMT). The launch is timed to deliver the satellite into the GPS constellation to replace a 20-year craft that has long exceeded its expected lifespan. GPS satellites fly about 11,000 miles above the planet and emit continuous navigation signals that allow users to find their precise position in latitude, longitude and altitude and determine time. Originally built for the U.S. military, the GPS service has spread across the world as an indispensable commercial utility. […]

By |December 19th, 2014|

A United Launch Alliance Delta II rocket successfully launched the Air Force’s Global Positioning Satellite IIR-20(M) into orbit from Space Launch Complex 17A at 4:34 a.m., EDT. This was the 47th successful GPS launch for the Delta II in its storied 20-year history. The very first Delta II launch on Feb. 14, 1989 was the NAVSTAR II-1 launch. NAVSTAR is now commonly known as GPS. […]

GPS IIF-4 Successfully Launched

By |May 21st, 2013|

5/16/2013 – LOS ANGELES AIR FORCE BASE, Calif. — A U.S. Air Force Global Positioning System (GPS) satellite built by Boeing was successfully launched May 15. The fourth GPS IIF satellite, Space Vehicle Number (SVN) 66, was carried aboard aUnited Launch Alliance Atlas V Launch Vehicle at 5:38 p.m. EDT from Cape Canaveral Air Force Station, Fla. The new capabilities of the IIF satellites will provide greater navigational accuracy through improvements in atomic clock technology; a more robust signal for commercial aviation and safety-of-life applications, known as the new third civil signal (L5); and a 12-year design life providing long-term service. These upgrades improved anti-jam capabilities for the warfighter and improved security for military and civil users around the world. […]

Braxton Called in from Bullpen for IIF Relief

By |August 9th, 2010|

The Launch/Early Orbit, Anomaly Resolution, and Disposal Operations (LADO) system experts from Braxton Technologies were called in to contact the satellite and regain control, and subsequently turn the wayward IIF satellite back over to the AEP control segment. IIF-1/SVN62 Arrives on Station During the week of August 2, the Architecture Evolution Plan (AEP) software installed at the master control station at 50th Space Wing Space Operations Centers (SOC) temporarily lost contact with or command and control (C2) of the IIF satellite undergoing testing and initialization, during a Delta V maneuver. The Launch/Early Orbit, Anomaly Resolution, and Disposal Operations (LADO) system experts from Braxton Technologies were called in to contact the satellite and regain control, and subsequently turn the wayward IIF satellite back over to the AEP control segment.
