AKA: Global Positioning System;Navstar. Status: Operational 2010. First Launch: 2010-05-28. Last Launch: 2015-10-31. Number: 11 . Gross mass: 1,545 kg (3,406 lb). Height: 3.93 m (12.89 ft). Span: 13.11 m (43.01 ft).

Improvements included an extended design life of 12 years, faster processors with more memory, and a new civil signal on a third frequency. The first Block IIF satellite was scheduled to launch in 2005.

In 1996 Boeing was selected for a contract with options for up to 33 Block IIF satellites. In 2001 the contract was revised to produce 12 modernized Block IIF satellites.

Electric System: 2.40 average kW.

Spacecraft: GPS Block 2F. USAF Sat Cat: 36585 . COSPAR: 2010-022A. Apogee: 20,225 km (12,567 mi). Perigee: 20,188 km (12,544 mi). Inclination: 55.00 deg. Period: 719.00 min.

  First Block IIF Global Positioning System satellite. Supported the L1M and L2M military GPS channels, the L2C civilian channel and a new L5 civilian channel. Also included a nuclear explosion detection system. The IIF system replaces earlier Block I, Block II, and IIA series built by Rockwell/Seal Beach (now part of Boeing) and Block IIR satellites built by Lockheed Martin/Valley Forge.

Spacecraft: GPS Block 2F. USAF Sat Cat: 38833 . COSPAR: 2012-053A. Apogee: 20,192 km (12,546 mi). Perigee: 20,174 km (12,535 mi). Inclination: 55.00 deg. Period: 718.00 min.

  Third GPS Block IIF satellite, spacecraft 65; replaced SVN 39 in the Navstar constellation. The upper stage and payload first entered a 163 km x 394 km x 41.6 deg parking orbit, followed by a 254 km x 20448 km x 43.3 deg transfer orbit and then a third burn into the final 20426 km x 20481 km x 55.0 deg circular orbit where the satellite was deployed. The RL-10 second stage engine operated at lower than planned thrust during the first two burns, but onboard software compensated by increasing the duration of the engine firings.
