New Air Force Satellites launched to improve accuracy to 42 cm


Back in 1978, the first GPS satellite was launched into orbit. Since then, the Air Force has improved their satellite design and released new versions of GPS satellites in blocks. Starting with Block I, the Air Force has moved through Block IIA, Block IIR, Block IIR-M, and today they’ve completed the launch of their Block IIF series.

While only 30 GPS satellites are currently operational, 50 have been launched in total. The most recent group of Block IIF satellites were launched between May of 2010 and today.

Col. Steve Whitney, the director of the Global Positioning System Directorate, said that the last leg of launches had “one of the most aggressive launch schedules of the last 20 years.” There were 7 Block IIF satellites launched in just over 21 months.
