Boeing completed initial electromagnetic compatibility and interference testing of the first GPS 2F satellite, the company announced Feb. 2.

The test, conducted at the company’s Satellite Development Center in El Segundo, Calif., verified that radiated emissions and RF compatibility design complies with system specifications and variants of the Evolved Expendable Launch Vehicle that may be used to launch the spacecraft. An additional test using flight hardware will be completed prior to delivery.

Boeing is building nine Block 2F satellites under a $1.3 billion contract from the U.S. Air Force. The first satellite is scheduled to be launched in 2008.
