China is building up its global satellite navigation system BeiDou (COMPASS) that is intended to cover the world by 2020. That’s the word from the country’s first Satellite Navigation Conference, in Beijing. Developed and operated by China, BeiDou is designed to provide accurate real-time military and civil service to national security, social and economic development.

During flight testing, Boeing technical personnel have historically used a differential GPS (DGPS) system as the position truth reference for validating various production systems on the airplane. The majority of those tests occur on or near remote runways to capture specific environmental conditions.

GPS IIF-SV1 launch. United Launch Alliance photo[Updated July 22, 2010] Air Force officials at the GPS Wing have confirmed that higher-the-expected range residuals detected by researchers at the German Aerospace Center (DLR) are appearing in signals transmitted by the first GPS IIF satellite, designated SVN/62/PRN25.
But the Air Force and Boeing Space and Intelligence Systems, which built the spacecraft, point out SVN62 is currently performing within specifications, and the signal phenomenon does not appear likely to have any significant effect on GPS positioning when the satellite is declared operational.
