The first in a series of new and improved GPS satellites (GPS IIF) has been launched by the U.S. Air Force. It should come into active (healthy) service at the end of Aug 2010. The satellites in the new series will offer improved position accuracy and have a stronger signal for better reception - good news for users in dense tropical rain forests, for example.Previous reports had pointed to the issue with the ageing GPS (Navstar) fleet. The GPS constellation is now reported to have 30 operational satellites; and with Russia's GLONASS, the European Union's Galileo, China's Beidou-1 and Compass, India's IRNSS and Japan's QZSS at various stages of operation, upgrade or development, that popular question might just become even more prevalent.
