China fired into orbit Wednesday its second satellite in a program to build an alternative to the global positioning system based on U.S. satellites. The geostationary satellite is one of a series being slung into space to form the Beidou, or “Compass,” navigation system, the official Xinhua News Agency said, calling the system a “crucial part of the country’s space infrastructure.” The system is touted by China as an alternative to the U.S. satellite GPS network, the dominant positioning system.
