Boston

Between 1999 and 2006, Bicycling magazine named Boston three times as one of the worst cities in the US for cycling; regardless, it has one of the highest rates of bicycle commuting. In 2008, as a consequence of improvements made to bicycling conditions within the city, the same magazine put Boston on its "Five for the Future" list as a "Future Best City" for biking, and Boston's bicycle commuting percentage increased from 1% in 2000 to 2.1% in 2009. The bikeshare program called Hubway launched in late July 2011, logging more than 140,000 rides before the close of its first season. The neighboring municipalities of Cambridge, Somerville, and Brookline joined the Hubway program in summer 2012.

Unlike the American GPS, Russian GLONASS, and European Galileo systems, which use medium Earth orbit satellites, BeiDou-1 uses satellites in geostationary orbit. This means that the system does not require a large constellation of satellites, but it also limits the coverage to areas on Earth where the satellites are visible. The area that can be serviced is from longitude 70°E to 140°E and from latitude 5°N to 55°N. A frequency of the system is 2491.75 MHz.

Question: What service area is covered by the BeiDou-1 system?

The ranging signals are based on the CDMA principle and have complex structure typical of Galileo or modernized GPS. Similar to the other GNSS, there will be two levels of positioning service: open and restricted (military). The public service shall be available globally to general users. When all the currently planned GNSS systems are deployed, the users will benefit from the use of a total constellation of 75+ satellites, which will significantly improve all the aspects of positioning, especially availability of the signals in so-called urban canyons. The general designer of the COMPASS navigation system is Sun Jiadong, who is also the general designer of its predecessor, the original BeiDou navigation system.
