    The Global Positioning System employs a constellation of 24 
satellites and associated ground stations to provide continuously 
transmitted world-wide positioning, navigation, and timing signals for 
use with appropriately configured GPS user equipment. The current 
generation GPS space vehicles transmit signals at the L1 and L2 
frequencies. In the future, new civil signals will be transmitted on 
the L2 and L5 frequencies. The international civilian and military 
communities employ the dual use Global Positioning System.
