## Background 

The Global Positioning System employs a constellation of 24 satellites to provide continuously transmitted positioning/navigation signals for use with appropriately configured GPS user equipment. The GPS satellite vehicles transmit signals at the L2 and L5 (future) frequencies to allow GPS user equipment to perform its positioning and navigation functions. The civilian and military communities employ the Global Positioning System.
