Webfor the L1 and L2 bands. This paper synopsizes the resulting M code signal design, which is to be implemented in modernized satellites and in a new generation of receivers. The paper summarizes the history that led to GPS Modernization with a new military signal on L1 and L2. After an overview of the M code signal design, the paper Having reached full operational capability on July 17, 1995 the GPS system had completed its original design goals. However, additional advances in technology and new demands on the existing system led to the effort to "modernize" the GPS system. Announcements from the Vice President and the White House in 1998 heralded the beginning of these changes and in 2000, the U.S. Congress reaffirmed the effort, referred to as GPS III. how did martha stewart start her business
