Department of Defense World Geodetic System 1984: Its Definition and Relationships with Local Geodetic Systems. Second Edition
Abstract
This technical report presents the Department of Defense (DoD) World Geodetic System 1984 (WGS 84) developed as a replacement for WGS 72. The development of WGS 84 was initiated for the purpose of providing the more accurate geodetic and gravitational data required by DoD navigation and weapon systems. The new system represents the Defense Mapping Agency's modeling of the earth from a geometric, geodetic, and gravitational standpoint using data, techniques, and technology available through early 1984. Additional Doppler and GPS survey information has since been used to update the datum transformation tables.
