  • GPS For Newbies Help India Learning -
    GPS design is based partly on ground-based radio navigation systems developed in the early 1940’s that were used in World War II. These systems were named LORAN and Decca Navigator and were focused on knowing where the enemy was so they could either attack or retreat depending on the size of the forces.
