A former resident of Maryland with more than a decade of experience in the software development sector, Anthony Wright served as a strike fighter pilot with the United States Navy. In this position, Anthony Wright introduced GPS weapons to the West Coast Hornet community by developing training curricula for both the Joint Standoff Weapon (JSOW) and Joint Direct Attack Munition (JDAM).

An efficient smart-bomb technology, Joint Direct Attack Munition is an advanced program designed to add sophisticated rear guidance functionality to mitigate limitations of existing “dumb” bombs. Currently, the U.S. Air Force uses JDAM to launch multiple heavy bombs, including the 2000-pound BLU 109 and 1000-pound BLU 110.

Essentially, JDAM implemented aircraft have control computers, GPS receivers, and inertial guidance systems. The location of the bomb in space is provided by the inertial guidance system and GPS receiver. The GPS receiver defines the bomb's position by interpreting GPS satellite signals. At the same time, the inertial guidance system dynamically monitors the bomb's movement, providing real-time information of its current track from its launch position.

When the bomb is about to be dropped, the aircraft's GPS receiver will help pinpoint defined targets on the ground. Immediately before the bomb is released, the aircraft's GPS feeds the bomb's computer with data containing its current position and the target's coordinates.
