Summary
[edit]DescriptionCol Wilbert F Craig III (2000467079).jpg |
English: Developed the United States Air Force satellite tracking ephemeredes, algorithms, and equations in the 1950s that made SPACETRACK possible. While at Kirtland Air Force Base, N.M., he organized the local “Moonwatch” project by creating one of the world’s first sites for satellite tracking. After the launch of Sputnik, he developed a basic radar tracking system to predict its orbital location for the Air Force. Colonel Craig also participated in the project that first introduced space as a potentially primary element in strategic warfare. In early 1961, he was among the initial cadre to join the 1st Aerospace Control Squadron and train as an orbital analyst under Program 437. |
