Please note that the content of this book primarily consists of articles available from Wikipedia or other free sources online. The Minitrack Network, was the first U.S. satellite tracking network to become operational, in 1957. It was used to track the flights of Sputnik, Vanguard, Explorer, and other early space efforts. Minitrack was the progenitor of Spacecraft Tracking and Data Acquisition Network and the Manned Space Flight Network. The optical and radar approaches did not require a cooperative target, but had the major problem of acquisition, or finding the target in the first place, since they had very small fields of view. The NRL proposal needed a transmitter on the target, but could easily measure a target anywhere in a wide field of view. The NRL proposal was accepted and turned into the basis of the Minitrack stations.
