Abstract
In the continuous effort to computerize antenna pointing and control systems at the DSN stations, sample data systems are required. As a result of modular subsystems being readily available commercially, the sample data systems are designed in accordance with a decentralized system design philosophy. A number of smaller subsystems are located physically close to the data sources. The subsystems feed data to collection centers which in turn feed data to the computer. The only connection between subsystems, collection centers, and computer is a single coaxial cable. Since there is no separate clock signal, bit synchronization must be extracted from the data signal in order to recover the serial binary data. This article describes a particularly simple bit synchronizer phase-locked loop especially designed for this noise-free environment. The performance of the loop has been analyzed and qualitatively verified on a laboratory breadboard model.
