Gps Instrumentation

During the past two decades, the civilian as well as military GPS instrumentation evolved through several stages of design and implementation, focusing primarily on achieving an enhanced reliability of positioning and timing, modularization, and miniaturization. In addition, one of the most important aspects, especially for the civilian market, has been the decreased cost of the receivers, as the explosion of GPS applications calls for a variety of low-cost, application-oriented, and reliable equipment. By far, the majority of the receivers manufactured today are of the C/A-code single-frequency type. However, for the high-precision geodetic applications, the dual-frequency solution is standard. Even though the civilian and military receivers, as well as application-oriented instruments, have evolved in different directions, one might pose the following question: Are
