GPS-based TSPI Instrumentation... Past, Present, Future - a Three-part Series Part 3, Future Technology

摘要

GPS instrumentation made its debut on the test ranges in the early 1990's. It has proven to be a cost-effective source of highly accurate, world-wide, three-dimensional position, velocity and time. Today, GPS is widely employed as a preferred source of Time-Space-Position Information (TSPI) for most Test and Evaluation (T&E) applications. However, GPS-based instrumentation capabilities and technologies provide opportunities for expanded end-use that should/must be considered.
