Innovators at NASA's Johnson Space Center have developed a software tool that plots the location of satellites for post-flight analysis. The global positioning system (GPS) Receiver Analysis Tool (RAT) reads telemetry information from a GPS receiver and provides a concise method to determine the performance of the receiver. As the telemetry input file is read, an analyst can see the plotted satellites and telemetry information change in animated form. The analyst can halt the animation and generate high-quality PostScript® technology images of the plot suitable for importing into post-flight reports.
