KSR ground-based data processing equipment and software have been designed to minimize human interface requirements. The computer hardware is both powerful and portable. The software is easy to use and contains routines for calibration, engineering units conversion, error correction, smoothing, curve fitting and plotting, plus complex data analysis capabilities. In addition, the software accommodates user defined calculations on the measured data. Data turnaround is fast and the data analysis process is controlled by the program engineer. Our sophisticated data processing system and software converts recorded data into a single flight test data base that can be analyzed and processed to produce final report quality plots at the test site.
