Space systems are costly, high-risk endeavors. The launch phase of a space mission presents its own set of challenges, and payloads are carefully engineered to ensure that they survive the launch. Of particular importance for payload survival is the vibro-acoustic environment during the launch. To better predict this environment, The Aerospace Corporation is developing the Vibro-acoustic Intelligent System for Predicting Environments, Risk, and Specifications (VISPERS), a Java-based tool suite that allow analysts to condition, filter, and analyze vibro-acoustic data from the telemetry gathered during spacecraft launches. VISPERS contains a Time History Editor (THE), waveform analysis tools (PDF, Vail, Tact), a predictor for the response of a payload to a shock (Shock Response Spectrum) and a tool that computes the power spectral densities of the vibrations and sounds occurring during a launch (MAXIMAX Analysis Tool). VISPERS permits one to process sensor data in batch mode and to plot the raw data and the analytical results. This overview of VISPERS highlights the major tools and components of VISPERS as well as their use in the analysis of space launch telemetry.
