Auxiliary Payload Sensor System Simulation Software (APSSim) provides a simulation of the seismometer used in the Insight (Interior Exploration using Seismic Investigations, Geodesy, and Heat Transport) mission. The software takes recorded or simulated APSS data as an input, preprocesses the input data, and generates APSS data packets. The software also has fault injection capabilities that enable flight software developers to inject faults from the APSSim to test their software in various scenarios. It also allows users to run multiple instances of APSSim for batch and overnight testing. It gives the user a tool to thoroughly test their applications in a way that cannot be done otherwise.

This work was done by Shui H. Motaghedi, Johnny T. Chang, and Lermont Khachikyan of Caltech for NASA’s Jet Propulsion Laboratory.
