Sensor Data Qualification and Consolidation (SDQC) for Real-Time Operation of Launch Systems

摘要

Sensor Data Qualification and Consolidation (SDQC) is an onboard flight software function that implements an algorithmic approach to the determination of sensor data validity. SDQC can mitigate the impact of corrupt data on higher-level flight functions. Additionally, redundant data streams provided by the vehicle's avionics are down-selected and consolidated to simplify and reduce the amount of data that needs to be presented to critical decision-making functions. This paper presents a generalized representation of the SDQC architecture that has been developed for the National Aeronautics and Space Administration's (NASA) Space Launch System (SLS) program and is a variation of the architecture that was developed under NASA's Ares I program. The SLS version of this technology is being implemented as part of the onboard flight software.
