The Diagnostic Solution Assistant (DSA) provides diagnostics for space hardware and subsystems. Advanced Honewell ‘smart’ model-based technology performs the real-time fault detection, isolation and diagnostics. This model-based technology provides 24-hour access to the operational knowledge of the system experts. The complexity of the International Space Station (ISS) and other manned space vehicles requires that a full staff of ground based system diagnosis experts be trained and available at all times. Response to critical situations must be immediate no matter what time of the day or night. Installation of new systems plus normal staff turnover cause personnel to be in training constantly. Domain knowledge lost due to staff attrition may also never be regained. All of these factors lead to higher cost ground based flight system monitoring stations and sub-optimal efficiency. The Diagnostic Solution Assistant (DSA) provides a solution to these issues. The DSA can be deployed into the ISS Mission Control Center to enhance Flight Controller awareness and decision making. DSA can be utilized onboard the vehicle to enhance crew awareness and potentially offload the crew in time- or safety-critical situations. The DSA can be used to isolate and diagnose faults during flight preparation, thus reducing the overall vehicle turn-around time. In addition to having diagnostic capability, DSA is a tremendous requirements and operations knowledge capture tool that could streamline training for the flight controller and crew, and facilitate the rapid location of important information. © 2000 American Institute of Physics.
