Integration of Automated Safing Responses 2004-01-2550
Environmental Control and Life Support (ECLS) functionality aboard the International Space Station (ISS) includes responding to various emergency conditions. The ISS requirements define three types of emergencies: fire, rapid depressurization, and hazardous or toxic atmosphere. The ISS has automatic integrated vehicle responses to each of these emergencies. These responses are designed to aid the crew in their response actions to the emergencies.
This paper focuses on the integration of ISS responses to these three emergencies. It includes the ISS automatic integrated vehicle response and the initial crew response. Philosophies regarding the generic response to an on-orbit emergency are described. Software responses are defined for modules on orbit up to the addition of the Docking Compartment (DC1) in the assembly sequence. Possible future improvements are also described.
