| 2.2.4-4-1 Ensure interface requirements are defined |
Phase A |
Phase B |
Phase C |
|
Ensure all interface requirements contain adequate margins for performance. Ensure interfaces are defined at the lowest levels of integration. Ensure verification methods include use of validated simulators and drivers. Ensure the external interface definition and associated requirements are adequate and complete. Ensure that all space vehicle external interfaces are captured as part of the space vehicle segment test planning effort. These interfaces include all space segment interfaces including GSE and other space assets. Ensure all external interfaces identified and reflected in Interface Control Specifications.
