Process Model for Defining Space Sensing and Situational Awareness Requirements
Abstract
A process model for defining systems for space sensing and space situational awareness is presented. The paper concentrates on eight steps for determining the requirements to include: decision maker needs, system requirements, exploitation methods and vulnerabilities, critical capabilities, and identify attack scenarios. Utilization of the USAF anti-tamper (AT) implementation process as a process model departure point for the space sensing and situational awareness (SSSA) mission area is presented. The AT implementation process model, as an accepted process application pertains directly to the analysis of military space system sensing requirements. In the paper a new process model is presented with generic SSSA examples and questions for each process step leading to preliminary environmental requirements. The resulting SSSA requirements analysis model allows government program managers and acquisition officials to trade cost, schedule and technical performance of identified SSSA solutions against the identified vulnerabilities and allocates the solution set between spacecraft, ground system, or other sensing architectures. The model allows the requirements analyst to frame sensing solutions against the attack scenarios such that decision makers can weigh cost versus benefit to protecting the critical space capability. The resulting model provides for a common lexicon and taxonomy for requirements discussion between NATO members. The paper also introduces the temporal quality to the SSSA needs based on the constant march of technology by introducing a concept for updating the SSSA requirements analysis based on the periodicity of Moore's law.
