Evaluation of the generic open architecture framework [for weapons systems]

The Weapon Systems Annex proposes a framework similar to the DoD Technical Reference Model cited in the Joint Technical Architecture (JTA) but one whose governing source is the Society of Automotive Engineers (SAE). The SAE developed a technical reference model based on a NASA initiative for space flight systems software. The model is named the Generic Open Architecture (GOA) Framework. This GOA Framework was investigated in a study for possible modification and inclusion in the Weapon Systems Annex of the JTA. The analysis showed that a GOA Framework is useful as a reference model for weapons platforms. Benefits from this framework are best represented by two fundamental categories: software portability and systems interoperability. These two categories are presented as open systems stacks.
