Software • Recommendation Software-1 Establish and use multiple assurance levels for software design, verification and qualification processes to support these levels. This is to reduce initial software cost as well as maintenance costs by only doing the effort as required by the safety analysis • Recommendation Software-2 Establish standard software architectures, supporting services and execution environment for all LSS elements supporting: Hard Real-time Environment, Software Real-time Environment and Windows-like or equivalent. This is to allow for software to be developed and hosted in an environment best suited for that application (GN&C in Hard Real-Time & Excel in Windows type OS) • Recommendation Software-3 Establish common software repositories to eliminate replication of software pieces for multiple vehicles. This is to reduce cost and increase quality by exposing building blocks to wider use and implicit testing. • Recommendation Software-4 Establish data standards for communications between software in the different sensors, effectors, computing unit (e.g. expansion of OPC - OLE for Process Control to include common vocabulary/taxonomy/ontology). This is to allow for remote data access to remote equipment and reduce IO software development costs. 20 LSS Avionics Concept Study – Final Presentation (2/18/2009)
Architecture Capabilities • Basic Capabilities - Defined roles & responsibilities per layer with defined interfaces to enable upgrades - Interfaces that meet open standards to facilitate Third Party Hardware & Software Integration - Allow for vehicle unique functions/electronic but required justifications and allocate costs • Advanced Capabilities - Hot Swap & Dynamic Upgrades - Integrated System Health Management (ISHM) - Reconfigurable Computing - Abnormal Situation Management - Dynamic Commissioning 21 LSS Avionics Concept Study – Final Presentation (2/18/2009)
