Code 583 Technologies and Products

Advanced Spacecraft Integration and System Test (ASIST)/Front End Data System (FEDS)

Principal Investigator (PI)

Description and Objectives

• A common Telemetry and Command System for all phases of a life cycle of a mission from Components Development, I & T and Operations.
• Scalable Architecture from a single ASIST workstation to tens of ASIST workstations with each ASIST looking at a different subsystems or doing playbacks.
• Intuitive and user-friendly page development tool.
• Playback capability from archive for anomalies determination.
• Easily adaptable to support multiple missions.

Typical ASIST console with STOL input, event log, procedures, pages & plots

Technical Approach

• Single development tree for multiple missions.
• New capabilities are additive (no loss of old capabilities).
• Robust regression testing for all new releases.
• Open source development environment except for the Graphical User Interface (using Kinesix's SAMMI*)
• CCSDS* compliant (supports SLE*, CFDP*, etc.)
• Standard interfaces (TCP* sockets, GMSEC* bus, etc.)
• * SAMMI: Standards-based, Advanced Man-Machine Interface; CCSDS: Consultative Committee for Space Data Systems; 
     SLE: Space Link Extension; CFDP: CCSDS File Delivery Protocol; TCP: Transmission Control Protocol; 
     GMSEC: Goddard Mission Services Evolution Center; DBMS: Database Management System; ST-5: Space Technology-5; 
     MMS: Magnetospheric MultiScale mission; CFS: Core Flight System

Main Innovation(s)

• Rapid proto-typing with quick turn-around times for database development and testing without a commercial DBMS.
• Constellation support (ST-5*, MMS*)
• Compiled scripting language for faster execution
• Distributed Parallel Commanding
• Parallel execution of multiple procedures

Infusion Potential

• Already integrated with CFS* & GMSEC.
• Used by FSW Branch for S/W develop. & testing.
• Gateway software with most ground stations already developed.
