Multimission Ground Systems & Services MOS 2.0: A View of the Next Generation in Mission Operations Systems Duane L. Bindschadler, Carole A. Boyles, Carlos Carrion, and Chris L. Delp Jet Propulsion Laboratory, California Inst. Of Technology Pasadena, CA, U.S.A.

Multimission Ground Systems & Services Outline Background Motivation –Why architect and model Example – Process identification & modeling Example – Model-based approach to scenarios Future Work Improving Space Operations WorkshopBindschadler – 2

Multimission Ground Systems & Services Background Multimission Operations –A multi-mission operations capability is engineered so as to require minimal work effort to adapt across the defined range of customers (deep-space robotic missions). This includes consideration across the lifecycle of the customer and of the capability itself. Multiple success 1990 – early 2000s –Range of applicable missions limited –Faster-better-cheaper (not maintainable long term) Competitive pressures motivate search for more efficient methods Operations Revitalization Initiative will help to create those methods –Architected, model-based MOS 2.0 Improving Space Operations WorkshopBindschadler – 3

Multimission Ground Systems & Services Improving Space Operations WorkshopBindschadler – 5 Why Architect & Model? Systems and enterprises have architectures, whether or not they are explicitly documented and maintained Architectural approaches identify and address stakeholder concerns –Enterprise-wide to very fine-grained –Distinct viewpoints address concerns Model-based approaches enable –More formal, explicit specification –Management of complexity –More evolvable systems

Multimission Ground Systems & Services Improving Space Operations WorkshopBindschadler – 6 Why Architect & Model? Right" time to do it. –MBSE/architecture initiatives and interest taking hold at JPL and across NASA –Standards are maturing –Modeling tools are becoming able to support formal, rigorous description of highly complex systems –Piece-meal approaches have not been as effective as anticipated

Multimission Ground Systems & Services Advantages Less work effort in documenting –Less time in Word or Powerpoint Increased focus on engineering design work Improved ability to make accurate predictions about the impact of changes Ability to model even complex processes Clearer path for automation Improving Space Operations WorkshopBindschadler – 7

Documenting Science Goals Identifying Mission Operations Phases Identify Flight System and Ground System Constraints Baselines Science and Mission Capabilities Used in Support of Proposal and Cost efforts Preliminary Design and Technology Completion Phase

Multimission Ground Systems & Services Improving Space Operations WorkshopBindschadler – 13 Scenario Process

Multimission Ground Systems & Services Improving Space Operations WorkshopBindschadler – 14 Managing the Scenario Process-- The scenario tool was designed with the intent to support the process owner in facilitating the operations scenario process. The attributes specific to managing the Scenario Process are: –Status –Automatic –Electronic Signatures –Action Items –Revision Capability –Copy Capability –Attachments –Search capability on any field Scenario Tool Attributes

Multimission Ground Systems & Services Improving Space Operations WorkshopBindschadler – 15 Scenario Tool Attributes Scenario Accessibility -- Scenarios are maintained in a web accessible environment that provides a structured set of scenario fields. Online Collaboration -- The scenario tool allows for collaboration through the use of a comments field. The comment is instantly visible.

Multimission Ground Systems & Services Improving Space Operations WorkshopBindschadler – 16 Scenario Tool Attributes Interleaving Requirements -- The scenario tool has the ability to embed requirements into the scenario description. Linking to Interfaces -- Operational Interface Agreements (OIAs) are created to communicate agreements between teams. With the Advanced Multi-Mission Operations System (AMMOS) at JPL, the OIAs are maintained in a web based tool similar to the scenario tool.

Multimission Ground Systems & Services Improving Space Operations WorkshopBindschadler – 18 Scenario Tool Attributes Copy a Scenario – The tool allows key fields of a scenario be copied and stored for use on other missions. Revise a Scenario – Revision Capability helps supports the lifecycle of a scenario by finalizing the scenario at each key decision point in the lifecycle then assigning a revision naming convention and moving forward key fields.

Multimission Ground Systems & Services Next Steps Full lifecycle architecture for MOS 2.0 –Development (~Phase A – D) –Deployment (transition from Development to Ops) –Operations (Phase E) –Continuous improvement and maintenance Flow-down of system level to development of composable services –Mission Planning & Sequencing –Mission Control –Other services follow Coordinate & unify with software-focused architectural effort Improving Space Operations WorkshopBindschadler – 19
