| Milestone | Date | Accomplishment and Impact |
CMMI Appraisal | Sept. 2014 | Accomplishments: Participated in GSFC center-wide CMMI appraisal (level 2). Evaluated for project monitoring and control. Impact: Tweaked some process areas providing more efficient development. Well positioned for process requirements in GTDS replacement effort. Supported center level accreditation. |
Release R2014a | 2013 | Accomplishments: Release new version of GMAT. First release after certification using new development process. Impact: Useful new features including attitude models, state representations. First release with features co-developed by external organization sharing costs. |
ACE Operational Certification | 2014 | Accomplishments: Successfully passed operational readiness review for ACE. Impact: Demonstrated GMAT is flight quality software setting the stage for broader adoption by flight projects. Since the qualification, TESS has adopted GMAT as the primary flight dynamics tool, and OSIRIS has adopted GMAT for launch window analysis and will use GMAT for validation of other tools to be performed during operations. |
GMAT Training | 2013 | Accomplishments: Provided training to 595 and FDF engineers. Impact: Prepared engineering staff for large scale use of GMAT across multiple flight projects. |
Production Release | 2013 | Accomplishments: Production release: GMAT R2013a. GMAT is no longer beta software. Rigorously tested. Wrote approximately 5000 new script regression tests. Grew GUI regression tests to approximately 3000 tests, fixed hundreds of bugs. Completed 600 pages of user documentation with tutorials and reference material. Impact: Investments in GMAT are ready for broad application across flight projects. Models are validated for other development areas such as GTDS replacement. |
Ops Certification | 2013 | Accomplishments: Completed implementation and testing of all new features required to support ACE maneuver planning. Excellent agreement between GMAT and FreeFlyer. Impact: GMAT is ready for non-interfering shadow ops and soon for operational use. After ORR in Fall of 2013, we can begin cost sharing across flight projects. Until this point, flight projects knew they would have to switch to STK or FreeFlyer so they would not invest in GMAT. |
NPR Compliance | 2013 | Accomplishments: Updated documentation and processes for NPR compliance. Impact: Required by the agency. Well positioned for other development areas such as GTDS replacement. |
