Timeline Management Tool

The TMT is a web-based timeline tool designed for management and planning of ground commanded spacecraft activities during spacecraft mission operations.

Some key primary functions include:

  • Stored command planning
  • Mission timeline assembly, maintenance,
    management, and display
  • Integrated timeline configuration management
  • Generation of error-free ITOS command pages
  • Pass/command tracking

TMT has successfully supported on-orbit operations for the Fermi, DSCOVR, Raven, JPSS-01 and JPSS-02 missions, STPSat-6 and Landsat-9 and will be utilized for on-orbit commissioning and normal operations of the PACE mission.
