Mission Planning and Scheduling
Omitron offers both mission planning services and tools for space missions. Mission planning is the realm where disparate groups such as end customers, spacecraft bus and instrument vendors, and ground support personnel must come together to both meet their individual needs and realize mission objectives. All of this must be done within a myriad of constraints imposed by flight and ground segment capabilities, temporal limitations, and the laws of physics. Omitron engineers have extensive experience in bringing order and efficiency to the mission planning process.

Omitron's mission planners:

  • Provide dedicated attention to mission planning
  • Identify and track activities and constraints
  • Create and maintain the mission timeline
  • Identify and work to resolve issues early to reduce mission impact
  • Provide on-line support during critical launch and early orbit activities.

Omitron mission planners proactively interface with all of the necessary parties to develop and maintain the mission timeline. Early attention to the development of such timelines often reveals constraints and conflicts which must be managed. Omitron mission planners work to uncover issues in the evolving timelines and work aggressively to resolve them early to minimize cost and performance impacts.

The Omitron mission planning process includes organizing dedicated working groups to provide focus on the mission timeline. Mission planners interface with all participating groups to identify activities and their associated constraints. They participate in mission simulations and rehearsals to aid in the coordination and execution of activities and ensure that the timeline is adequate under real conditions within the stress of a live environment.

During the Launch and Early Orbit (L&EO) phase, Omitron mission planners react quickly and accurately to ever changing circumstances. Events such as launch slips, missed passes, and other contingencies often have severe impacts on the mission timeline. Reactions to such events typically require a timely re-plan of future events within the confines of all known constraints, a signature approval process, and re-scheduling of pass support services.

To meet the mission planning needs in both the pre-launch and real-time environments, Omitron developed the Timeline Management Tool (TMT). The TMT provides features such as web-based timeline communication, timeline configuration management, remote signature approval, modular timeline construction, pass-page generation, activity completion tracking, real-time command page generation, time-slip capabilities, and many more.

Omitron also maintains expertise in resource de-confliction and schedule optimization tools to help resolve complex scheduling problems and promote efficient use of assets to maximize the achievement of mission goals. Omitron mission planners are fully competent in utilization of the Omitron-enhanced FDS mission planning suite to assess the impact of satellite attitude maneuvers in terms of operational constraints, and to manage and optimize contact scheduling with the TDRS network via the SWSI/SNAS system and with GN sites via the USN NMC.

Omitron mission planners have provided mission planning services and tools to the Swift, Fermi, Hubble Space Telescope, and STS missions, among others.

Highlights of Recent Mission Planning Work

Fermi (GLAST) Omitron lead the development of the mission timeline for the launch, activation, and early orbit test phases. During early orbit operations, Omitron personnel played a central role in maneuver planning, spacecraft test and activity scheduling, and contact scheduling. In the normal operations phase, Omitron flight operations personnel are intimately involved in the day-to-day planning of all satellite activities.

Omitron developed several planning and scheduling tools for the Fermi mission including the TMT for mission timeline management and the FDS for contact scheduling. Omitron customized the MPS command sequence builder for use on Fermi and played a key role in the development and customization of the TAKO science planning system.

Swift Omitron played a significant role in the development of the mission timeline for the launch, activation, and early orbit checkout phases. During early orbit operations, Omitron personnel played a central role in spacecraft test and activity scheduling as well as contact scheduling. Omitron flight operations personnel are intimately involved in the day-to-day planning of all satellite activities.

Omitron customized the MPS command sequence builder for use on Swift and played a key role in the development/customization of the TAKO science planning system.
