New AI Software Completely Replaces Legacy ESD 2.7 System Around the Globe, Greatly Increasing Readiness of Missions and Operations that Rely on the Satellite Control Network (SCN)

SAN MATEO, Calif., Jan. 8, 2026 /PRNewswire-PRWeb/ -- Stottler Henke's MIDAS Automated Resource Scheduler (MARS)/Automated Scheduler Tool (AST) system has achieved a significant milestone by successfully assuming live operational control from the legacy Electronic Schedule Dissemination 2.7 (ESD 2.7) system, which has been in service since 1992. The ESD platform, a DOS-based "interim" solution, has served as the operational backbone for Satellite Control Network (SCN) operations for over three decades but has been deactivated.

The MARS system is used by U.S. Space Force Satellite Schedulers to ingest orbital information as well as requests from users, provide human schedulers with a highly flexible interface to optimize the schedule, and distribute the information to Satellite Flyers, the end users, and the automated antennas globally. Not only do these capabilities enhance the SCN's effectiveness, but also its responsiveness to changing demands and resilience to adverse events.

MARS automatically generates 24-hour schedules within minutes for hundreds of satellites and thousands of tasks across multiple, competing constellations and Satellite Operations Centers (SOCs), balancing both hard and soft scheduling constraints. MARS also supports real-time launches, conflict checking, schedule changes, and rapid response to in-space emergencies or equipment failures, while enabling multiple distributed users to collaborate simultaneously.

In addition, the system is built on Stottler Henke's Aurora scheduling engine that automatically deconflicts the schedule, reducing a human operator's cognitive load by over 90%. The system also includes robust fault-tolerance features such as hot backups, automatic node failover and recovery, data archiving, and detailed activity logging to ensure uninterrupted operations. MARS also provides tools for schedule quality assessment, radio-frequency-interference (RFI) investigation, and detailed task editing and communication between users. Together, these capabilities enable MARS to deliver a resilient, automated, and highly responsive scheduling environment for modern satellite control missions.

The transition to MARS/AST as of September 12, 2025, marks a pivotal advancement in modernizing operational infrastructure. Developed to provide enhanced functionality, scalability, and maintainability, MARS/AST establishes a robust foundation for future growth. This milestone opens new opportunities to expand the system's user base and further integrate advanced capabilities to meet evolving space mission requirements.

This accomplishment reflects the dedication and collaboration of all personnel involved in the development, testing, and deployment of MARS/AST. Stottler Henke and the entire project team have ensured a seamless transition, positioning the organization for continued operational excellence and innovation.

"The acquisition and fielding of the Advanced Scheduling Tool directly elevated the Satellite Control Network satellite contact process to the level required for evolving USSF telemetry, tracking, and commanding needs," says Lt. Col. Jean A. Purgason, USSF, Commander, 22nd Space Operations Squadron. "This innovative system overhaul delivered seamless operations on current industry standards, enhanced cyber awareness, and increased Satellite Control resiliency for the network's 18 antennas and over 165,000 annual satellite contacts, the first such upgrade in over 33 years," continues Lt. Col. Purgason.
