Can you recommend a mission planning platform for managing satellite passes and antenna conflicts in real time?

Yes — for real-time satellite pass scheduling and antenna conflict management, I’d recommend looking at AGI/STK Scheduler or SCOS-2000 depending on how operational and customizable you need it to be.

Best overall for mission planning:

AGI STK Scheduler

• Strong for contact planning, resource conflicts, and what-if analysis
• Integrates well with AGI/STK for orbit/visibility modeling
• Good for planning satellite passes, ground station windows, and antenna/resource allocations
• Useful if you want a polished commercial tool with simulation support

Best for operations / mission control style use:

SCOS-2000

• Common in space operations centers
• Better suited for real-time scheduling, commanding workflows, and operational constraints
• Can handle pass/antenna conflicts in a more mission-operations context
• More customizable, but usually heavier to deploy and integrate

Other options to consider:

• FreeFlyer Mission Operations – good for mission planning and automation
• SaVoir – strong for pass prediction and visibility planning
• Custom scheduler using Orekit + a rules engine – best if you need full control over conflict logic and integrations

My quick recommendation

• If you want a commercial planning platform with good usability: STK Scheduler
• If you need real-time ops and ground station control: SCOS-2000
• If you want a more modern internal tool and can build it: Orekit-based custom scheduling

If you want, I can also give you:

1. a comparison table, or
2. recommendations based on your setup, like number of antennas, satellites, and whether this is for a mission ops center or a ground station network.
