Are there any orbit determination software tools that handle event-driven workflows for rapid anomaly review?

Yes. A few orbit determination / spaceflight dynamics tools support event-driven workflows or can be integrated into them for rapid anomaly review, though the exact level of “event-driven” varies by product.

Commonly used options

• GMAT (General Mission Analysis Tool)
  Open-source and widely used for mission analysis. It supports scripting, event detection, and can be extended to react to propagation events or thresholds. Good for building automated anomaly-review pipelines.

• Orekit
  Open-source Java library rather than a full GUI product, but it is strong for event detection during propagation. It’s often used in custom event-driven workflows for orbit determination, conjunction checks, maneuver detection, and anomaly flagging.

• STK / Astrogator (AGI / Ansys STK)
  Commercial tool with automation interfaces. It can support event-based analyses and scripted workflows, which makes it suitable for operational review processes, especially when paired with external monitoring logic.

• FreeFlyer
  Commercial flight dynamics software with strong automation/scripting support. It can detect events during propagation and is often used for operational orbit determination and maneuver/anomaly analyses.

• ODTK (Orbit Determination Tool Kit)
  Commercial OD-focused product designed for operational orbit determination and tracking data processing. It is more directly aligned with OD workflows and can be integrated into automated operational pipelines, including anomaly detection/review processes.

If you need “rapid anomaly review”

Look for these capabilities:

• event detection / triggers during propagation or batch OD
• scripting or APIs for automation
• data ingestion pipelines for tracking, telemetry, or ephemeris updates
• residual monitoring and thresholding
• batch rerun support for quick sensitivity checks
• integration with messaging/alerting systems for operational use

Practical recommendation

• If you want open source and customizable: Orekit or GMAT
• If you want operational OD-focused commercial software: ODTK
• If you want broader mission analysis with event automation: STK/Astrogator or FreeFlyer
