Simulate space events for Test, Training, and Exercise (TTX) support.
As space becomes an increasingly dangerous environment for satellites, operators must be ready to detect and respond to potential threats. With Space Event Generator (SEG), you can quickly develop high-fidelity simulations of space events to test detection algorithms, train operators, and perform readiness exercises. SEG can simulate a wide assortment of space events, which describe types of behaviors conducted by satellites. These events can vary from simple maneuvers by single satellites to complex multi-satellite collisions and breakups. Link events together to create a scenario, select trackers and sensor cadences to process it, and produce a realistic set of simulated observations.
SPACE EVENT GENERATOR
Rapid and accurate simulated space events for Test, Training, and Exercise (TTX) support.
SEG allows non-expert operators to quickly develop accurate, physics-based scenarios of common space events, from single object maneuvers to complex, linked, multi-object interactions, using simple, GUI-based operator workflows.
Use cases supported
Key value points
- Doesn’t require operators with extensive astrodynamics expertise to create accurate, realistic space events
- Enables rapid generation of simulated tracking observations and “truth” ephemeris
- Easier to use and more accurate than morphed historical data
Enterprise Workflow
- Copy state data from SSA database for exercise/training
- Build scenario(s) in SEG:
- Define events
- Define sensor cadence
- Run scenario(s) in SEG to create obs
- Use obs in SSS/other for exercise or training (can layover real data if desired)
Core Capabilities
- Time independent. Events and observations can be synchronized to run in current time, or in past or future epochs, and can be combined on a user-defined timeline to generate a complete exercise scenario.
- Robust 3D visualization. A 3D visual interface provides an easy way to visualize the scenario events.
- Accuracy. SEG accounts for space weather effects, sensor performance models (including lighting and elevation constraints), and force models based on orbit class.
- SOA Architecture. SEG’s Service Oriented Architecture with clearly documented API’s enables the use of web services for direct integration with customer architectures or COMSPOC’s SSA Software Suite.
- User workflows. SEG includes a variety of pre-defined event types out of the box and easy to use, operator workflows, enabling rapid scenario creation.

Technical Details
Enterprise architecture
- Multi-user: share scenarios and results across the enterprise via a single, common database
- Security: integrates with enterprise authentication services
- Scalable: supports large scale simulations; scales calculations across compute nodes
- Browser-based UI
Sensor
- Sensor access calculated and visualized in the Scenario view
- Supported sensor types: optical, RADAR, space-based
- User-defined sensor cadences: tracks/day, observations/track, trackers, timestep, and revisit time
Catalog Event
User-defined list of 1 to n (no limit) RSOs propagated over the scenario time span. These background objects provide additional realism and complexity to the simulated scenario.
Maneuvers
- Users can model maneuvers as either impulsive or finite
- Finite maneuvers are modeled using engines with constant thrust and Isp
- Users can define their own engine models or select from those provided
Ephemeris Event
The ephemeris event allows users to directly define a SEG event using externally provided ephemeris. This allows creation of more complex events using external tools such as STK.
Objects
- SEG enables use of real world, SSN catalog objects and simulated, user-defined objects in concert
- This approach supports simulated over live operations
Scenarios
- A container for a collection of events over a span of time
- Users can combine and reuse existing events into different scenarios
Linked Events
- Users can link multiple events without having to manually solve for the intermediate maneuvers
- SEG automatically calculates the requisite maneuvers using Lambert’s solution to link the events
- These orbit transfer maneuvers may be modeled as either impulsive or finite
Outputs
- B3 observations
- Ephemeris
- Can then be fed into a flight dynamics or catalog processing system
- Segment reports
- VDFs for use in STK
