ObsSIM Space Scenario Designer enables you to construct scenarios for tests, trainings, and exercises. With ObsSIM's library of realistic, physics-driven models, you can design even the most complex launch and on-orbit scenarios. ObsSIM’s data-derived sensor models give you the realistic sensor observations you need to test the mettle of your systems, procedures, and teams.

Your operators need to be ready for anything

ObsSIM helps you train for any scenario. Prepare your operators for the worst days in space with our simple workflows for designing test, training, and exercise scenarios.

Feel confident in your ability to protect your assets

Be ready to put your procedures into practice. ObsSIM's complete library of space events, from launch to re-entry, allows your scenario designers to construct any scenario that today's congested and contested space environment could throw at you.

ObsSIM Launch Features

Simulated observations enable operators to rehearse launch processing

Surface to space modeling

Configure launch site, time, and destination orbit

ObsSIM Maneuvers Features

Deployment of cubesats and other secondary vehicles

Rehearse your observation correlation and new object cataloging procedures

ObsSIM ASATs Features

Enable operators to practice procedures to identify and respond to ASAT threats

Direct ascent and orbital trajectories

Operators learn how to identify and protect the target RSO

Breakups and Collisions Features

Generate simulated observations of debris-generating events

On-orbit explosions, micrometeoroid strikes, and RSO collisions

Enable operators to practice new debris object cataloging procedures

ObsSIM Reentries Features

End of life modeling

Natural decay or planned deorbit

Operators rehearse prediction of entry timing and footprint

Empower your test, training, and exercise designers with realistic training data

With ObsSIM’s interactive views and informative timeline, preview your events, fine tune your plan, then execute the simulation. Publish data in real time or faster-than-real-time. Layer simulated data over live feeds for sim-over-live training.

Realistic, physics-driven space events and sensor observations

ObsSIM’s space event models include DA ASATs, station keepings, GEO drifts, rendezvous and proximity operations (RPOs), close approaches, launches, breakups, and more.

ObsSIM models Resident Space Object (RSO) tasking categories, solar lighting constraints, range constraints, sensor slew rates, and sensor dwell times so our simulated observations reflect realistic collection capabilities.
