ObsSIM Space Scenario Designer enables test designers to construct custom scenarios for test, training, and exercise events. ObsSIM’s library of realistic, physics-driven space events can be added and combined to create a unique timeline that will test the mettle of your team and your automated systems. ObsSIM layers high-fidelity noise on top of truth models to create realistic data indistinguishable from real telemetry feeds.
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, allow your test designers to construct any scenario that today’s congested and contested space environment could throw at you.

Empower your test, training, and exercise designers with diverse, realistic training data
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.
Realistic, physics-driven space events and observations
ObsSIM’s space event models include perigee raises, inclination changes, station keeps, GEO node relocations, Rendezvous and Proximity Operations (RPOs), conjunctions, intercepts, launches, and breakups.
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.
ObsSIM produces physics-based observation data powered by our FreeFlyer astrodynamics engine.
