SOLIS

Model and simulate spacecraft and their subsystems

A complete spacecraft simulation environment in STK.
Rapidly evaluate system trade-offs and ensure that spacecraft capabilities
and constraints are considered early and satisfied at all times.

Configurable

Easily configure for nearly any spacecraft
design; providing rapid access to
high-fidelity simulation and analysis.

Powerful

Powered by MAX and ODySSy, SOLIS users
interact with real high-heritage Flight Software,
resulting in a true "simulate like you fly"
experience throughout the entire life cycle.

Versatile

Whether you're exploring spacecraft
design in Concept Development or testing
a new Ground System for Operations,
SOLIS can help.

Integrated

As an integrated tool with STK, SOLIS
provides a common place for spacecraft
engineers to focus on overall
mission success.
