Overview• Harris’ SmallSat Enterprise:
• High performance payloads and lightweight
electronics
• Affordable access to satellite intelligence
• Collaboration with Virginia Tech to expand on
small-sat infrastructure and communication
• Small satellite modeling platform:• High fidelity
• Tailorable framework to a spacecraft bus
• Ground station: command/telemetry processing
• Develop towards a constellation
• Software integration:• Robust interface of tools for modeling/simulation
• OS/COMET, STK and MATLAB
• Support generic bus and payload systems
• Apply towards coverage optimizationhttps://www.harris.com/solution/oscomet

Interface between OS/COMET and STK/MATLAB simulation platform
Harris’ OS/COMET
• A database-driven system:• Supports spacecraft, constellations and
ground systems
• Configurable to any concept of operations
• A telemetry, tracking and command solution:• Robust and open API interfaces allow for
system expansions
• Features to address ground station
functionality
• Simulation capabilities
• Example applications:• NASA’s Orion vehicle
• Iridium constellation

Current Progress
• Started building the system model: • Spacecraft subsystem definitions
• SysML models
• Started activity/sequence diagram
interactions:• Bus structure interactions
• Communication model interactions

Interface between OS/COMET and STK/MATLAB simulation platform
Future Work
• Finish activity/sequence diagram interactions
• Develop preliminary models based on definitions
• Develop preliminary interface:• STK and OS/COMET
• Investigate how to integrate MATLAB models with
STK simulations. More convenient than JAVA for
modeling.
Possible Issues
• Frameworks compatibility• OS/COMET runs only on Linux
• STK engine uses JAVA API on Linux
• MATLAB and STK compatibility on Linux
• Limited support on integration of software
Proposed Integration model
