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



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

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
