Happy Earth Day from SPEC Innovations! The SPEC Innovations team is doing our part by using Innoslate for environmental systems engineering with the Innoslate project, FireSat. Firesat uses model-based systems engineering and creates a process that uses space satellites to detect forest fires!
We can do this by building fire satellite system requirements documents, and adding relationships such as traced to, verified by, and satisfied by. As we build, we can add in live diagrams directly into our document.
Next we start modeling the process. The Design Reference Mission for FireSAT is similar to other scientific earth observation missions.The normal operations are preceded by a series of spacecraft and payload commissioning steps and followed by disposal at the end of the mission, years in the future. Our systems engineers drag and drop steps, decisions, actors (assets) into the diagram.
We create a concept of operations diagram for the system using an asset diagram and adding images for our asset. This diagram shows the various components and conduits that make up the FireSat system, adding attributes for accurate simulation.
We then use the discrete event simulator to check that our process model executes. Once it executes, we’ll check the variance of the cost, schedule, and performance in the monte-carlo simulator.
Now that we know the process works, we create a test suite and track our test progress. Lastly, we’ll use a Traceability matrix, making sure we use the built-in traceability assist and suspect assist to determine accurate traceability.
By utilizing requirements management, process modeling, asset allocation, cost simulation, testing, and much more, this project shows how systems engineers can prevent damage to the atmosphere and slow climate change! Happy Earth Day from SPEC Innovations!
