Worked on enhancing the realism of spacecraft simulations in the Project-5-Space-Craft repository by developing a backend feature for high-fidelity telemetry data generation. Leveraging C# and backend development skills, implemented updates to the TelemetryService to produce varied and realistic readings for position, temperature, radiation, and velocity, with a focus on accurate unit representation by updating ToString methods to display velocity in kilometers per second. Introduced random value generation to simulate authentic payload data, improving the quality and reliability of test scenarios. This work addressed the need for more accurate data simulation, supporting better validation of downstream systems without reported bugs.
