This demo shows real-time thermal analysis of a CubeSat in low Earth orbit. The 3D model displays physics-predicted temperature distribution across every surface — solar panels, body panels, radiators, antenna, and payload bay.

Drag the orbital parameter sliders to change altitude, sun angle (beta), internal power dissipation, and orbit position. Each change instantly recomputes the full thermal energy balance — solar heating, Earth IR, albedo, internal dissipation, and radiative cooling.

Select a preset scenario to see characteristic thermal cases: dawn-dusk sun-synchronous (always sunlit), ISS orbit (typical eclipse cycling), high beta angle (thermal stress), or deep eclipse (cold case).

Component Temperatures on the right show predicted temperatures for each subsystem with thermal margins against operational limits.

Traditional satellite thermal analysis (Thermal Desktop, ESATAN) takes 4-8 hours per configuration. Niva computes the same multi-physics thermal balance in milliseconds — enabling engineers to explore dozens of orbital scenarios interactively.
