Light Fidelity (LiFi) for intra-satellite communication offers significant advantages, including flexible Assembly, Integration and Testing Phase (AIT) and reduced harness complexity. This paper presents a simulation framework for light propagation, primarily aimed at optimizing positioning, spatial structures, and system parameters for intra-satellite LiFi architectures. Initial simulations included generic scenarios such as obstacle simulation and transmitter–receiver alignment, followed by integration of a complete 3D CubeSat model. Results demonstrate the framework’s capability to support the optimization and visualization of optical communication structures, enabling virtual analysis that complements physical test setups in early development stages. The framework has been extended to incorporate diffuse reflection and simple wavelength-independent refraction, while supporting iterative reuse of simulation results and channel characteristics enabling iterative transmitter and receiver placement optimization.
