In this paper, a LiFi-transceiver suitable for Telemetry and Telecommand (TMTC) intra-satellite communication is developed and evaluated. The focus of the implementation is on miniaturization and energy-efficiency. First test results with a simple Transimpedance-Amplifier and an investigation of the achievable eff. data rate depending on different distances and Error-Correcting-Codes and the energy-consumption of the developed transceiver are presented. The results show that the LiFi-transceiver achieves a payload data rate of 77.6 kbit/s with Error-Correcting-Code protection and thus can be used for a reliable TMTC communication within the satellite bus.en2673-459120251Multidisciplinary Digital Publishing Institutehttps://creativecommons.org/licenses/by/4.0/CubeSat | intra-satellite communication | Light Fidelity (LiFi) | Optical Wireless Communication (OWC) | Telemetry and Telecommand (TMTC) | Transimpedance-Amplifier (TIA)Technology::629: Other BranchesTechnology::621: Applied Physics::621.3: Electrical Engineering, Electronic Engineering::621.38: Electronics, Communications EngineeringJournal Articlehttps://doi.org/10.15480/882.1540610.3390/engproc202509001610.15480/882.15406Journal Article
