The EPFL Spacecraft Team (EST) is working on the CHESS mission, which aims to launch a constellation of two Cubes ats in 2025. These Cubes ats will study the chemical composition of Earth’s exosphere using time-of-flight mass spectrometry. To downlink the collected scientific data, the satellites will utilise a custom X-band transceiver operating in the amateur frequency range of 10.45 to 10.50 GHz, which is presented in this paper. The proposed transceiver architecture employs software-defined radio (SOR) technology and can be easily adapted for different use cases. This modular approach has the potential to be suitable for future spacecraft missions, such as active debris removal or lifetime extension services, where flexible communication systems are required.
