The HYPSO-2 mission is the follow-up for the HYPSO-1 satellite that was launched in January 2022. In addition to collecting hyperspectral data across the world, HYPSO-2 will have an on-board SDR used for frequency monitoring, channel measurements and communication experiments (communication between remote sensor systems and the satellite). The SDR platform is selected and partially integrated into the HYPSO software architecture. This project will focus on developing the mission and operationalizing the payload with a focus on channel characterization, including both on-orbit interference measuring and the channel between the satellite and terminals on the ground.  

HYPSO-2 will feature a Totem SDR from Alen Space, Vigo, Spain. This platform is based on the Zync 7030 platform from Xilinx, featuring two ARM core processors (running Linux) and one FPGA for hardware accelerated applications. 

The student should develop the mission and develop SDR applications for channel characterization (interference, propagation). Measurements already performed show a strong interference environment on-orbit, most likely due to space tracking radar systems. The task encompasses developing and testing measurement algorithms, as well as developing mitigation techniques to ensure highest possible throughput. Also, the student can focus on developing measurement strategies (and test those) for characterizing the propagation channel between the satellite and terminals on ground.  

Useful skillset for the student(s): The student should have some background and interest in radio/satellite communication. Knowledge about programming (C/Python/ GnuRadio) is useful, or a desire to learn. We use git and several tools from GitHub to organize our work.  

Example of tasks: Development of SDR applications for recording and analyzing interference measurements. Development of SDR applications for channel propagation measurements. Testing of algorithms in simulations and in the lab setup. Testing algorithms using the LUME-1 satellite (from UVigo) may be possible.   

What we offer: All students working with the HYPSO projects within the SmallSatLab will be part of a multi-disciplinary team, consisting of 20-30 students on BSc, MSc, PhD level. We have a well-equipped lab and the tools are available from the start of the project.
