Position title Description Keywords Recommended studies
S-Band positioning upgrades The positioning control of a satellite ground station allows for the uninterrupted pointing to the satellite during the transit of the satellite over the ground station. This allows for the maximum directivity of the antenna to be achieved, improving the communications link. Smooth motion of the antenna, and precise determination of the current Elevation and Azimuth are key to provide small movement jitter, and consequently interruptions in communications. Developments towards a smoother movement and absolute encoders for the S-Band and UHF ground stations will be carried out.

Advanced TinyGS - an open ground station for LoRa communications Upgrade of an open source ground station for PocketQubes communicating using LoRa. The upgrade will include a new 2x2 antenna array, the positioner, and a control software. Positioning, Antennas, Electronics, Ground Station Telecommunications, Electronics, Aerospace
Frequency-diversity systems for robust ionospheric propagation Ionospheric scintillation are fast intensity and phase fluctuations of the signals when transversing the ionosphere. These effects are very important at equatorial and polar latitudes and difficult radiocommunications, notably at VHF and UHF bands. These fluctuations are partially correlated in space and frequency, so they can be mitigated by using multiple antennas, or multiple frequency bands. In this study we will analyze the ionospheric propagation channel and derive optimum band selection algorithms for robust transionospheric propagation.

3Cat-8 Communications software: LoRa ISL In a Federated Satellite System (FSS) unused resources are shared among different partners. Initially planned for the FSSCat mission, an FSS experiment will be performed between 3Cat-8 and two PocketQubes. They will be inter-connected through LoRa IoT communications. In this work, previous developments of LoRa communications will be implemented in the 3Cat-8 spacecraft. Software, Communications, Internet of Things Telecommunications, Electronics
3Cat-8 Camera Control The polarimetric and multi-spectral aurora imager will be formed by a Bayern-type multi-spetral camera with a rotating polarizer in front of it located in one of the two "tuna cans". This TFG/TFM will focus in the control of such rotation motor, so that images are acquired when the polarizer is at particular angles, so that the first three Stokes elements can be properly computed.

FPGA-based miniaturized reflectometer for Pocketqubes GNSS-Reflectometry is a remote sensing technique that acquires a known signal after its reflection, obtaining important geophysical measurements. New developments of Pocketqube-based Earth Observation payloads are underway to provide a low-cost efficient implementation of a reflectometer with open source FPGAs. Future PoCat's will include new GNSS-Reflectometry Earth Observation payloads, in which the lab has a long-lasting experience and demonstrated flight heritage. The next challenge is to implement such systems in a 2P PocketQube. FPGA, Linux, RF, Signal Processing Telecommunications, Electronics, Aerospace
