1. Ensuring safe docking maneuvers on floating platform using Nonlinear Model Predictive Control (NMPC)
University essay from Luleå tekniska universitet/Institutionen för system- och rymdteknikAbstract : Docking maneuvers are a relevant part of the modern space mission, requiring precision and safety to ensure the success of the overall mission. This thesis proposes using a non-linear Model Predictive Control (MPC) as a controller with various constraints to ensure safe docking maneuvers for a satellite. READ MORE

2. Real-Time Navigation for Swarms of Synthetic Aperture Radar (SAR) Satellites
University essay from Luleå tekniska universitet/RymdteknikAbstract : The pursuit of precision and flexibility in satellite missions has led to an increased number of formation flying missions being developed. These systems consist of multiple satellites flying at close distances (from a few kilometres to a few meters) to achieve common objectives. READ MORE

3. Antarctic Subglacial Lakes as Environmental Analogues for Possible Hidden Biospheres on the Moons Europa and Enceladus
University essay from Uppsala universitet/Institutionen för geovetenskaperAbstract : The evolving science of astrobiology for the search for life beyond Earth has put focus on the possibility of subsurface bodies of liquid water beneath the surface of icy moons within our Solar System. Specifically, the Jovian moon of Europa and the Saturnian moon of Enceladus show telling characteristics of endogenous heating through their complex tidal resonances with their parent planets – suggesting the presence of oceans of liquid water and therefore a potential for astrobiology.

4. Evaluation of Geopositioning Using Frequency Responses From Radio Propagation Measurements
University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)Abstract : Satellite reliant navigation systems may struggle in urban environments as tall buildings mayobstruct necessary direct lines of sight with satellites. There have been multiple studiesexamining how WIFI fingerprinting may be used for indoor positioning. READ MORE

5. Real Time Navigation Algorithms for LEO Small Satellites using COTS GNSS
University essay from KTH/Lantmäteri – fastighetsvetenskap och geodesiAbstract : Many satellites in LEO use a GNSS-based navigation system, taking advantage of the GNSS constellations in MEO to enhance navigation capabilities. The thesis work focused on developing the software enabling GNSS-based navigation for Hemeria's future small satellites operating in LEO. READ MORE
