1. 1. Using GIS and satellite data to assess access of green area for children living in growing cities

   University essay from Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskap

   Author : Rebecca Borg; [2024]
   Keywords : Geography; GIS; Geographical Information System; Urban green space; children; schools; Malmö; Earth and Environmental Sciences;

   Abstract : Urban green space (UGS) refers to open spaces within an urban context that are filled with greenery and nature. These can range from very small vegetation to expansive park areas. The common denominator is that they have proven to be beneficial for human health and well-being. Access to green spaces is also important for children. READ MORE

3. 2. Real-Time Navigation for Swarms of Synthetic Aperture Radar (SAR) Satellites

   University essay from Luleå tekniska universitet/Rymdteknik

   Author : Antoni Eritja Olivella; [2024]
   Keywords : SAR; Real-time orbit determination; Real-time baseline determination; swarms; satellite; formation flying;

   Abstract : 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

4. 3. LEO Satellite Connectivity for flying vehicles

   University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)

   Author : Jinxuan Chen; [2023]
   Keywords : LEO satellite network; satellite connectivity strategy; Nash-SAC; flying vehicles; LEO:s satellitnät; Strategi för satellitanslutning; Nash-SAC; flygande fordon;

   Abstract : Compared with the terrestrial network (TN), which can only support limited covered areas, satellite communication (SC) can provide global coverage and high survivability in case of an emergency like an earthquake. Especially low-earth orbit (LEO) satellites, as a promising technology, which is integral to achieving the goal of global seamless coverage and reliable communication, catering to 6G’s communication requirements.

5. 4. Monitoring deforestation in the Serranía de Chiribiquete in northern Colombian Amazon using time series analysis of satellite data

   University essay from Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskap

   Author : Yuyang Qian; [2023]
   Keywords : Physical Geography and Ecosystem analysis; CCDC; Forest loss; Landsat; Sentinel-1; Change detection; NNP; FARC; Earth and Environmental Sciences;

   Abstract : Deforestation monitoring is of significant importance for the ecosystem, climate change,and policy-making. The availability of optical and synthetic aperture radar (SAR) satellite remote sensing images, along with the development of time series change detection methods, has contributed to the increasing popularity of time series analysis in forest disturbance monitoring.

6. 5. Design and Implementation of a Rocket Launcher Hybrid Navigation

   University essay from KTH/Lättkonstruktioner, marina system, flyg- och rymdteknik, rörelsemekanik

   Author : Omar Ugolini; [2023]
   Keywords : launch vehicle navigation; delayed Kalman filter; strapdown; navigering av bärraketer; fördröjt Kalman-filter; strapdown;

   Abstract : Rocket Factory Augsburg (RFA) a German New Space Startup is developing a three-stage rocket launcher aiming at LEO/SSO orbits. A fundamental responsibility of the GNC team is the development of the rocket navigation algorithm to estimate the attitude, position, and velocity allowing the guidance and control loops to autonomously steer the rocket.
