1. 1. 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.

3. 2. GPS-Free UAV Geo-Localization Using a Reference 3D Database

   University essay from Linköpings universitet/Institutionen för systemteknik

   Author : Justus Karlsson; [2022]
   Keywords : Deep Learning; Machine Learning; ML; AI; UAV; GPS-Free; CNN; 3D CNN; GCNN; 3D Database; geolocalization; geo-localization; georegistration; Hidden Markov Model; HMM; satellite; satellite database; Batch-Hard; triplet loss; PyTorch Geometric;

   Abstract : The goal of this thesis has been global geolocalization using only visual input and a 3D database for reference. In recent years Convolutional Neural Networks (CNNs) have seen huge success in the task of classifying images. The flattened tensors at the final layers of a CNN can be viewed as vectors describing different input image features. READ MORE

4. 3. Enhancing GPR Measurements using Real Time Kinematics and LiDAR Mapping

   University essay from Umeå universitet/Institutionen för fysik

   Author : Christoffer Elebro; [2022]
   Keywords : GPS; GNSS; RTK; Lidar; 3D-mapping;

   Abstract : A Ground Penetrating Radar (GPR) is a non-invasive measurement tool to locate objects in the subsurface. The GPR transmits electromagnetic waves into the ground and records the waves reflected from surface interfaces of different materials. READ MORE

5. 4. Localization For AutonomousDriving using Statistical Filtering : A GPS aided navigation approach with EKF and UKF

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

   Author : Devrat Singh; [2022]
   Keywords : Land Vehicle Localization; Sensor Fusion; GNSS-INS Fusion; UKF; EKF;

   Abstract : A critical requirement for safe autonomous driving is to have an accurate state estimate of thevehicle. One of the most ubiquitous yet reliable ways for this task is through the integrationof the onboard Inertial Navigation System (INS) and the Global Navigation Satellite System(GNSS). READ MORE

6. 5. Analysing space dependencies - Methods and factors for method development

   University essay from Lunds universitet/Riskhantering (CI); Lunds universitet/Avdelningen för Riskhantering och Samhällssäkerhet

   Author : Theodor de Sousa; [2022]
   Keywords : Vital societal functions; critical infrastructure; interdependency; dependency analysis; space services; space infrastructure; GNSS; PNT; ICT; method development; Technology and Engineering;

   Abstract : Vital societal functions and critical infrastructure rely to an increasing extent on services from space, such as navigation and positioning systems, timekeeping, and communications. However, understanding of space service dependencies is low among practitioners and society at large, with research on societal space dependency being limited as well. READ MORE
