1. Design and Implementation of a Rocket Launcher Hybrid Navigation
Master-uppsats, KTH/Lättkonstruktioner, marina system, flyg- och rymdteknik, rörelsemekanikSammanfattning : 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.

2. Localization For AutonomousDriving using Statistical Filtering : A GPS aided navigation approach with EKF and UKF
Master-uppsats, KTH/Skolan för elektroteknik och datavetenskap (EECS)Sammanfattning : 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). LÄS MER
3. Markering av dolda objekt på väg genom användning av förstärkt verklighet.
Kandidat-uppsats, Högskolan i Gävle/DatavetenskapSammanfattning : Enligt en rapport från trafikverket förekommer kollisioner vid väghållningsarbeten mellan väghållningsfordon och objekt täckta av väglag. Dessa trafikolyckor kan leda till personskador, skador på infrastruktur och skador på de inblandade väghållnings-fordonen. LÄS MER
4. GPS-oscillation-robust Localization and Visionaided Odometry Estimation
Master-uppsats, KTH/Maskinkonstruktion (Inst.)Sammanfattning : GPS/IMU integrated systems are commonly used for vehicle navigation. The algorithm for this coupled system is normally based on Kalman filter. However, oscillated GPS measurements in the urban environment can lead to localization divergence easily. LÄS MER
5. Improved Situational Awareness of Heavy Machinery Operators in Low Visibility Conditions
Master-uppsats, KTH/Maskinkonstruktion (Inst.)Sammanfattning : This thesis studies potential solutions to improve the situational awareness of operators of heavy machinery in low visibility conditions caused by snow, heavy rain or fog. Sensors and techniques intended to provide situational awareness for vehicles have been studied in previous research, but these studies have not covered the robustness of the sensor platform to fog, heavy rain or snow.
