  1. 1. Definition and evaluation of a system for measuring local geomagnetic variations : Autonomous station for magnetic measurements

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

    Author : Viktor Olsson; [2023]
    Keywords : Local Geomagnetic Variations; Fluxgate Magnetometer; Space Weather; Solar Wind; Magnetic Measurements; Variometer; Solar Activity.; Lokala geomagnetiska variationer; Fluxgate-Magnetometer; Rymdväder; Solvinden; Magnetiska Mätningar; Variometer; Solaktivitet.;

    Abstract : Earth is under constant influence of the Sun and phenomena driven by the solar wind that may affect man-made technology. These events are summarized under the concept of space weather. This creates variations in Earth’s magnetic field and nearby space. Space weather can affect power grids, gas pipelines and also have effects on human health. READ MORE

  3. 2. GPS and IMU Sensor Fusion to Improve Velocity Accuracy

    University essay from Uppsala universitet/Institutionen för elektroteknik

    Author : Adam Laurell; Erik Karlsson; Yousuf Naqqar; [2022]
    Keywords : Sensor fusion; GPS navigation; Extended Kalman filter; Control systems; Velocity estimation; Data processing;

    Abstract : The project explores the possibilities on how to improve the accuracy of GPS velocity data by using sensor fusion with an extended Kalman filter. The proposed solution in this project is a sensor fusion between the GPS and IMU of the system, where the extended Kalman filter was used to estimate the velocity from the sensor data. READ MORE

  4. 3. Characterisation of Satellite Onboard Magnetometer for MIST

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

    Author : Marcus Mhanna; [2022]
    Keywords : Magnetometer calibration; Ellipsoid Fitting; Helmholtz coil;

    Abstract : The most common equipment used for attitude determination in small satellites are magnetometers. However, using magnetometers gives rise to many challenges. One of these challenges is the calibration of the magnetometer. Magnetometer calibration takes many factors into account. READ MORE

  5. 4. FORESAIL-2 AOCS Trade Studies and Design

    University essay from Luleå tekniska universitet/Institutionen för system- och rymdteknik

    Author : Guillaume Le Bonhomme; [2020]
    Keywords : space engineering; CubeSat; ADCS; AOCS; spacecraft subystems; nanosatellite;

    Abstract : This thesis aims to design a reliable CubeSat platform, including the avionic subsystems that can sustain a high radiation environment for a mission having a lifetime of at least six months. The science instruments put stringent requirements on the platform to achieve and maintain the desired spin rate. READ MORE

  6. 5. Robust Drone Mission in the Arctic

    University essay from Uppsala universitet/Signaler och system

    Author : Elvira Brenner; Oscar Hultmar; [2020]
    Keywords : ;

    Abstract : During environmental research projects in the Arctic region AFRY has come across an unproportionally high number of cases where the navigation of drones have not worked as intended, compared to other regions. The main objective of this thesis is to investigate the cause of these navigational problems and determine the main cause. READ MORE
