  1. 1. Testing for verification and validation of an onboard orbit determination system exploiting GNSS : A nanosatellite application for HERMES-SP

    Master-uppsats, KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Författare :Clara Nermark; [2023]
    Nyckelord :Onboard orbit determination system; GNSS; nanosatellite; testing; verification and validation; Ombord banbestämning; GNSS; nanosatellit; testning; verifikation och validering;

    Sammanfattning : When developing products for space, including nanosatellites, the verification and validation process is a mandatory part of any project conducted within the European space industry. Within such a process, testing is a method for verification and validation. LÄS MER

  3. 2. Robotics Approach in Mobile Laser Scanning : Generation of Georeferenced Point-based Forest Models

    Master-uppsats, KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Författare :Tamas Faitli; [2023]
    Nyckelord :mobile laser scanning; rotating lidar; slam; real-time positioning; georeferencing; state estimation; lidar odometry; point-based forest model; forest harvester; forestry; mobil laserskanning; roterande lidar; slam; realtidspositionering; georeferens; tillståndsuppskattning; lidarodometri; punktbaserad skogsmodell; skogsskördare; skogsbruk;

    Sammanfattning : A mobile laser scanning (MLS) system equipped with a lidar, inertial navigation system and satellite positioning can be used to reconstruct georeferenced point-based models of the surveyed environments. Ideal reconstruction requires accurate trajectories that are challenging to obtain in forests. LÄS MER

  4. 3. Terrain Referenced Navigation with Path Optimization : Optimizing Navigation Accuracy by Path Planning

    Master-uppsats, KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Författare :Martin Gelin; [2022]
    Nyckelord :Terrain Referenced Navigation; Localization; Particle Filter; Rao-Blackwellized Particle Filter; Kalman Filter; Path Planning; Terrängbaserad navigering; Lokalisering; Partikelfilter; Rao-Blackwelliserat partikelfilter; Kalmanfilter; Banplanering;

    Sammanfattning : Terrain referenced navigation is a method of navigation that uses measurements of altitude above ground to infer the position of the vehicle, mainly aerial or underwater. This method provides an alternative to the commonly used satellite-based navigation. LÄS MER

  5. 4. Evaluation of drift correction strategies for an inertial based dairy cow positioning system. : A study on tracking the position of dairy cows using a foot mounted IMU with drift correction from ZUPT or sparse RFID locations.

    Master-uppsats, KTH/Skolan för industriell teknik och management (ITM)

    Författare :Maria Markovska; Ruben Svensson; [2019]
    Nyckelord :Inertial navigation system; IMU; PDR; dairy cows; drift correction; ZUPT; sparse locations.; Tröghetsnavigeringssystem; IMU; PDR; mjölkkor; driftkorrigering; ZUPT; sparse locations.;

    Sammanfattning : This thesis investigates the feasibility and performance of an inertial based positioning system for dairy cows in a barn environment. The investigated positioning method is pedestrian dead reckoning using inertial navigation with MEMS sensors. LÄS MER

  7. 5. Estimation of heading using magnetometer and GPS.

    Uppsats för yrkesexamina på avancerad nivå, Signaler och System

    Författare :Manne Henriksson; [2013]
    Nyckelord :Inertial navigation; magnetometer; heading; quaternion; bäring; magnetometer; tröghetsnavigering; quaternion;

    Sammanfattning : One important part of inertial navigation is the estimation of the direction relative to the Earth’s geographic North Pole, the so called heading. In this project, a gyroscope and an accelerometer were used together in an Extended Kalman Filter with a quaternion as the state space variable, representing the attitude. LÄS MER
