  1. 1. High Accuracy Positioning

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

    Author : Yichen Yang; [2020]
    Keywords : ;

    Abstract : The thrive of big data, cloud computing, and 5G communication lays a solid foundation for smart transportation and autonomous driving. But in these areas, accurate positioning is also indispensable. Current high accuracy positioning services are mainly based on Network RTK. READ MORE

  3. 2. Comparison of various drone positioning systems when creating surface models

    University essay from KTH/Rymdteknik

    Author : Nils Lundström; [2020]
    Keywords : ;

    Abstract : There are many applications where 3D models of landscapes can be used, suchas determining volume of objects, inspecting buildings and planning of infrastructure.One common way of creating 3D models of a geographical area is totake overlapping geotagged photos with a drone and then perform an aerotriangulation(AT).

  4. 3. State Estimation for Truck and Trailer Systems using Deep Learning

    University essay from Linköpings universitet/Reglerteknik

    Author : Daniel Arnström; [2018]
    Keywords : state estimation; observer; deep learning; neural network; convolutional neural network; EKF; truck; trailer; semi-trailer;

    Abstract : High precision control of a truck and trailer system requires accurate and robust state estimation of the system. This thesis work explores the possibility of estimating the states with high accuracy from sensors solely mounted on the truck. The sensors used are a LIDAR sensor, a rear-view camera and a RTK-GNSS receiver. READ MORE

  5. 4. Evaluation of digital terrain models created in post processing software for UAS-data : Focused on point clouds created through block adjustment and dense image matching

    University essay from Högskolan i Gävle/Samhällsbyggnad, GIS

    Author : Sabina Assefha; Matilda Sandell; [2018]
    Keywords : UAS; DTM; Pix4D; UAS Master; Block adjustment; Photogrammetry; UAS; DTM; Pix4D; UAS Master; Blockutjämning; Fotogrammetri;

    Abstract : Lately Unmanned Aerial Systems (UAS) are used more frequently in surveying. With broader use comes higher demands on the uncertainty in such measurements. The post processing software is an important factor that affects the uncertainty in the finished product. READ MORE

  6. 5. Development of a platform for evaluating a GNSS positioning system

    University essay from Uppsala universitet/Signaler och System

    Author : Simon Gollbo; [2018]
    Keywords : GNSS; Differential GNSS; uBlox;

    Abstract : The project aims to develop a platform for the demonstration and evaluation of Global Navigation Satellite Systems (GNSSs). The GNSS receivers used in the project are two uBlox NEO-M8P modules, one of which is used as a reference receiver in a differential GNSS setup. READ MORE
