  1. 1. Positioning in Non-Terrestrial Networks

    University essay from Lunds universitet/Institutionen för elektro- och informationsteknik

    Author : Soha Emara; [2021]
    Keywords : positioning; 5G; satellite; NTN; Technology and Engineering;

    Abstract : In 5G communications, Non-terrestrial Network (NTN) is envisioned to complement Terrestrial Network (TN) to increase network availability, scalability and continuity. Positioning of User Equipment (UE) is critical for the operation of NTN. Currently, NTN uses Global Navigation Satellite System (GNSS) for positioning. READ MORE

    Abstract : Airplanes have different ways to connect to the ground, including satellite air-to-ground communication (SA2GC) and direct air-to-ground communication (DA2GC). Each connection/link offers a different varying amount of transmission capacity over flight time. READ MORE

  4. 3. Aircraft to Aircraft Connectivity Analysis

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

    Author : Vasileios Megas; [2018]
    Keywords : ;

    Abstract : It is very common to feel the need to be connected, especially in cases where we are idle, such as in airplanes. Aircraft connectivity has already been implemented by using direct air-to-ground communication and satellite communication. READ MORE

  5. 4. Aircraft antenna array for seamless direct air-to-ground communication system

    University essay from KTH/Skolan för elektro- och systemteknik (EES)

    Author : Anton Gusarov; [2016]
    Keywords : ;

    Abstract : Today, data communication provided for passengers on board of commercial airliners is significantly limited and mostly relies on satellite systems. One of the solutions for this problem is a direct air-to-ground communication systems (DA2GC) able to provide much larger data throughput in a seamless manner. READ MORE
