  1. 1. Flight dynamics multi-mission software development for optical link planning and execution

    University essay from KTH/Lättkonstruktioner, marina system, flyg- och rymdteknik, rörelsemekanik

    Author : Giacomo Dal Toso; [2023]
    Keywords : Generic Planning Tool; Visibility Service; Link Support Service; Visibility Windows; Flight Dynamics; Mission Planning;

    Abstract : The Generic Planning Tool (GPT) is a new software package being developed by the Flight Dynamics team at DLR. In an era where laser communications are becoming more and more relevant to data transmission for space missions, the GPT’s purpose is to compute highly accurate visibility windows and provide a wide variety of support information for both satellite-to-ground and inter-satellite links.

  3. 2. Design of a Dielectric Radome using a Ray-Tracing Model for Satellite Communications

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

    Author : Flores Espinosa Núria; [2023]
    Keywords : Dielectric radome; Ray tracing; Array antenna; Lens antenna; Satellite communications; Radom dielèctric; Traçat de Rajos; Arranjament d’antenes; Antena de lent; Comunicacions per satèl·lit; Dielektrisk radome; Strålspårning; Gruppantenn; Linsantenn; Satellitkommunikation;

    Abstract : In recent years, there has been a huge increase in the use of satellite communications. This has led to a need for more capacity, which can be solved by moving towards higher frequency bands in search of higher bandwidths. READ MORE

  4. 3. FPGA Implementation of an Online Free-Space Optical Communications Test-Bed

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

    Author : Hamza Mahmoud; [2023]
    Keywords : Test-bed; FPGA design; PRBS; FSO; Optical communication; Testbädd; FPGA-design; PRBS; FSO; Optisk kommunikation;

    Abstract : Free Space Optical (FSO) satellite communications is proving to be a key enabling technology for global connectivity with the ability to provide connection across Europe with only 12 ground stations. For this, Deutsches Zentrum für Luft- und Raumfahrt (DLR) is working on implementing a robust communication system for FSO on a Xilinx RFSoC Field Programmable Gate Array (FPGA)( ZU28DR). READ MORE

  5. 4. Going Public in Difficult Times - A Case Study on the Iridium Space SPAC

    University essay from Handelshögskolan i Stockholm/Institutionen för finansiell ekonomi

    Author : Fabian Binder; Devon Carbone; [2022]
    Keywords : Special purpose acquisition company SPAC ; Financial Crisis; Satellites;

    Abstract : This case study finds that a special purpose acquisition company (SPAC) was utilized by Iridium Communications (Iridium) as alternative equity financing when all other options had been eliminated. SPACs present certain problems with warrants and dilution, but they are flexible in structure. READ MORE

  6. 5. Far-field pattern synthesis of transmitarray antennas using convex optimization techniques

    University essay from KTH/Tillämpad fysik

    Author : Marie Defives; [2022]
    Keywords : Applied physics; Transmitarray antennas; convex optimization; Tillämpad fysik; Transmitarray-antenner; konvex optimering;

    Abstract : Transmitarrays antennas (TAs) can be seen as the planar counterpart of optical lenses. They are composed of thin radiating elements (unit cells) which introduce different local phase shifts on an incident electromagnetic wave, emitted by a primary source, and re-radiate it. READ MORE
