    Sammanfattning : Bosch Rexroth is a company that manufactures radial piston hydraulic engines and accessories, commonly used in industries such as mining and marine applications. These engines generate significant torques during operation, often requiring the use of torque arms to handle the torque. LÄS MER

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

    Master-uppsats, KTH/Lättkonstruktioner, marina system, flyg- och rymdteknik, rörelsemekanik

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

    Sammanfattning : 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.
