  • Satellite Visualization in Web Browsers
    Saugat Awale, Jaya Kumar Bidari Satellite Visualization in Web browsers Metropolia University of Applied Sciences Bachelor of Engineering Information Technology Bachelor’s Thesis 18 March 2020 Abstract Author Saugat Awale, Jaya Kumar Bidari Title Satellite Visualization in Web browsers Number of Pages 45 pages Date 18.03.2020 Degree Bachelor of Engineering Degree Programme Information Technology Professional Major Software Engineering Instructors Janne Salonen ‘Satellite visualization’ refers to representing the real-time position of the satellite in its orbit with respect to earth’s surface as accurately as possible. Traditionally, the satellite’s graphical representation is executed in single-user desktop applications which make it difficult for multiple users in different workstations to view the same aerospace simulation of a satellite. This study researches the solution to the aforementioned problem. In this work, a brief theoretical background regarding the physics of satellite propagation is discussed. After the discussion, each column of a TLE is defined. When the geometry of orbit of a satellite is well understood, a web-based application is proposed to visualize the same trajectory of a satellite in multiple workstations. The planning section describes the architecture of the proposed web application. It also lists the tools and technologies used for the project and explains the benefits of each tool. In the analysis part, error of time and coordinates is calculated. The error lies within the margin as defined by the satellite operators. As a result, the satellite was successfully represented in a web browser and the same Satellite telemetry could be viewed from multiple workstations. It is concluded that the challenge to view the same visualization in multiple workstations using a web browser is solved.
