In order to provide low-latency high-throughput Internet access all over the world, companies like SpaceX, Amazon, and OneWeb currently deploy and maintain Low Earth Orbit (LEO) satellite constellations. Thousands of small satellites orbit Earth at an altitude of roughly 500km. Such a system is perfect for supporting vehicular networks by means of providing Internet access even in regions in which cellular communication technologies like LTE or 5G are not available. For evaluating LEO satellite supported vehicular networks, the simulator Space_Veins is currently developed by us. It is based on Veins which simulates Earth’s surface as a plane without curvature. Space_Veins integrates LEO satellites in a Veins simulation given a tuple {azimuth angle, altitude angle, distance} relative to a well-defined Satellite Observer Position (SOP) in the simulation. In contrast to space_Veins, simulators dedicated for simulating LEO satellite constellation usually represent Earth as perfect sphere.
Goals of the thesis
This thesis aims at evaluating the difference between using the approach as implemented by space_Veins and representing Earth as a sphere. Depending on the method used for representing Earth, the relative positions of vehicles and satellites will differ. The software components, Space_Veins is based on, provide the processing capabilities for both representations. Basically, the following two steps need to be performed:
- Transforming satellites' and vehicles' positions into a WGS84 reference system
- Compare the relative measures azimuth angle, altitude angle, and distance between vehicles and satellites of both representations
