Descripció del contingut i pla d'activitats:
The population of geostationary satellites is crucial for our modern life. The signals that they transmit are essential for multiple purposes (weather forecasting, telecommunications, entertainment, ...). However, their positions are sometimes known with rather large uncertainties, which may raise false collision alerts and increase operational costs. GMV is developing its own network of passive ranging stations to accurately determine the position of the geostationary satellites. Passive ranging is an innovative technology allowing the fast location of radio-emitting satellites with exquisite accuracy. The current TFM will focus on the use of passive ranging to greatly improve the position uncertainties of the geostationary satellite population. The work will also allow the characterization of the signal of the emitting satellites and their executed maneuvers. During this TFM, the student will deepen the understanding of software development, passive ranging capabilities and orbit determination tools in a sector that is expected to grow exponentially during the following years.
 
Overview (resum en anglès):
In this project, a feasibility study has been carried out to implement a specialised passive ranging system for satellites in the LEO orbital regime, based on a system previously developed for GEO, called Focusear. For this purpose, a simulator, Parasim, has been used and modified, which, based on a population of satellites and ground stations, simulates the whole process of passive ranging, from the creation of observation plans to obtaining the measurements and the orbital determination based on these measurements. Finally, each of the scenarios studied has been evaluated to determine which are feasible and which are the most promising.
