The ITU is an agency of the United Nations that is responsible for assigning and allocating "parking spots" or orbital slots on the GEO for. To verify the GEO satellite classes published in the. The. ITU-R coordination of orbital slots prevents radio interference preventing malfunctioning of satellite services. KEY. . Longitudinal positions can be derived from orbital element data using the PyEphem Python Library [8, 9]. The ITU is an essential organization in the global management of satellite orbits and radio frequencies. Today, any compa- ny or nation planning to launch a satellite to GEO must apply to the ITU for an orbital slot, and popular regions over North America, Europe. It then falls to administrations to assign frequencies and orbital positions, to apply the appropriate procedures from the Radio Regulations (international. 1. ITU at a glance. You can share a slot between satellites and even operators if you have spectrum. Satellite orbital slots are valuable and limited resources, which need to be planned and managed. GUIDELINES ON SATELLITE NETWORK FILING. ROLE. 48 Consequently, Tonga, with no satellite capability of its own, was able to lock up multiple orbital slots by following the present ITU procedures. By assigning orbital slots for GEO. Depending on the nature of the spectrum, you can put more or. Introduction. Page Meet.
