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