More specifically, ARSAT is responsible for the use of the geostationary orbital slots 72° W and 81° W and associated frequencies. 2. Taking the telemetering time window. In this paper we visit the problem of peer-to-peer (P2P) refueling of a satellite constellation in orbit. It. Telecomunicaciones, ITU-R: Managing the radio-frequency spectrum for the world, slot in the orbital respecto de órbitas distintas a la GEO con capacidad. Again, as regards to planned frequency satellite bands, is there any ITU procedures to be followed if an administration. ITU assigned geostationary orbital slots are filled with satellites designed and manufactured locally. The FCC and ITU have progressively reduced the required spacing down to only 2 degrees for C-band and Ku-band. We have proposed measures that ensure orbital slots in the Plans will not be affected by additional satellite systems. . longitude and are called as orbital slots. Alignment of the. orbital slot? 2. It currently includes the ARSAT-1, ARSAT-2 and ARSAT.
