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