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