The FCC and ITU have progressively reduced the required spacing down to only 2 degrees for C-band and Ku-band. 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 currently includes the ARSAT-1, ARSAT-2 and ARSAT. 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. orbital slot? 2. 2.

It. We have proposed measures that ensure orbital slots in the Plans will not be affected by additional satellite systems. More specifically, ARSAT is responsible for the use of the geostationary orbital slots 72° W and 81° W and associated frequencies.
