SERVICE CHARACTERISTICS
All services permitted within the Fixed Satellite Service are considered appropriate to the United Kingdom requirements and any allotment provided for the United Kingdom must be capable of supporting these services. The following list is given to indicate the range of requirements but should not be considered exhaustive:-
Analogue and digital telephony transmission
Telex and associated services
Digital Computer data transmission
Analogue and Digital Television transmission including
distribution
Data distribution and gathering using Very Small Aperture
Terminals (VSATs)
Remote printing.
All such services shall be protected from interference to a sufficient extent so as to ensure that the quality of service is in accord with the appropriate CCITT and CCIR recommendations.
ORBITAL LOCATIONS
The United Kingdom recognises the value that could be obtained if satellites used in the FSS Allotment Plan could also carry other payloads and to this end in so far as this might be
possible without adversely affecting the preparation of an Allotment Plan, flexibility of orbit location is useful
in aligning with other arrangements such as BSS locations and other FSS locations.
BANDS AND POLARISATIONS
For the requirement of the United Kingdom and its overseas dependent territories the United Kingdom wishes to employ the full 800 MHz of the Allotment Bands.
The Sub-Regional requirement need only be met in the 500 MHz at 11/13 GHz.
It is assumed that at all locations administrations will be free to utilise dual polarisation as a means of increasing traffic cpacity.
DEFINITION OF SERVICE AREAS
The service area requirements are defined by a series of latitude and longitude test points around which a best fit ellipse should be fitted (assumed to represent the satellite antenna characteristics). This ellipse should represent an area within which the service provided will not vary by more than 3 dB from the beam peak and within which the interference from other systems
