Agenda 1.17 |
| Resolution(s): |
Resolution 745 [COM5/14] |
| Description of work: |
This agenda item relates to the 1 390 - 1 392 MHz (E-s) and 1 430 - 1 432 MHz (s-E) additional allocations made during WRC 2003 to the fixed satellite service operating feeder links for non-GSO MSS systems where the service links are under 1 GHz. However the CPM Report indicated that studies of compatibility with other services allocated in this band were not complete, indeed there were suggestion that sharing with EESS (passive) in particular, could be problematic. Services in these bands includes the fixed, mobile, radiolocation, EESS (passive), radio astronomy, space research (passive) and aeronautical mobile. These allocations are therefore not be used until studies are completed on:
i) sharing studies on operational and technical means to facilitate sharing in the uplink direction in the band identified and others around 1.4 GHz;
ii) sharing studies on operational and technical means to facilitate sharing in the downlink direction in the band identified and others around 1.4 GHz;
iii) validate that the unwanted emissions from the FSS feeder links would meet the protection requirements of the passive services
iv) to study the PFD levels required to protect the EESS (passive)

| How Visualyse products can help: |
Visualyse Professional can be used to study compatibility between non-GSO FSS feeder links for non-GSO MSS systems in both the Earth to space and space to Earth direction, and with the other services potential effected by this agenda item including fixed, mobile, broadcast, broadcast satellite, radio astronomy, EESS (passive), space research (passive) and radiolocation. |
| How Transfinite consultants can help: |
We can undertake studies including analysis of sharing between the services covered by this agenda item, and identify suitable system characteristics and sharing criterias, and provide contributions and representation at relevant ITU-R Working Parties. We have extensive experience in issues relating to examining compatibility between feeder links for non-GSO mobile satellite services and other services from extensive studies and representation at ITU-R in support a non-GSO MSS operator. |
