Resolution 743 [COM5/7] |
| Description of work: |
This resolution relates to the band 42.5 - 43.5 GHz, where power flux density (PFD) limits were introduced to protect the radio astronomy service from emissions from GSO FSS and BSS systems. In article 5.BC05 these are defined as absolute (100% of time) levels, but in this resolution it states that in Region 2 they can be exceeded for not more than 2% of time. However it also calls for studies and development of Recommendations to establish the appropriate balance between this percentage of time and the associated impact on radio astronomy observations. |

WP 4A, WP 7D |
| How Visualyse products can help: |
Visualyse Professional can be used to analyse sharing between satellite services such as the FSS and BSS and the radioastronomy service in this band, calculating interference using measures such as PFD and EPFD. |
| How Transfinite consultants can help: |
We can undertake studies including analysis of sharing between the services covered by this resolution, 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 sharing with the radio astronomy in this band from a series of sharing studies performed. |
