5.549A
In the band 35.5-36.0 GHz, the mean power flux-density at the Earth’s surface,
generated by any spaceborne sensor in the Earth exploration-satellite service (active) or space
research service (active), for any angle greater than 0.8° from the beam centre shall not exceed
2
73.3 dB(W/m ) in this band. (WRC-03)
5.550A
For sharing of the band 36-37 GHz between the Earth exploration-satellite (passive)
service and the fixed and mobile services, Resolution 752 (WRC-07) shall apply. (WRC-07)
5.551H
The equivalent power flux-density (epfd) produced in the band 42.5-43.5 GHz by all
space stations in any non-geostationary-satellite system in the fixed-satellite service (space-to-Earth),
or in the broadcasting-satellite service operating in the 42-42.5 GHz band, shall not exceed the
following values at the site of any radio astronomy station for more than 2% of the time:
2
2
−230 dB(W/m ) in 1 GHz and –246 dB(W/m ) in any 500 kHz of the 42.5-43.5 GHz band
at the site of any radio astronomy station registered as a single-dish telescope; and
2
−209 dB(W/m ) in any 500 kHz of the 42.5-43.5 GHz band at the site of any radio
astronomy station registered as a very long baseline interferometry station.
These epfd values shall be evaluated using the methodology given in Recommendation
ITU-R S.1586-1 and the reference antenna pattern and the maximum gain of an antenna in the radio
astronomy service given in Recommendation ITU-R RA.1631 and shall apply over the whole sky and
for elevation angles higher than the minimum operating angle θmin of the radiotelescope (for which a
default value of 5° should be adopted in the absence of notified information).
These values shall apply at any radio astronomy station that either:
–
was in operation prior to 5 July 2003 and has been notified to the Bureau before
4 January 2004; or
–
was notified before the date of receipt of the complete Appendix 4 information for
coordination or notification, as appropriate, for the space station to which the limits
apply.
Other radio astronomy stations notified after these dates may seek an agreement with
administrations that have authorized the space stations. In Region 2, Resolution 743 (WRC-03) shall
apply. The limits in this footnote may be exceeded at the site of a radio astronomy station of any
country whose administration so agreed. (WRC-07)
5.551I
The power flux-density in the band 42.5-43.5 GHz produced by any geostationary space
station in the fixed-satellite service (space-to-Earth), or the broadcasting-satellite service operating in
the 42-42.5 GHz band, shall not exceed the following values at the site of any radio astronomy
station:
2
2
–137 dB(W/m ) in 1 GHz and –153 dB(W/m ) in any 500 kHz of the 42.5-43.5 GHz band
at the site of any radio astronomy station registered as a single-dish telescope; and
2
–116 dB(W/m ) in any 500 kHz of the 42.5-43.5 GHz band at the site of any radio
astronomy station registered as a very long baseline interferometry station.
These values shall apply at the site of any radio astronomy station that either:
–
was in operation prior to 5 July 2003 and has been notified to the Bureau before
4 January 2004; or
–
was notified before the date of receipt of the complete Appendix 4 information for
coordination or notification, as appropriate, for the space station to which the limits
apply.
Other radio astronomy stations notified after these dates may seek an agreement with
administrations that have authorized the space stations. In Region 2, Resolution 743 (WRC-03) shall
