On matters related to navigation policy and the radio frequency spectrum, ICAO coordinates its work with IMO and ITU, respectively.

E. International regulations for the use of radio spectrum

I compared the radio waves spectrum the size of it with the size of the visible light spectrum.

E. International regulations for the use of radio spectrum 104 106 16

The Radio Regulations, a binding international treaty setting out the procedures for all radio communication services, contained further detailed regulations and procedures governing orbit spectrum use.

And finally, about 100 years ago, the harnessing of electromagnetic spectrum to send sound and images through the air radio and television.

One concerns the regulation of the use of the geostationary satellite orbit and the radio frequency spectrum allocated to space communication services.

Request to the International Telecommunication Union and its member States Ensuring equitable access to the geostationary satellite orbit radio frequency spectrum resources

(a) Continuing their efforts to maintain compliance with coordination and planning procedures concerning access to the geostationary satellite orbit radio frequency spectrum resources

4. Regulation of the use of the geostationary satellite orbit and the radio frequency spectrum allocated to space communication services 201 204 39

They reaffirmed that the radio electronic frequencies spectrum must be secured in favour of public interest and in accordance with the principle of legality.

The international regulatory regime governing the use of spectrum orbit resources was contained in the Radio Regulations, which complemented the International Telecommunication Union Constitution Convention.

Those characteristics make the region advantageous for observations of the galactic disk (in the radio part of the spectrum) and for observations requiring simultaneous access to both celestial hemispheres.

It believed that the orbit and the radio frequency spectrum were limited natural resources that should be used rationally, efficiently, economically and equitably for the benefit of all States.

(b) Spectrum allocation

Well, of course, as soon as anybody did look, which was after about 20 years, when radio astronomy really took off. Because it turned out the universe is absolutely full of all kinds of wonderful things radiating in the radio spectrum, much brighter than the Sun.

The Cairo office would have responsibility for the full spectrum of UNDCP concerns in the region, covering the overall policy, programme and coordination matters of UNDCP.

Participants recommended that, because of the ever increasing use of the orbit spectrum resources and the resulting likelihood of satellite congestion in the geostationary orbit, more serious consideration should be given at the World Radio Conference 1997 to the question of equitable access to and efficient use of the orbit spectrum resources.

You can see the spectrum of the Earth, this Earthshine spectrum, and that is a very clear signal.

Yes, let's turn on the radio. Radio?

(b) Intensifying their efforts to prevent the proliferation of notifications that reserve capacity without actual use, which could hinder equitable access to and efficient use of the geostationary satellite orbit radio frequency spectrum resources for all States,

But if you look at the spectrum, birds and us, we see red, green and blue and see that spectrum.
