Re: [amsat-international] (no subject)

Hi Ray,

It will be interesting to see if anything changes. My interpretation of the
ITU RRs is that the removal of the words "inform the IFRB" (actual wording
'inform the Bureau') may be of no consequence as this matter is perhaps
addressed in S6.7 and elsewhere.

Similarly the requirement to "terminate immediately" differs little from
that of S22.1. The requirement for our service is for sufficient ground
stations to be established before launch! It does not require world-wide
coverage however it would require that sufficient provision was made for (I
guess) such contingencies as folk on holiday, amateur radio gear problems,
the satellite's orbit. Thus the requirement is really no different for
University-type (or any other type) satellites which would have to operate
outside the amateur service (and frequencies) to be disqualified from the
25.11 "before launch" requirement.

73, Terry.

>From Michael Owen's article:

"The Amateur-satellite service


"25.11 Administrations authorizing space stations in the amateur-satellite
service shall ensure that sufficient earth command stations are established
before launch to ensure that any harmful interference caused by emissions
from a station in the amateur-satellite service can be terminated
immediately (see No. 22.1).

"The new provision avoids the repetition in different words of regulations
that already apply to the stations, and simply requires that sufficient
earth command stations are established before launch."

If I read it correctly, the requirement in Article 25.11 that
administrations inform the IFRB (now the Radiocommunication Bureau) of
prospective amateur space station launches has been done away with.  This
should result in the elimination of the U.S. notification requirement in 47
CFR Sec. 97.207(g), and similar requirements in other countries.

On the other hand, the requirement that harmful interference be terminated
has been strengthened to require that it be terminated "immediately."  Thus,
programs with only one command station inherently cannot qualify, as
sufficient command capability must exist throughout the world to turn off
satellites "immediately."  Fortunately for the likes of AO-7, this applies
only to satellites launched after the effective date of these regulations,
but would appear to rule out university-type satellites with only one
command station.
