Note to the Federal Ministry of Foreign Affairs of the Republic of Austria

The Secretariat of the International Atomic Energy Agency presents its compliments to the Federal Ministry of Foreign Affairs of the Republic of Austria and has the honour to refer to Section 4(b) of the Agreement between the Republic of Austria and the International Atomic Energy Agency regarding the Headquarters of the International Atomic Energy Agency, dated 11 December 1957. Section 4(b) of the Headquarters Agreement provides that

"The IAEA may establish and operate such additional radio and other telecommunication facilities as may be specified by supplemental agreement between the IAEA and the appropriate Austrian authorities."
The Secretariat desires to demonstrate at the Austria Centre Vienna, in conjunction with its General Conference, a very small aperture terminal (VSAT) satellite system. The terminal will be operated during the week prior to the General Conference beginning 11 September 1995 for testing purposes and during the General Conference from 18 to 23 September for the demonstration.

The Secretariat also desires to conduct a longer-term demonstration of an international verification concept, based on a VSAT network. The VSAT system which is the same system used for the aforementioned Conference demonstration, will be relocated to a position at the Headquarters Area and will be operated from October 1995 until January 1996.

The Agency will ensure that:

  1. The equipment is used only for the purpose indicated in this Note, taking all appropriate steps to prevent misuse of the equipment, in particular by third parties;

  2. The appropriate Austrian authorities are notified of any change in the design of or manner of operating the equipment;

  3. The personnel responsible for operating the equipment receive no communications other than those intended for it;

  4. The equipment is not used to link up with other telecommunication facilities; and

  5. The equipment does not disturb other telecommunication facilities in their operation;

  6. The operation of the equipment will be stopped for compelling reasons at the request of the Austrian authorities.

The Agency would be grateful if the competent Austrian Authorities could agree to the establishment and operation of the equipment referred to above and has the honour to propose that this proposal, together with the Ministry's note of reply, shall constitute a supplemental agreement pursuant to Section 4(b) of the Headquarters Agreement. The Agency has the honour to propose further that this supplemental agreement shall have effect as of the date of the Ministry's note of reply.

The Secretariat of the International Atomic Energy Agency avails itself of this opportunity to renew to the Federal Ministry of Foreign Affairs of the Republic of Austria the assurances of its highest consideration.
