Article 1 
This Decision sets out the responsibilities to be exercised by the Council and the HR to avert a threat to the security of the Union or one or more Member States or to mitigate serious harm to the essential interests of the Union or of one or more Member States arising from the deployment, operation or use of the European Global Navigation Satellite System, in particular as a result of an international situation requiring action by the Union or in the event of a threat to the operation of the system itself or its services.
Article 2 
In the event of such a threat, the Member States, the Commission or the GSA, as appropriate, shall immediately inform the Council and the HR of all the elements at their disposal which they consider relevant.

1. The Council, acting unanimously upon a proposal from the HR, shall decide on the necessary instructions to the GSA. 2. The GSA and the Commission shall provide advice to the Council on the likely wider impact on the GNSS of any instructions which it intends to issue. 3. The Political and Security Committee (‘PSC’) shall provide an opinion to the Council on any instructions proposed, as appropriate.
Article 4 
1. If the urgency of the situation requires immediate action to be taken before the Council has taken a decision under Article 3(1), the HR is authorised to issue the necessary provisional instructions to the GSA. The HR may direct the Executive Secretary-General or one of the Deputy Secretaries-General of the European External Action Service to issue such instructions to the GSA. The HR shall immediately inform the Council and the Commission of any instructions issued pursuant to this paragraph. 2. The Council shall confirm, modify or revoke the provisional instructions of the HR as soon as possible. 3. The HR shall keep his/her provisional instructions under constant review, amend them as appropriate or revoke them if immediate action is no longer required. In any event, the provisional instructions shall expire four weeks after being issued, or upon a decision by the Council pursuant to paragraph 2.

Within six months from the adoption of this Decision, the HR shall prepare, with the support of experts from the Member States, and submit for approval to the PSC, the necessary early operational procedures for the practical implementation of the provisions set out in this Decision.

In accordance with prior international agreements concluded by the Union or the Union and its Member States, including those granting access to PRS pursuant to Article 3(5) of Decision 1104/2011/EU, the HR shall have the authority to conclude administrative arrangements with third States concerning cooperation in the context of this Decision. Such arrangements shall be subject to approval by the Council acting unanimously. 2. If such arrangements require access to Union classified information, the release or exchange of classified information shall be approved in accordance with the applicable security rules.
