Frequently Asked Questions:
Q1: Why do we submit data of space and terrestrial stations to ITU?
Ans: It is important to submit data of both space and terrestrial stations to ITU, so that the associated frequency assignments get registered in the Master International Frequency Register (MIFR), thereby receiving international recognition in accordance with the Provisions of Article-8 of the ITU-R Radio Regulations.
Q2:What do we mean by a notifying administration at ITU?
Ans: As per RR No. 1.2 of Article-1 of the ITU-R Radio Regulations, “any governmental department or service responsible for discharging the obligations undertaken in the Constitution of the International Telecommunication Union, in the Convention of the International Telecommunication Union and in the Administrative Regulations (CS 1002)”.
Q3: What is satellite frequency coordination?
Ans: The satellite frequency coordination is a mechanism in which two or more parties (responsible for their respective satellites) engage in technical / regulatory negotiations for the smooth and interference operation of satellite networks. This process also involves exchange of technical data related to satellites and other radio systems operating on equal rights in the frequency bands under consideration.
Q4: What is the purpose of satellite frequency coordination?
Ans: The main purpose of satellite frequency coordination is to ensure that the new satellite entering into the market of existing so many other operational radio systems, operates without causing or receiving harmful interference. As per the CS 37 of the Constitution of the ITU, the “Member States are bound to abide by the provisions of this Constitution, the Convention and the Administrative Regulations in all telecommunication offices and stations established or operated by them which engage in international services or which are capable of causing harmful interference to radio services of other countries”.
Q5: Can you provide some information about the ITU?
Ans: The ITU (International Telecommunication Union) is the United Nations specialized agency for information and communication technologies. ITU was founded in Paris in 1865 as the International Telegraph Union. It took its present name in 1934, and in 1947 became a specialized agency of the United Nations. ITU is responsible to allocate global radio spectrum and satellite orbits, develop the technical standards that ensure networks and technologies seamlessly interconnect, and strive to improve access to ICTs to underserved communities worldwide.

Q6: Does ITU have an authority to enforce its rules?
Ans: All the Member States of ITU are sovereign in their decisions when it comes to rule making in their own boundaries, however, for the purpose of harmonization and interference free operation of wireless systems across the globe, the Member States have moral responsibility to abide by the rules and regulations of ITU (to the extent possible) as the Member States are signatory to the Convention and Constitution of ITU having a treaty status.
Q7: What are the benefits of being a member of ITU?
Ans: The ITU provides a unique, neutral and global platform to come together for the purpose of sharing ideas, knowledge and exchange best practice. It also provides an opportunity to its members to agree on new standards through consensus and a most transparent and fair environment. At ITU the members have an equal and ample chance to safeguard their interests in respective fields of ICTs.
Q8: What is the meaning of term AGREEMENT used in satellite frequency coordination?
Ans: The Agreement of Frequency Coordination or shortly referred as Agreement is the outcome of the process of frequency coordination between the two administrations listing all the operational conditions/ parameters to applied to the satellite networks of both sides.
Q9:Why do we need the Radio Regulations and related mechanisms?
Ans: The RRs and related mechanisms are essentially required for the efficient assignment/ coordination of radio frequencies and associated orbital positions in the geostationary orbit.
Q10:What are the three major steps for satellite filing procedures at ITU?
Ans: The three major steps in satellite filing procedures at ITU are the submission of API, Coordination Data and Notification Data as per Article-9 and Article-11 of the ITU-R Radio Regulations.
Q11:What is the regulatory time period for brining into use (BIU) a satellite network?
Ans: The current BIU time period for the satellite network as per RRs is seven years, starting from the date of submission of API. Previously, this limit of BIU for a satellite network was nine years from the date of submission of API.
f Q12: What does the term BIU (Brining into use) stand for in the satellite communications?
Ans: The BIU means placing a satellite at the specified orbital position in geostationary earth orbit and to start provision of service.
Q13:What do we mean by priority in frequency coordination of satellite networks?
Ans: The RRs and related mechanisms are essentially required for the efficient assignment/
Q14:What is the general life time of a GSO satellite?
Ans: The life time of most of the GSO satellite ranges from 15 to 20 years.
Q15:What is the most critical factor in limiting the life of a satellite?
Ans: The quantity of fuel on board is the limiting factor in determining the life of a satellite.
Q16: Do we need frequency coordination in planned bands as well?
Ans: Yes, frequency coordination would be required in planned bands if the administration responsible intends to modify their original planned assignments.
Q17: What do we mean by FILING?
Ans: Filing is the term used to submit data (technical and frequency coordination information) to ITU at different stages. In simple words we can say that filing refers to a paper satellite.
Q18: What is the distance of satellite from earth in the geostationary earth orbit?
Ans: The distance of satellite in geostationary earth orbit from earth is approximately 35,786 Km.
