What the procedure looks like when a country publishes all of it. Every heading says who acts and what comes out of it. Open the ones you need; every requirement carries the article it comes from, with a link to the instrument.
Under international law, a State that launches an object into outer space must record it. That record determines two things: which State exercises jurisdiction and control over the object while it is in orbit, and which State is liable for any damage it causes. The obligation was agreed in 1975 and binds 77 States today. Building the national machinery that makes it work, which means a register, a procedure and a designated authority, is what remains outstanding in most countries.
A university in a developing country builds a satellite the size of a shoebox. It costs less than a delivery van. It will photograph farmland so the agriculture ministry can see which crops are failing. The university has no rocket, so the satellite hitches a ride on someone else's, is carried up to the International Space Station, and is pushed out of a hatch into orbit.
From that moment it belongs to somebody, and somebody is answerable for it. Every card below says who, and ends with what it means for this satellite.
These terms are not interchangeable, and most confusion in national practice comes from treating them as if they were. Hover any underlined term anywhere in this prototype to see its definition.
| Term | What it means | Where it is defined |
|---|---|---|
| Space object | Not only the satellite. The term includes component parts of a space object as well as its launch vehicle and parts thereof. Rocket bodies and debris are space objects too, and are largely unregistered | Registration Convention, art. I(b) |
| Launching State | Four ways to become one, and a State can be one without ever touching a rocket: it launches, it procures the launching, the launch happens from its territory, or from its facility. A single launch can have several launching States at once | Registration Convention, art. I(a) |
| State of registry | The launching State on whose registry the object is carried. Only one per object. Where there are several launching States they must agree which of them registers it | Registration Convention, arts. I(c) and II.2 |
| Operator | The entity that actually runs the object: a company, a university, a public body. No treaty defines it; national law does. An operator supplies the data and holds the licence, but cannot register anything: a submission sent by an operator is not a valid registration | National law. The limit comes from UNOOSA practice |
| Permanent Mission | The State's diplomatic office accredited to the United Nations in Vienna. It is the only channel through which registration information reaches the Secretary-General | UNOOSA, Resources on Space Object Registration |
| Note verbale | An unsigned formal diplomatic communication written in the third person, exchanged between a mission and an organization. It is the instrument that carries both the article II.1 notification and each object's data | Diplomatic practice; the form of every published notification in the ST/SG/SER.E series |
| Who is bound | The launching State, not the university |
|---|---|
| What it must do | Authorise the activity in advance, and keep supervising it for as long as it lasts |
| When | Before launch, and continuously afterwards |
| How | By issuing a licence under a national rule, and by checking the operator keeps to it |
| On what basis | Outer Space Treaty 1967, article VI; element 3 of resolution 68/74 |
| If it does not | The State is in breach, and has no legal grip on an object it will answer for anyway |
Our satellite: the university asks its own government for permission. Not the country that owns the rocket. Its own.
| Who is bound | Every State Party to the Registration Convention. 77 as at 1 January 2026. Once it registers an object it becomes its State of registry |
|---|---|
| What it must do | Keep a national register of the space objects it launches |
| When | From the moment it becomes a launching State; in practice, before its first satellite goes up |
| How | Any way it likes. The treaty says the contents and conditions are "determined by the State of registry concerned" |
| On what basis | Registration Convention 1975, article II.1 |
| If it does not | Nothing happens immediately, and that is the problem. There is no penalty, so the duty quietly goes unmet for decades |
Our satellite: the country needs a list. A spreadsheet would satisfy the treaty. What almost no country has is the procedure that gets a satellite onto the list.
| Who is bound | The same State, acting through its Permanent Mission in Vienna |
|---|---|
| What it must do | Inform the Secretary-General that it has established a national register, and on what terms it is kept |
| When | Once. Never repeated |
| How | A note verbale of half a page. The model is in tab 5 |
| On what basis | Registration Convention 1975, article II.1, second sentence |
| If it does not | The State never appears on the United Nations list of national registries. Only 41 States appear on it. One is African. One is from the Gulf |
Our satellite: this is the cheapest obligation in the whole of space law and the most widely ignored. One letter, once, in the lifetime of a country.
| Who is bound | The State of registry. One State per object, agreed among all launching States |
|---|---|
| What it must do | Furnish nine items: which State, the name of the object, its designator, the date and place of launch, four orbital numbers, and what it is for |
| When | "As soon as practicable" after the object is in orbit. The treaty sets no number of days |
| How | Note verbale from the Permanent Mission, using form UNOOSA/REG/FRM/1 |
| On what basis | Registration Convention 1975, article IV.1 |
| If it does not | The object exists physically but not legally. Nobody can say for certain whose it is, and the State loses the jurisdiction article VIII would have given it |
Our satellite: university to space agency, agency to foreign ministry, ministry to mission in Vienna, mission to the United Nations. Four hands. Every hand is a place where it stops for six months.
| Who is bound | The State of registry |
|---|---|
| What it must do | Notify the Secretary-General of objects no longer in Earth orbit |
| When | To the greatest extent feasible and as soon as practicable |
| How | Same channel, same form |
| On what basis | Registration Convention 1975, article IV.3 |
| If it does not | The global register fills with objects that no longer exist, which makes it less useful for everyone, including for avoiding collisions |
Our satellite: a shoebox at 400 kilometres burns up in a year or two. Someone has to remember to say so.
| Who is bound | The launching State, which can be more than one State at once |
|---|---|
| What it must do | Compensate. On the ground or against aircraft, liability is absolute: it pays even if nobody was careless. Elsewhere, it pays if at fault |
| How | Through a claim between States. No financial ceiling in the treaty |
| On what basis | Liability Convention 1972, articles II and III |
| If there is no insurance | The public purse pays. This is why national rules require the operator to insure: not to protect the operator, but to protect the State from a liability it already carries |
Our satellite: if the shoebox hits somebody else's satellite, the bill goes to the country, not to the university. That is the sentence that makes finance ministries pay attention.
| Who | Can | Cannot |
|---|---|---|
| The operator university, company, public body |
Build and fly the space object. Apply for the licence. Supply the technical data | Register anything. A submission sent straight to the United Nations by an operator is not a valid registration |
| The State agency, ministry, permanent mission |
Authorise, supervise, keep the national register, notify the United Nations through its mission | Escape liability by pointing at the operator. The State answers, then recovers from the operator if national law allows |
| The United Nations UNOOSA, Vienna |
Keep the global register, publish it free of charge, help States write their own rules | Register an object for a State, or oblige a State to act. It records what States send |
The confusion that costs countries years. The ITU decides on what frequency and from what orbital slot you may transmit. Its register is a register of frequencies. UNOOSA keeps a register of objects, so it is known which State is in charge of each thing up there. Different procedures, different organizations, different channels: the ITU is approached through the national telecommunications administration, the United Nations through the Permanent Mission. A satellite can have its frequency and be unregistered, and the other way round.
So what is missing is not the law: 77 States already signed up. Not the destination: the United Nations register is public, free and searchable, in tab 6. What is missing in most countries is the middle, a procedure at home that turns the obligation into something an operator can actually do. That is what the rest of this shows.
The procedure as a country would publish it. Thirteen steps, each with the actor who performs it and the thing that comes out of it.
| Requirement | Evidenced by | Why it is asked, and under what authority |
|---|---|---|
| Valid space activity licence | Number and date of the administrative act | The parent procedure. Without State authorisation there should be no entry. From Outer Space Treaty article VI, and element 3 of resolution 68/74 |
| Liability cover | Policy or guarantee: insurer, number, amount, period | The State is internationally liable without ceiling under the Liability Convention 1972. Insurance protects the State, not the operator |
| Frequency coordination | Evidence of filing with the ITU by the national telecommunication administration | Advance Publication and coordination under ITU Radio Regulations article 9, recording in the Master International Frequency Register under article 11. Without a frequency the satellite cannot operate even if registered |
| Measured orbital parameters | Nodal period, inclination, apogee, perigee | Registration Convention article IV.1(d). These four cannot be omitted |
| Debris mitigation plan | Technical document | COPUOS Space Debris Mitigation Guidelines |
| # | Step | Who performs it | What comes out |
|---|---|---|---|
| 0 | Tell the United Nations the register exists | Permanent Mission in Vienna | A note verbale, published by the United Nations as an ST/SG/SER.E/INF document. Once in a country's lifetime |
| 1 | Apply for a space activity licence | Operator | A filed application with a file number |
| 2 | Technical and legal assessment | National authority | An assessment report. Belgium requires an external opinion for CubeSats, at the applicant's cost |
| 3 | Decision on the licence | Competent authority, usually a minister | An administrative act with number and date, which later travels inside the register entry |
| 4 | Pre-registration | National authority | A national registration number, assigned before launch so the object is identifiable from the first minute. Belgian practice |
| 5 | Agree who registers the object | National authority with the other launching States | A written understanding. One object, one register, under article II.2 |
| 6 | Launch and notice of success | Operator | A launch notice within the period set by national rule |
| 7 | Submit the final data | Operator | The completed national form with the real orbital parameters |
| 8 | Verification | National authority | Confirmation that the data are consistent and match the licence |
| 9 | Entry in the register | National authority | A public register entry and a certificate of entry for the operator. See tab 3 |
| 10 | Transfer to the foreign ministry | National authority | An internal note carrying the completed United Nations form |
| 11 | Notification to the United Nations | Permanent Mission in Vienna only | A note verbale with the form, by diplomatic channel and by e-mail to soregister@unoosa.org |
| 12 | Publication | UNOOSA | An ST/SG/SER.E document and the object's appearance in the global online index |
| 13 | Maintenance | National authority, on the operator's reports | Updated entries for change of operator, disposal orbit and re-entry, the last one required by article IV.3 |
The mistake that keeps happening. A national space agency sends the form straight to UNOOSA and believes the object is registered. It is not. UNOOSA states it plainly: registration "can only be done by the Government of a State of registry through the Permanent Missions accredited to the United Nations… Direct submissions from national space agencies, academic institutions and private entities are not considered valid registration submissions." UNOOSA, Resources on Space Object Registration.
Thirty-nine fields in seven blocks. Each carries where the requirement comes from, which is what lets a country defend why it asks for each item and, more importantly, why it asks for nothing else. The tags are links.
Treaty required by the Registration Convention 62/101 recommended by the General Assembly National practice of real registers, not required by treaty
This is the thesis. The operator types once. Three different documents come out, each issued by a different actor, in a different format, for a different audience. Today, in the countries that do register, these three are prepared by hand, separately and months apart, which is where data is lost and where the procedure becomes expensive.

UNOOSA does four things before publishing: validation, was it sent through the official channel; verification, is the mechanism right, is there no conflict with article II.2, are the technical data consistent; document processing, editing and translation; and dissemination, publication in the online index.

Legal basis: Convention on Registration of Objects Launched into
Outer Space, 1975, articles II and IV; General Assembly resolution
62/101. Illustrative data, demonstration prototype.
Article II.1 of the Registration Convention requires each State Party to inform the Secretary-General that it has established its national register. Once. Half a page. It is the cheapest obligation in space law and the most widely ignored.
Of 193 Member States, only 41 have made this notification. Exactly one is African and one is from the Gulf. There are States that are Party to the Convention, have objects entered in the United Nations register, and have never notified that they hold a national register: they have been in breach for between three and forty-one years of a duty discharged with one letter. UNOOSA index of national registries.
The Permanent Mission of [STATE] to the United Nations (Vienna) presents its compliments to the Office for Outer Space Affairs and, in accordance with article II, paragraph 1, of the Convention on Registration of Objects Launched into Outer Space of 1975, has the honour to inform that [STATE] has established a national registry of space objects launched and carried on its registry.
The registry is maintained by [NATIONAL COMPETENT AUTHORITY], pursuant to [NATIONAL INSTRUMENT, number and date]. The conditions and terms under which it is maintained are as follows:
[NAME, TITLE, E-MAIL, TELEPHONE] is designated as the national focal point for matters relating to registration.
The Permanent Mission of [STATE] to the United Nations (Vienna) avails itself of this opportunity to renew to the Office for Outer Space Affairs the assurances of its highest consideration.
That is the argument for a pilot: a State can start with what it already has, and the full law comes later. Doing it in the other order is why the obligation has gone unmet for forty years in some countries.
Yes, the global register is public today, and free. Article III of the Registration Convention requires the Secretary-General to maintain it and provides for full and open access. Each entry appears as a document in the ST/SG/SER.E/… series, or A/AC.105/INF/… for submissions under resolution 1721 B (XVI), the voluntary channel used by States that are not Party.
| Where | What you can do there |
|---|---|
| Online Index of Objects Launched into Outer Space | The searchable global register. Filter by State, orbital status, launch facility, year and, critically, by whether registration information was submitted or not. That filter makes the gap visible object by object |
| Submissions by State and organization | One page per country: its status under the Convention, a link to its national register if it has one, whether it has a focal point, and every submission it has made. A country can see its own record in thirty seconds |
| Index of national registries | The article II.1 notifications. Forty-one States appear. This is the list a country joins by sending the letter in tab 5 |
| National focal points | Who to contact in each country. UNOOSA has details from more than seventy States and organizations |
ST/SPACE/95, Toolkit on Good Registration Practices for Objects Launched into Outer Space (2025), with a foreword by the Director of UNOOSA. It sets out good practice, the treatment of deployment from a space station, and how submissions are processed and published.
This prototype does not restate that toolkit. It turns it into a working procedure, which is the part UNOOSA does not do and UNCTAD does.
The global register is the destination, not the road. What does not exist in most countries is the national side: the register the State is required to keep, the procedure by which an operator gets into it, and the published page that tells that operator what to do. About 91.5 per cent of functional objects have been registered with the United Nations, but only 41 States have told the United Nations that they keep a national register at all. The gap is not in Vienna. It is in the capital.
Nothing here is invented. Every field, deadline and step comes from an instrument in force or from the practice of a real national register.
| Instrument | What it contributes |
|---|---|
| Convention on Registration, 1975 77 States Parties | Article II: the duty to keep a register and to notify it. Article III: the United Nations register and full and open access. Article IV.1: the data that cannot be omitted. Article IV.3: the duty to report re-entry. Article V: physical marking. Party count as at 1 January 2026, A/AC.105/C.2/2026/CRP.9/Rev.1 |
| Outer Space Treaty, 1967 118 States Parties | Article VI: the State authorises and continuously supervises its non-governmental entities, which is where the licence comes from. Article VIII: jurisdiction and control follow registration, which is why all of this exists |
| Liability Convention, 1972 100 States Parties | The State's liability for damage caused by its space object, which is what justifies requiring insurance |
The number that carries the argument: 118 States accepted that jurisdiction follows registration, but only 77 accepted the instrument that makes registration work, and only 41 have told the United Nations they keep a register at all.
| Instrument | What it contributes |
|---|---|
| Resolution 62/101 (2007) | The additional fields, the treatment of shared launches, and change of supervision |
| Resolution 68/74 (2013) | The elements of national space legislation, including authorisation and insurance |
| Form UNOOSA/REG/FRM/1 | The four-part structure of the notification and the exact format of each item. Also in Excel and Spanish |
| Toolkit ST/SPACE/95 (2025) | Good practice, deployment from a space station, and the publication process |
| Country | What was taken from it |
|---|---|
| Belgium | Pre-registration before launch, mandatory external opinion for CubeSats, the frequency and manoeuvrability fields, and full administrative traceability |
| Italy, Law 89/2025 | Manufacturer, constellation membership, and the supplementary register for transferred objects |
| United Arab Emirates | The end-to-end sequence of the procedure, as documented in ST/SPACE/95 |
| United Kingdom, South Africa, Chile | Models for publishing the register and for designating the competent authority |
What this prototype is not. It is not a government service and does not claim to be. It represents no State. Sample entries are illustrative. It is a demonstration of what the procedure looks like when published in full, made to be discussed with UNOOSA and with interested countries. Nothing typed here is transmitted or stored.
