Convention on Registration of Objects Launched into Outer Space

Member States conducting space launches have been requested by the Committee to provide the United Nations with information on their launchings. A registry of launchings has been maintained by the Secretariat since 1962, in accordance with General Assembly resolution 1721 B (XVI), and information from Member States has been issued in United Nations documents in the A/AC.105/INF series. Since the Convention on Registration of Objects Launched into Outer Space entered into force in 1976, another register of launchings has been established for information received from Member States and intergovernmental organizations that are parties to the Convention.

As of 1 January 2008,  51 States have ratified, 4 have signed and two international intergovernmental organizations (European Space Agency and European Organization for the Exploitation of Meteorological Satellites) have declared their acceptance of the rights and obligations provided for in the Registration Convention. The information received in accordance with the Convention has been issued in United Nations documents in the ST/SG/SER.E series. The A/AC.105/INF series continues with information provided by States who are not party to the treaty.

The Registration Convention provides that the launching State should furnish to the United Nations, as soon as practicable, the following information concerning each space object:

  • Name of launching State;
  • An appropriate designator of the space object or its registration number;
  • Date and territory or location of launch;
  • Basic orbital parameters, including:
    • Nodal period (the time between two successive northbound crossings of the equator - usually in minutes);
    • Inclination (inclination of the orbit - polar orbit is 90 degrees and equatorial orbit is 0 degrees);
    • Apogee (highest altitude above the Earths surface - in kilometres);
    • Perigee; (lowest altitude above the Earths surface - in kilometres);
  • General funtion of the space object.

Under these arrangements information has been received from Algeria, Argentina, Australia, Brazil, Canada, China, Chile, Czech Republic, France, Germany, Greece, India, Israel, Italy, Japan, Kazakhstan, Luxembourg, Malaysia, Mexico, Nigeria, Pakistan, Republic of Korea, Russian Federation, Spain, Sweden, Turkey, Ukraine, United Arab EmiratesUnited Kingdom of Great Britain and Northern Ireland and the United States of America as well as from the European Space Agency (ESA) and the European Organisation for the Exploitation of Meteorological Satellites (EUMETSAT).
