While the International Telecommunications Union (ITU) is often associated with “licensing,” its primary responsibility is the global coordination of radio-frequency spectrum and orbital resources rather than the direct issuance of operating licenses.
Direct licensing remains the sovereign jurisdiction of individual Member State administrations (e.g., the FCC in the U.S. or Ofcom in the UK).
The ITU’s mandate, governed by the ITU Constitution and the Radio Regulations (RR) treaty, is to ensure that satellite systems operate harmoniously without causing harmful interference across international borders.
First implemented as the World Radiocommunication Conference (Geneva, 1995) and recently updated in 2024 (The Radio Regulations, Edition of 2024), it ensures global coordination to prevent harmful interference between radio stations, facilitates equitable access to spectrum resources, and is legally binding for member states.
Core Responsibilities in Satellite Regulation
The ITU-R (Radiocommunication Sector) manages three primary pillars to ensure the orderly use of outer space:
1. Allocation of Frequency Bands
The ITU manages the Table of Frequency Allocations, which divides the radio spectrum into various “services” (e.g., Fixed-Satellite, Broadcasting-Satellite, Mobile-Satellite). This prevents a satellite from broadcasting on a frequency reserved for terrestrial emergency services or aviation.
2. Interference Mitigation and Coordination
Because radio waves do not stop at national borders, the ITU oversees a cooperative registration process.
- Master International Frequency Register (MIFR): The ITU maintains this global database. Recording an assignment in the MIFR provides “international recognition” and protection for that frequency use.
- Bilateral Negotiations: If a proposed satellite might interfere with an existing system, the ITU facilitates technical discussions between the concerned nations to find a solution (e.g., shifting orbital positions or adjusting power levels).
3. Equitable Access to “Limited Natural Resources”
Under Article 44 of the ITU Constitution, radio frequencies and orbital slots (particularly the Geostationary Orbit, or GEO) are recognized as limited natural resources. The ITU’s responsibility is to ensure they are used:
- Rationally and Efficiently: Preventing “spectrum warehousing” where a nation claims a slot but never launches a satellite.
- Economically and Equitably: Ensuring that developing countries have guaranteed access to orbital resources in the future, even if they do not currently have the technology to use them.
The Four-Step Registration Process
While the ITU does not “grant a license” to a company, it must approve the filing submitted by a nation on behalf of that company. The process generally follows these steps:
- Advance Publication Information (API): The national administration sends a general description of the satellite to the ITU.
- Coordination: If required, the nation negotiates with other countries to ensure no harmful interference will occur.
- Notification: The final technical characteristics are submitted to the ITU Radiocommunication Bureau for examination.
- Recording: If compliant, the assignment is recorded in the MIFR, granting the operator international protection.
Prevention of “Spectrum Warehousing”
To ensure resources are actually used, the ITU enforces a seven-year deadline. If a satellite is not “brought into use” (placed in its assigned orbit and transmitting) within seven years of the initial filing, the regulatory rights expire. For large constellations (NGSOs), the ITU also enforces milestone-based deployment rules (e.g., 50% of the fleet must be launched within five years of the start of operations).
