Administration-Level Licensing

While the International Telecommunication Union (ITU) manages the global allocation of spectrum, it does not issue licenses directly to operators. Instead, national regulators govern the actual deployment and operation of satellite networks.

Before a satellite can launch or transmit a single signal, the operator must secure authorization from their chosen home regulator.

Flag-State Filings & The Home Regulator​

To operate a satellite, an operator must work through a single national administration that submits filings to the ITU on their behalf. This administration is known as the Notifying Administration or the Home Regulator.

The Maritime Flag-State Analogy​

This process is similar to the Maritime Flag-State Analogy:

A ship owner registers a vessel in a specific flag state (like Panama or Liberia) to obtain a license and sail in international waters under that country's legal protection and oversight. Similarly, a satellite operator registers and licenses their space station with a home regulator (e.g., the FCC in the US, Ofcom in the UK, or ISED in Canada). This country acts as the sponsor, notifying the ITU of the frequency assignments and taking responsibility for compliance under international space treaties.

Example Regulatory Frameworks​

Different home regulators apply their own domestic rules when acting as the notifying administration:

  • Federal Communications Commission (FCC - United States): Governs satellite authorizations under Title 47 CFR Part 25. The FCC is currently transitioning toward a streamlined, performance-based Part 100 structure to modernize its rules.
  • Ofcom (United Kingdom): Issues Space Technology licenses under the Wireless Telegraphy Act 2006 and works in tandem with the UK Space Agency.
  • Innovation, Science and Economic Development Canada (ISED - Canada): Issues spectrum and space station licenses under the Radiocommunication Act.

The US Surety Bond Mechanism (US-Only): To prevent "spectrum warehousing"—a situation where an operator files for spectrum and blocks competitors without actually launching satellites—the FCC requires GSO and NGSO licensees to post a Surety Bond (often valued between 1millionand1 million and 5 million) shortly after their license is granted.

The operator forfeits this bond if they fail to meet deployment milestones. The bond value decreases progressively as satellites are successfully launched and operated. This bond is a US-specific mechanism and is not standard practice for most other national administrations.

Space Station Licensing​

A space station license grants an operator the authority to construct, launch, and operate a satellite payload in a specific orbit using designated frequencies.

Technical Exhibits & Filings​

Securing this license requires submitting highly detailed technical exhibits demonstrating that the satellite will operate safely without causing harmful interference:

  • Orbital Parameters: Exact details on the orbit, including altitude, inclination, number of orbital planes, and the number of satellites in a constellation.
  • Antenna Patterns: Contour diagrams showing where the satellite beams will point and how power levels drop off outside the target coverage zone.
  • Link Budgets: Calculations demonstrating the power levels, signal-to-noise ratios, and suitability of the link without causing excessive out-of-band emissions.

Engineering Sign-Offs​

Because of the technical complexity of these exhibits, some administrations (such as ISED Canada) require that all technical models and radio frequency exhibits be formally certified and signed off by a Professionally Licensed Engineer (P.Eng. or equivalent) to guarantee technical accuracy.

Third-Party Liability Insurance​

National regulators often condition space station licenses on the operator securing third-party liability insurance. This insurance protects the launching state from financial claims in the event of an orbital collision or space debris damage under the 1972 UN Liability Convention.

Earth Station Licensing​

An Earth station is any ground-based terminal that communicates with a satellite. Licensing requirements differ drastically based on the terminal's size, mobility, and purpose:

Gateway vs. User Terminals​

  1. Gateway Stations (Hubs): Large, high-power antennas that handle heavy data trunking, network backhaul, and Tracking, Telemetry, and Control (TT&C). Due to their high power and fixed coordinates, they require individual, site-specific licenses.
  2. User Terminals (VSATs / Mobile Terminals): Smaller, lower-power dishes used by end consumers (e.g., sat-phones, marine terminals, or residential dishes). These do not require individual site licensing and are instead authorized under a Blanket License framework (detailed in Chapter 4).

Site Coordination & The Coordination Contour​

Fixed gateway stations share spectrum with existing terrestrial networks (such as point-to-point microwave links). Before a gateway license is issued, the operator must calculate a Coordination Contour—a geographical boundary mapping where the gateway’s signal could potentially interfere with terrestrial networks.

The operator must coordinate with every terrestrial licensee within this contour to ensure co-existence.

Geographical Scrutiny & Strategic Sites​

Certain remote and strategic gateway locations are heavily scrutinized by regulators due to geopolitical, environmental, or scientific constraints:

  • Svalbard, Norway: A popular location for polar-orbiting satellite downlinks due to its high latitude. However, applications are heavily vetted under the Svalbard Treaty to guarantee strictly non-military compliance.
  • Inuvik, Canada: Highly scrutinized by ISED for S-band and X-band TT&C operations for Earth Exploration-Satellite Services (EESS) to prevent frequency congestion and manage electromagnetic compatibility in the Arctic.

Backhaul Bottlenecks​

To minimize terrestrial interference, gateways are often placed in remote, isolated areas. However, this creates a major Backhaul Bottleneck:

  • High Fiber Costs: Laying fiber-optic cable to remote Arctic or desert gateway sites is often prohibitively expensive.
  • Alternative Backhaul: Operators must often rely on terrestrial microwave links or dedicated radio frequency backhaul (using X-band or Ka-band links), which can limit the gateway's throughput.
