# Security and sovereignty

Security means being able to protect people, infrastructure and operations. Sovereignty concerns the ability to make and carry out decisions without unacceptable dependence on someone else. In space, these concerns overlap with communications, observation and navigation. They also extend to the ability to launch, control and protect the systems themselves.

This motivation does not describe one separate type of satellite. It changes the requirements placed on many of the same capabilities used elsewhere. A government may need a connection it can prioritise, imagery it can obtain under particular conditions, or a launch capability whose availability it can influence.

## 1. Users: who needs an assured capability?

Users include government crisis teams, defence organisations, border and maritime authorities, diplomats and satellite operators. Their missions differ. Civil disaster response and military operations should not be treated as the same purchasing process simply because both may need resilient communications.

EU GOVSATCOM identifies crisis management, surveillance and key infrastructure among its use cases. The EU Satellite Centre, SatCen, supports EU foreign and security policy through analysis using satellite imagery, aerial imagery and other information. These provide concrete examples of users seeking an operational result rather than a spacecraft for its own sake. [EUSPA: GOVSATCOM use cases](https://www.euspa.europa.eu/eu-space-programme/secure-satcom/govsatcom), [SatCen: mission and users](https://www.satcen.europa.eu/who-we-are/our-mission)

| User group | Need | Possible purchasing organisation |
|---|---|---|
| Crisis response team | Coordinate when ordinary communications are damaged or unavailable | A national authority or authorised programme |
| Government analyst | Understand a place, event or change | A government department or security institution |
| Defence organisation | Maintain communications, information and navigation for its missions | A defence procurement body or established contractor |
| Satellite operator | Understand collision risks and protect service continuity | The operator, sometimes using a public safety service |
| Public programme owner | Retain access to launch and operational capability | A state, group of states or public agency |

The buyer examples describe roles to investigate. They are not a statement that every user can procure directly or that every contract is open to a new supplier.

## 2. Needs: what does “secure” actually mean?

The word can hide several needs. **Confidentiality** means restricting who can read information. **Integrity** means protecting it against unauthorised alteration. **Availability** means being able to use the service when needed. A fourth concern is who controls access, priorities and changes to the system.

An encrypted connection can still be unavailable. Owning a satellite does not automatically remove dependencies on foreign components, launch services or software. A useful sovereignty discussion asks exactly which dependency matters, what could interrupt access and how much control is required. This is an analytical framework, not a claim that complete independence is possible or always desirable.

A government also needs to distinguish normal performance from performance during a crisis. Who receives priority if demand rises sharply? Can approved users obtain equipment quickly? Who is allowed to operate it? The programme’s requirements and actual agreements must answer those questions.

## 3. Services: what is delivered to the user?

Services can include controlled communications capacity, imagery and analysis, navigation for authorised users, collision warnings and access to launch. The outcome may be a secure connection or a report, rather than ownership of a new satellite.

GOVSATCOM is designed around pooling governmental and commercial satellite communications capacity and sharing it with authorised governmental users. That is different from assuming every user receives a dedicated spacecraft. Its access arrangements are part of the service design. The public description is evidence of the programme’s intended organisation, not a blanket guarantee of current availability for any requester. [EUSPA: how GOVSATCOM is organised](https://www.euspa.europa.eu/eu-space-programme/secure-satcom/govsatcom)

Space safety offers another concrete service. EU Space Surveillance and Tracking, or EU SST, provides collision avoidance information, re-entry analysis and fragmentation analysis. A warning service supports an operator’s decision; it does not physically move the satellite. [EU SST: services and user arrangements](https://www.eusst.eu/about-us/faq)

## 4. Systems: what sits behind those services?

A communications service needs user terminals, satellites, ground networks and operations teams. Security adds requirements for access control, protection and monitoring across that chain. The spacecraft alone cannot guarantee the protection of information handled by an insecure terminal or ground system. ENISA’s satellite communications assessment treats these interconnected components as part of the security problem. [ENISA: communications system security](https://www.enisa.europa.eu/sites/default/files/publications/LEO_satcom_cyber_security_assessment_240214.pdf)

An imagery service has a different chain: obtain suitable observations, process them, combine them with other information, analyse them and deliver an appropriate product to the authorised user. SatCen’s stated mission includes both space assets and other sources. Its service should therefore not be reduced to receiving a satellite photograph. [SatCen: imagery and related services](https://www.satcen.europa.eu/who-we-are/our-mission)

A collision-warning service uses observations of objects in space, processing and analysis, and a channel for communicating information to users. An operator then assesses its own spacecraft and operational constraints. EUSPA describes EU SST’s warning and user-interface roles. [EUSPA: EU SST](https://www.euspa.europa.eu/eu-space-programme/ssa/eu-sst)

These systems show how one motivation reaches across several layers. The user needs an assured result. Different technical chains may supply it.

## 5. Enablers: what makes access dependable?

Funding, qualified suppliers, trained staff and continuing maintenance are all necessary. So are arrangements for handling information, admitting users and accepting equipment. Procurement rules and any security requirements must be examined for the actual programme and contract. There is no single rule that makes a Belgian company eligible for every European security opportunity.

Independent launch is another enabling capability. ESA explains Europe’s Ariane effort in terms of securing independent access to space. This does not mean every European mission must use the same launcher. It explains why governments may value the option to launch without relying entirely on another country. [ESA: the origins of Ariane](https://www.esa.int/About_Us/50_years_of_ESA/Thirty_years_of_Ariane)

Cooperation remains important. NATO’s space policy recognises national control over capabilities while describing cooperation among allies. Sovereignty can therefore involve agreements and shared capabilities, not only building everything nationally. [NATO: overarching space policy](https://www.nato.int/en/about-us/official-texts-and-resources/official-texts/2019/06/27/natos-overarching-space-policy)

## Journey one: connecting a crisis response team

Imagine an authorised response organisation needs communications where a terrestrial network is unavailable. The people in the field need usable terminals and a connection to their coordination centre. The buyer needs an arrangement covering capacity, permitted users, support and priorities.

The system might draw on existing satellite capacity rather than a new satellite. Someone must deliver and configure the equipment, keep it powered, connect the local devices and support the users. The team needs to practise with it before an emergency. These are practical questions suggested by the dependency chain, not findings from an exercise observed during this research.

This journey overlaps with the communications motivation. The difference is the emphasis on controlled access, continuity and the circumstances in which the service must work. A general broadband offer and an accepted crisis service are not automatically interchangeable.

## Journey two: helping an operator assess a collision warning

An operator receives information suggesting its spacecraft may pass close to another object. Its team needs to understand the risk, assess the information and decide what action is appropriate for its mission. The useful service includes the warning and an established way to exchange relevant information.

EU SST documents configuration arrangements with users and a service portal. Its separate coordination platform has been tested with users including EUMETSAT and Avanti. This is evidence of an operational coordination task, not proof that a new paid platform is needed. [EU SST: user services](https://www.eusst.eu/about-us/faq), [EU SST: coordination platform](https://www.eusst.eu/newsroom/news/eu-sst-communication-coordination-platform-now-available)

A potential business must understand what public services and existing tools already cover before claiming a gap.

## Europe, Belgium and the direction of travel

IRIS² illustrates Europe’s pursuit of secure connectivity. In August 2026, the European Commission announced a revised implementation agreement. ESA’s programme page describes development and validation work and planned deployment. These are signs of funded implementation; they should not be presented as proof that the complete future network is already operating. Dates and architecture may change, so current programme documents matter. [European Commission: August 2026 agreement](https://defence-industry-space.ec.europa.eu/european-union-accelerating-and-reinforcing-iris2-2026-08-07_en), [ESA: IRIS² programme](https://resilience.esa.int/esa-programme-related-to-eu-secure-connectivity-and-iris%C2%B2)

For a Belgian supplier, the next step is to identify a specific buyer, contract or established partner. BELSPO is a route into understanding Belgium’s participation in European space activity. It does not replace the eligibility and acceptance conditions of the particular procurement. [BELSPO: Belgian space activities](https://www.belspo.be/belspo/space/index_en.stm)

## What to investigate as a business

**Technical:** does the capability meet its defined conditions, including relevant disruptions? **Operational:** can authorised people use and maintain it in practice? **Commercial:** is there a funded buyer and an accessible route to procurement? **Economic:** can the supplier survive development, acceptance and ongoing support costs?

Possible questions concern difficult deployment, fragmented information and dependence on scarce specialist staff. These are investigation leads. Public strategic concern is not enough to prove recurring spend on a particular solution. Ask a reachable organisation what it recently bought, which problem remains after that purchase and what conditions a new supplier would have to meet.

The central idea is: **security and sovereignty place additional demands on services across the sector; they do not occupy one isolated layer.**
