Ground infrastructure is entering a redesign phase as operators seek flexibility, scale, and software control to match fast-growing space capacity. At the heart of this transition are modular digital ground networks, which blend proven RF subsystems with Digital IF (DIF) and IP transport so sites can be reconfigured in software, expanded in stages, and integrated with cloud and automation tooling.

The driver is complexity: multi-orbit operations, higher frequency bands (including Q/V), and denser carrier plans are hard to manage with fixed hardware topologies alone. A modular approach standardises building blocks—frequency converters, RF-over-fibre, matrices, amplifiers and BUCs—then layers digital modules that virtualise routing, monitoring, and spectrum management. Hot-swappable units and common chassis shorten maintenance windows, while software policies orchestrate band, beam, and site changes without truck rolls.

For TV Broadcasting, this means resilient contribution and distribution paths that can fail over between gateways or orbits while maintaining signal integrity. For Infrastructure and IoT, deterministic, compact payloads can be ingested at the edge, moved over IP without RF degradation, and handed to applications with lower latency and clearer observability. As sites adopt Digital IF, they can backhaul over standard networks, enabling distributed architectures and sovereign deployments where data residency matters.

Migration will be incremental. Most estates are hybrid—large installed bases of analogue RF with selective insertion of digital modules. The practical path is “piece-by-piece” upgrades: start with monitoring/telemetry over IP, add digital switching for specific bands or missions, then extend DIF across the chain as budgets and programmes allow. Containerised or rack-mount kits accelerate greenfield builds and refresh cycles, while modular AIT (assembly, integration, test) practices compress time-to-service.

Cyber and compliance pressures reinforce the shift. Software-defined control planes centralise audit trails, role-based access, and incident response aligned to NIS2-style regimes, while cleaner signal chains improve spectrum hygiene and interference resolution. With more satellites launching than ground sites can traditionally absorb, modularity is how operators keep pace—scaling ports, carriers and sites without wholesale redesigns.

The next generation of ground players will couple RF engineering depth with software, cloud, and automation excellence—treating the ground as an adaptable platform, not a fixed plant. Those who standardise interfaces, simplify upgrades, and orchestrate across sites will set the pace—proof that modular digital ground networks are no longer optional, but essential.

How Startups Are Rethinking the Satellite Value Chain

A new wave of manufacturers is challenging legacy assumptions about how spacecraft are designed, procured, assembled, and certified. The common thread is agility: modular platforms, software-defined payload control, and hyper-local assembly to meet sovereignty and export constraints—hallmarks of startup satellite manufacturing models. Instead of betting everything on single “megafactory” scale, many challengers argue for distributed, CapEx-light facilities closer to customers, with digital pipelines that let fleets be configured, tested, and delivered at tempo.

This approach prizes optionality. Sovereign programmes want control of suppliers, data paths, and where processing occurs; commercial buyers want time-to-orbit and predictable economics. In response, builders are de-risking hardware with proven supply chains while differentiating through software, system architecture, and integration know-how. Mobile clean-room concepts—containerised AIT suites that roll to the customer site—compress logistics, enable country-of-origin assurances, and accelerate acceptance without waiting for national AIT centres to come online.

Modularity extends on orbit. Service-ready buses with compartmentalised interiors let multiple components or hosted payloads be demonstrated simultaneously, reducing non-recurring engineering and speeding flight heritage for new entrants (including non-space suppliers). Some manufacturers abstain from component fabrication entirely, acting as orchestrators: they own the software backbone, define interfaces, and curate vendor stacks to match mission, budget, and compliance needs—earth observation, secure links, or hybrid comms.

Economically, startups are also reframing GEO and LEO roles. Where broadcast and sovereign, secure connectivity have intrinsic GEO advantages, small GEO platforms and high-gain, multi-beam antennas aim to close business cases with far lower mass and power. Elsewhere, LEO remains compelling for latency-sensitive services; the manufacturing innovation is about producing the lowest-cost, fit-for-purpose “bit” per mission—without locking buyers into one orbit, payload, or factory.

For buyers in TV Broadcasting and Infrastructure and IoT, the payoff is tangible: faster time-to-service, clearer audit and chain-of-custody, and supply optionality across borders. Add in agile in-orbit demonstration pipelines, and the path from lab to operations shortens. Financing also benefits from standardised interfaces and sovereign-ready documentation that tame programme risk. As demand broadens, the winners will be those who treat manufacturing as a configurable service—proof that the future belongs to startup satellite manufacturing models.

EU Space Act compliance: what space businesses must plan

Europe is preparing a comprehensive rulebook for space that will reshape how services are licensed, traded, secured and sustained. At the core is EU Space Act compliance, a framework that seeks a single market while allowing Member States limited room for stricter measures where objectively necessary. Providers established in the EU will obtain authorisation from national authorities under common criteria, while third-country operators will need Commission registration to deliver services within the Union.

The Act also restricts engagement with third-country launch providers unless they are registered, the third country is recognised as equivalent, or a derogation applies. In practice, equivalence certificates would mirror GDPR-style adequacy, nudging international regimes toward EU standards. Cross-border players should expect dual-track obligations: home-state licences plus EU market-access conditions until equivalence is granted. Expect guidance notes and templates to follow.

Sustainability moves from guidance to enforceable duty. Operators must calculate their environmental footprint and meet binding requirements on trackability, collision avoidance, manoeuvrability, orbit selection and debris mitigation. For Aviation, this raises assurance for air-safety data relayed via satellites. For Infrastructure and IoT, it improves predictability for sensor fleets that depend on resilient constellations and clean orbital neighbourhoods.

Cybersecurity aligns with NIS2 across governance, risk and incident reporting. Fragmented national interpretations to date mean businesses should map where they are deemed “main establishment” and organise reporting lines accordingly. Enforcement will bite: the Commission may levy fines up to twice illicit profit, twice losses avoided, or 2% of global turnover for serious breaches.

The investment story is equally material. By reducing regulatory fragmentation and defining a transparent access regime, the Act aims to de-risk capital for European programmes and suppliers. A consultation phase is expected before the law is finalised; most provisions apply from 1 January 2030, with certain obligations deferred for SMEs. Now is the time to run a licensing and compliance gap analysis, refresh supplier and launch contracts, codify debris and cyber controls, and plan incident-response and audit pathways. Teams that prepare early will navigate approvals faster, protect continuity across borders, and attract partners who value certainty—practical advantages that flow directly from EU Space Act compliance.

Tracking Antennas Strengthen European Ground Segment

Three new tracking antennas are under construction at a Greek teleport, adding capacity and resilience to a third-generation mobile satellite system. As part of a wider roll-out, these tracking antennas for global gateways form the backbone of an expanded ground segment designed to improve availability, handovers, and latency for users in remote and high-demand regions.

The new builds accompany previously installed six-metre systems at the same site and are paired with upgraded power, backhaul, and control infrastructure. Together, they will support a programme to deploy up to ninety tracking antennas across roughly thirty-five gateways worldwide, underpinning network growth, redundancy, and regulatory flexibility across multiple jurisdictions.

Located at a long-established teleport in Nemea, Greece, the build adds to earlier six-metre installations completed under a hosting agreement first signed in 2020. The site provides robust grid power, diverse fibre backhaul, and favourable horizons, making it well suited to precision tracking operations.

Functionally, tracking antennas provide precise spacecraft acquisition, telemetry, command, ranging, and carrier monitoring, while routing user traffic into terrestrial networks. Increasing their number raises the probability of clear sky paths, improves load balancing during peak windows, and shortens recovery times when weather or maintenance affects service.

For industry verticals, more ground coverage translates into practical gains. Maritime operators benefit from steadier backhaul for safety, crew welfare, and cargo data on blue-water routes. Infrastructure and IoT deployments gain more predictable airtime for SCADA, smart metering, and environmental telemetry, particularly where power budgets and duty cycles are tight.

The programme also supports emergency communications. Additional gateways enable alternative routing during outages, strengthening continuity for disaster assessment teams and public agencies. In parallel, modernised monitoring allows better interference detection and faster fault isolation, protecting service quality as user numbers grow.

Looking ahead, the combination of more antennas, more gateways, and smarter control software creates a denser, more adaptable ground fabric. That fabric is essential to scaling capacity without compromising reliability, accelerating time-to-service for new regions, and enabling future services such as direct-to-device messaging and hybrid LEO–GEO routing. In short, building tracking antennas for global gateways is a pragmatic path to faster, steadier satellite connectivity.
