IndustryAtlasSUPPLY CHAIN HANDBOOK
Satellite connectivity combines constellation operations, launch, payloads and ground equipment. Start with service delivery, then trace the hardware supporting it; component makers and service operators deliver different things.
Launch completes only part of deployment. Payloads, gateways, user terminals and constellation management must work together to connect space links with terrestrial networks. Satellite manufacturers deliver spacecraft suited to launch and orbital conditions. Operators manage network capacity and connectivity; service integrators handle customer access and support. Satellite counts, available capacity and paying users are therefore related but distinct measures of progress.
Antennas, RF and processing perform the mission, while the bus supplies power, pointing and thermal functions. Integration verifies their operation within shared mass, power and interface limits.
Launch services manage vehicle interfaces, integration and separation. Checkout and subsequent deployment remain necessary before a satellite joins the operating network.
Terminals provide user access and gateways connect terrestrial networks. Operators and service providers coordinate capacity, equipment and support; customers may procure an integrated service rather than space hardware.
Separate space hardware from ground terminals before comparing suppliers. Both may contain RF components and PCBs, but their environments, power, tracking and maintenance constraints differ.
The LEO communications chain includes constellation operation, service integration, satellite manufacturing, launch, ground stations and user terminals. Start with who operates the network and delivers the service, then follow the hardware and material requirements.

A communications satellite combines the payload performing the communications mission with a platform supplying power, attitude control and environmental support. Satellite integration verifies that subsystems operate together under launch and orbital conditions.
The platform provides shared support while the payload performs the mission. Available power and thermal capacity constrain the communications equipment.
Spaceborne boards and ground terminals can use different components and qualification approaches. Terminal shipments cannot be counted directly as satellite demand.
Distinction: A satellite platform alone is not a communications service. Launch, ground networks, terminals and continuing operation are also required.
Examples of complete-satellite manufacturing and platform integration; component and subsystem suppliers are identified under their respective roles.
Eutelsat publicly commissioned Airbus to manufacture satellites for OneWeb constellation expansion.

Launch involves transportation, satellite-to-vehicle interfaces, integration testing and separation. Reaching an initial orbit is followed by spacecraft checks and further deployment before satellites can enter service.
Launch integrators coordinate documentation, testing and payload interfaces. Transport, ground handling and launch environments also matter.
After deployment, teams verify spacecraft status, establish communications and join constellation operations.
Distinction: A rideshare launch does not guarantee direct delivery to every required final orbital position. Deployment depends on the mission.
Launch is the service of placing satellites in orbit. Development, test launches and commercial orbital-launch records should be verified separately.
Develops small-satellite launch vehicles and launch-service capabilities.

Ground systems include traffic gateways, terrestrial-network connections and tracking, telemetry and control functions. Different sites and systems can perform these roles; they are not all one antenna.
Antennas, RF equipment, modems and network devices jointly support operation. Commercial broadband gateways and scientific mission stations have different traffic needs.
As terminals track successive satellites, the network must coordinate paths and resources. Specific handover strategies depend on the constellation and equipment.
Distinction: A gateway is not the satellite antenna at each user location. It handles traffic between satellites and terrestrial networks.
This topic covers hardware and its components; ground-network operators appear in a separate service topic.
Microwave passive components for ground stations; network operations are listed separately under ground-station network services.

A user terminal typically combines antennas, RF, data processing and power, then connects to a router or existing network. Similar-looking equipment can support different constellations and use cases.
Antennas and RF front ends handle the wireless link; modems and processors handle signals; boards, power and mechanics integrate the functions.
Calibration, cooling, installation, repair and cost all influence terminal design. Antenna and control boards may need different materials.
Distinction: A flat antenna panel is not a complete terminal. Transmission, reception, processing, power and network connections also matter.

Ground-network providers use owned or partner stations for tracking, telemetry, control and data reception. Operators can outsource this work or build their own stations. Operating a station network differs from manufacturing antennas and RF hardware.
Equipment includes antennas, RF and data-processing hardware. A service provides station time, connection scheduling and operational support.
Satellite control, data downlink and broadband gateways have different link requirements.
Distinction: A ground-service example does not establish that it serves every LEO constellation or operates every broadband gateway.

LEO communications must follow moving satellites. Mechanical antennas change physical direction; phased arrays control beams through element phase or amplitude. Application, size, performance and cost determine the approach.
Antenna arrays work with RF channels, power amplifiers, low-noise amplifiers and control circuits. Exact integration depends on the design.
Satellites, gateways and user terminals all use antennas under different constraints. Compare frequency band, scan range, gain and power together.
Distinction: Not every LEO terminal uses a phased array. Mechanical tracking and multiple-panel approaches also exist.
Solutions use electronic scanning or mechanical tracking; the antenna itself is also distinct from a complete terminal.

Satellite communication uses power and low-noise amplifiers, frequency converters and beamforming circuits, together with digital processing, memory and power management. Spaceborne and ground equipment require separate component selection.
Ground terminals often emphasize cost, cooling and volume production. Space equipment also considers orbital conditions, mission lifetime and fault tolerance.
Amplifiers must work with antennas, boards, power and thermal design. Reference designs explain functions without establishing a universal production configuration.
Distinction: Satellite-related chips are not all space-grade, and spaceborne requirements cannot all be met by general commercial ground components.
Foundry services and chip brands are different roles; ground-terminal ICs are not automatically suitable for space.

Satellite communications uses payload and control boards in space, RF boards in gateways, and antenna or main boards in user terminals. This is an application grouping, not a new fabrication technology separate from multilayer, HDI or rigid-flex.
PCB makers fabricate circuits from materials supplied in different resin, reinforcement and copper combinations. RF examples include PTFE and hydrocarbon/ceramic routes, selected for the frequency and process.
Low-loss figures depend on measurement conditions; finished boards also depend on traces, vias, copper surfaces and assembly.
Distinction: A LEO PCB is not one material specification. Satellite and ground-terminal requirements must be distinguished.
Space-payload, ground-station and user-terminal boards face different environments and qualifications; general PCB capabilities do not establish space-grade supply.
