Satellites & Platforms
Building and operating the hardware layer in orbit.
Launch Services
56Companies that develop and operate orbital launch vehicles to deliver payloads to space. Revenue comes from selling launch as a service. Includes dedicated missions and rideshare.
Suborbital & High-Altitude
17Companies operating vehicles that reach space altitude without achieving orbit, or that operate in the stratosphere. Includes suborbital rockets, high-altitude balloons, and stratospheric platforms.
Space Transportation & Logistics
45In-space transfer vehicles, orbital tugs, and cargo systems. Companies that move payloads between orbits or deliver them to specific destinations after separation from a launch vehicle.
Spaceports & Range Services
14Operators of launch sites, landing zones, range services, and associated ground infrastructure that enables launch and reentry operations.
Satellite Communications
93Companies that operate constellations or individual satellites to provide connectivity: broadband, mobile backhaul, IoT, direct-to-device, broadcast, or relay services.
Earth Observation & Remote Sensing
81Companies that operate satellites to capture data about Earth's surface, atmosphere, or oceans. Includes optical, radar, thermal, multispectral, hyperspectral, and RF sensing.
Navigation & Positioning
24Companies developing satellite-based positioning, navigation, and timing (PNT) systems or augmentation services beyond government-operated GPS/Galileo/GLONASS.
Satellite Manufacturing
107Companies that design and build complete satellite systems or buses for other operators. Prime integrators and platform providers. Distinct from component suppliers.
Satellite Components & Subsystems
103Manufacturers of specific satellite hardware sold to integrators: solar arrays, antennas, reaction wheels, star trackers, power systems, thermal management, structures, deployables.
Space Propulsion
73Companies developing propulsion systems sold as products to other spacecraft or launch vehicle builders. Electric, chemical, nuclear, or novel propulsion technologies.
Space Sustainability & Debris Removal
16Active debris removal, end-of-life deorbit services, debris mitigation technologies, and compliance solutions. Companies whose primary mission is keeping orbits usable.
In-Orbit Servicing & Assembly
29On-orbit inspection, repair, refueling, life extension, repositioning, or construction. Servicing existing assets rather than removing debris.
Space Domain Awareness
38Tracking objects in orbit, monitoring the space environment, characterizing threats, providing space traffic data, collision avoidance services, and RF interference detection. Encompasses both physical tracking (SSA) and strategic/behavioral context (SDA).
Space Stations & Habitats
10Developing crewed or uncrewed orbital platforms for long-duration occupation. Commercial stations, modules, and habitable structures.
In-Space Manufacturing
29Manufacturing in microgravity or vacuum. Includes pharmaceutical processing, fiber optics, semiconductor crystals, bioprinting, and materials science.
Lunar Services
18Landers, surface systems, rovers, habitats, communication relays, and navigation services for the Moon. Companies building the lunar economy.
Planetary Exploration
14Systems for Mars, Venus, asteroids, or outer solar system destinations. Probes, rovers, sample return, and deep-space transportation.
Space Resources & Mining
6Prospecting, extraction, and processing of natural resources from celestial bodies. Water ice, regolith, metals from asteroids or the Moon.
Geospatial Intelligence & Analytics
51Processing, analyzing, and deriving insights from satellite-collected data. The software layer above Earth observation hardware. AI/ML applied to imagery and signals.
Space Software & Mission Tools
68Mission planning, orbit determination, flight dynamics, satellite operations software, digital twins, and simulation platforms for the space industry.
Ground Segment & Networks
65Ground station networks, satellite-as-a-service platforms, managed ground operations, antenna farms, user terminals, GNSS receivers, modems, and terrestrial connectivity infrastructure for space assets. Includes both ground station operators and ground equipment manufacturers.
Space Tourism & Experience
3Spaceflight experiences for private individuals. Orbital, suborbital, high-altitude, and analogue/training experiences.
Crew Systems & Life Support
4Spacesuits, EVA equipment, environmental control and life support systems (ECLSS), radiation protection, and human factors technologies.
Space Defense Systems
46Missile warning, space control, protected communications, responsive launch, counter-space capabilities, and space-based defense platforms.
Space Intelligence & Reconnaissance
10Space-based ISR (intelligence, surveillance, reconnaissance) primarily for government and defense. Includes SIGINT, GEOINT, and ELINT from orbit.
Space Cybersecurity
5Cybersecurity solutions for space systems. Satellite cyber hardening, quantum key distribution, zero-trust architectures for ground-to-space links, post-quantum cryptography for space communications, and space segment resilience against cyber threats.
