Satellite Bus Comparison

The most-flown GEO commercial satellite bus in history with over 120 spacecraft delivered. Pioneered all-electric orbit raising for GEO missions. Supports the largest commercial broadband payloads including the 9,200 kg Jupiter-3, the heaviest commercial communications satellite ever launched.

Boeing's flagship large GEO bus, available in high-power (702HP) and small platform (702SP) variants. The 702SP pioneered all-electric GEO satellites. Used for the largest broadband missions and is the platform for the O3b mPOWER MEO constellation.

One of the most prolific GEO satellite buses ever built with unmatched military heritage. The backbone of U.S. military protected communications and GPS navigation. Being superseded by the modernized LM 2100 for new programs.

Purpose-built for the Space Development Agency's proliferated LEO constellation architecture. Designed for mass production with emphasis on rapid delivery and low recurring cost per unit.

Ball Aerospace's smallest standard bus, designed for rapid-build small satellite missions. Compact form factor with high reliability heritage from government science and technology demonstration programs.

A step up from BCP-100, the BCP-Small family bridges the gap between micro and medium satellites. Proven on NASA science missions and commercial Earth observation.

ESPA-class bus designed to ride as a secondary payload on ESPA rings, reducing launch costs. Ideal for responsive space and SDA proliferated LEO architecture.

Airbus's next-generation GEO communications platform offering 50% more payload capacity than Eurostar E3000. Supports all-electric or hybrid propulsion configurations. Modular design enables rapid customization for broadband, broadcast, and government missions.

Northrop Grumman's GEO-optimized medium bus. Provides a smaller GEO platform option for missions that don't require the capacity of full-size GEO buses.

Northrop Grumman's proven LEO science platform. Known for reliability and precision pointing for NASA astrophysics and Earth science missions.

Modernized evolution of the A2100 bus, used extensively for military and civil government missions. Highly modular with a strong track record on GPS navigation satellites and protected communications.

Maxar's LEO Earth observation bus designed for the WorldView Legion constellation. Extremely agile with rapid target revisit. Represents Maxar's pivot from GEO-only to LEO constellation operations.

Airbus's fully software-defined, reconfigurable GEO platform. Payload coverage, capacity, and frequency can be dynamically adjusted in orbit. Standardized production line targets 50% cost reduction and 30% shorter delivery times versus bespoke GEO satellites.

Thales' next-generation GEO platform offering full flexibility between chemical, all-electric, and hybrid propulsion. 40% lighter than Spacebus 4000 thanks to composite structures. Supports both commercial broadband and military communications payloads.

Surrey's workhorse small satellite platform, widely used for Earth observation and technology demonstration. Offers excellent performance-to-cost ratio with rapid delivery timelines, typically 18-24 months.

Enhanced small satellite platform from SSTL supporting sub-meter imaging payloads. Offers high agility for multi-target imaging in a single pass with rapid slewing capability.

Terran Orbital's configurable small satellite bus optimized for constellation deployment. High-rate production facility can deliver multiple units per month with standardized interfaces.

Blue Canyon's highly modular bus family spanning XB-1 (6U CubeSat class) through XB-16 (ESPA-class). The most scalable small satellite platform on the market, with configurations for everything from CubeSat-scale science to ESPA-class tactical missions.
