Changing the economics of space
Platform
•SSTL-12
•
Flexible, modular satellite solution
With scalable architecture and a modular avionics solution, Surrey’s entry-level nanosatellite offers
power, mass, and payload capability exceeding those of other offerings in its class. The configuration
comes in a small package, but still offers high-end capabilities and performance, along with great
flexibility in payload accommodation.
The platform is compatible with various launch vehicles and is ideal for launching in batches to
enable constellations.
The SSTL-12 is suitable for missions ranging in mass from 10 to 75 kilograms. Pricing starts at $500,000.

The small satellite revolution started 30 years ago with Surrey Satellite Technology—the world’s premier provider of operational and
commercial satellite programs with 47 satellites launched successfully and 250-plus years of on-orbit operational experience gained.
From its Englewood, Colorado, facilities, Surrey supplies complete in-house design, manufacture, launch, and operation of small
satellites, to include remote sensing, navigation, and communications payloads, avionics suites and subsystems, ground infrastructure,
and training and consulting services.
