Mission Platforms
 
 

 

Flexible, modular, cost-effective small satellite platform

The Swift is based on Surrey’s heritage systems with experience derived from dozens of successful missions. Optimized for high-performance missions ranging from 5 to 7 years in low-Earth orbit (500 to 1000 kilometers), the Swift is versatile and cost-effective, with scalable architecture and modular avionics solutions. 

The Swift typically ranges in mass from 3 to 400 kilograms and can accommodate a wide range of mission requirements.  

Swift’s versatility enables missions employing a single platform or constellation. Its volume-efficient packaging and dimensions offer the option of a simultaneous launch of multiple platforms.

The smallest of Surrey’s platforms is the Swift Nano, suitable for missions ranging in mass from just 3 kilograms. This configuration comes in a small package, but still offers high-end capabilities and performance, along with flexibility in payload accommodation.  The Swift Nano is perfect for demonstration missions, low-cost constellations, and high-performance missions in an LEO environment. The Swift Nano includes conventional platform build classes such as cubesats and nanosatellites.
