Surrey satellites are baselined from previous missions and tailored to individual customer requirements. The design and manufacture of all these elements is undertaken in-house.
Surrey follows a heritage-based design and implementation approach while at the same time providing performance matched to the mission requirements. Tried and tested units are flown alongside innovative, cutting edge units to provide the customer with the optimal mission solution, providing a reliable spacecraft that is a high-performance solution.
In line with its heritage-based approach, Surrey system product line revolves around a set of highly customizable "platforms." Inherent modularity in the design means that these can satisfy almost any mission requirement.
Flexible, modular nanosatellite 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.
||390 mm x 390 mm x 470 mm
||390 mm x 390 mm x 370 mm (expandable in the Z direction)
||Up to 45 kg
|Payload Data Interfaces
||CAN, RS485/RS422, LVDS, SpaceWire
||2 or 4 arrays (angled arrays can be set to suit a range of LTAN and inclinations)
||1 to 7 years
||12 V unregulated (upgradable to 28 V unregulated)
A single system architecture and technology designed to meet all mission applications and requirements across a range of variants.
Baselined from heritage designs, core platform services such as power, structure, processing, communications, and high-precision attitude control are scaled to meet any mission on a compact platform that includes variants and a payload-ready platform.
Current SSTL-50 mission: KazSTSat
SSTL-100 and SSTL-100+
Used in the highly successful Disaster Monitoring Constellation (DMC) the SSTL-100 provides the core capability to carry a wide range of payloads.
Active variants include SSTL-100i 32 m resolution
(first-generation DMC) and SSTL-100i 22 m resolution
Current SSTL-100 mission: AlSat-1B
Heritage SSTL-100 missions: ExactView-1,NigeriaSat-X, UK-DMC2, Deimos-1
An enhanced version of the SSTL-100 platform with substantially improved payload capacity, improved propulsion and added high-attitude agility. It is ideally suited for use of customer-supplied payloads given its straightforward interface scheme. Active variants include SSTL-150i 4 Agile (DMC-4),SSTL-150i 2.5 m resolution agile and SSTL-150 (RapidEye constellation and TechDemoSat-1).
Heritage SSTL-150 missions: TechDemoSat-1, KazEOSat-2, RapidEyes, Sapphire, CFESat
SSTL-300 & SSTL-300+
Very flexible configuration, capable of supporting a large spectrum of implementations, payloads, and structural configurations. Current variants are optimized for optical EO from 2.5 m (NigeriaSat-2) to 1 m resolutions (DMC3 constellation), SAR and science EO payloads.
NovaSAR-S Synthetic Aperture Radar
NovaSAR-S combines our heritage SSTL-300 series avionics suite with a new structure and an innovative payload, developed in collaboration with Airbus Defence and Space, that can be adapted to different frequency bands.
NovaSAR-S delivers all-weather medium-resolution Earth observation data night and day at a price similar to traditional optical missions, and significantly lower than any other SAR platform currently on the market, by leveraging highly efficient S-band solid state technology. The platform is sized for a range of low-cost launch options.
Surrey's platforms are based on a common core of avionics which are used alongside mission-specific avionics that have been developed to provide customized solutions. The high degree of modularity and flexibility used allows new developments and techniques to be readily transferred from one platform to another as demand in size or capability changes.
