SSTL satellites are baselined from previous missions and tailored to individual customer requirements. The design and manufacture of all these elements is undertaken in-house.

SSTL 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, SSTL system product line revolves around a set of highly customisable "platforms". Inherent modularity in the design means that these can satisfy almost any mission requirement.

SSTL-100
Used in the highly successful Disaster Monitoring Constellation (DMC) which has achieved more than 10 years in-orbit heritage. The SSTL-100 provides the core capability to carry a wide range of payloads. Active variants include SSTL-100i 32 (1st generation DMC) and SSTL-100i 22 (2nd generation DMC).

SSTL-150
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 (Beijing-1),SSTL-150i 2.5 Agile and SSTL-150 RapidEye.

SSTL-300
The natural evolution of the SSTL-150 platform, designed for highly demanding applications. Very flexible configuration, capable of supporting a large spectrum of implementations, payloads and structural configurations. Current variants are optimised for optical EO (from 2.5m to sub 1m resolutions), SAR and science EO payloads. Active variants include SSTL-300i 2.5 Agile, SSTL-300i 1.0 Agile, SSTL-300i UHR, SSTL-300L and SSTL-300r.

SSTL-900
Versatile, low cost communications, navigation and exploration platform. The SSTL-900 is designed for MEO, GEO, HEO and interplanetary orbits. Flight heritage achieved as Europe’s first Galileo satellite, GIOVE-A.

Customised Platforms
SSTL's platforms are based on a common core of avionics which are used alongside mission specific avionics that have been developed to provide customised 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.
