Galileo Navigation Payloads

We have already delivered 22 navigation payloads for the deployment phase of Galileo, Europe's satellite navigation system and are now under contract to build a further 12 payloads.

OHB System AG is the prime contractor and builder of the spacecraft platform and SSTL has full responsibility for the navigation payloads, the brains of Galileo's navigation system.


We are supplying a small geostationary satellite platform for the first “EUTELSAT QUANTUM” class telecommunications spacecraft, due to launch in 2019.  We are under contract to prime contractor, Airbus Defence and Space, who are supplying the flexible payload for the spacecraft.  

EUTELSAT QUANTUM will be our first geostationary satellite platform and the design is based on the SSTL VAMP satellite product, a small and scaleable geostationary craft. 

The new spacecraft design will represent a first in the commercial satellite industry, by enabling the complete electronic synthesis of “receive” and “transmit” coverages in the Ku-band. 

ELSA-d Target

We are supplying a "Target" satellite and avionics for ASTROSCALE's inaugral ELSA-d mission, which will simulate capture of orbital debris and is designed to validate key technologies for end-of-life spacecraft retrieval and disposal services.  

The ELSA-d mission comprises of a "Chaser" satellite and the Target satellite, and will demonstrate key technologies necessary for orbital debris removal such as rendezvous and docking and proximity operations.  ASTROSCALE are designing and manufacturing the Chaser in Tokyo using avionics from SSTL.

We have supplied 6 spacecraft platforms for the FORMOSAT-7/COSMIC-2 Program, a joint constellation meteorological satellite mission between Taiwan and the United States for observing and monitoring the global meteorology, climate, and ionosphere. The goal of the joint program is to establish an operational constellation  to replace the current FORMOSAT-3/COSMIC mission.

Orbital Test Bed (OTB)

The Orbital Test Bed (OTB) satellite will carry five demonstration payloads for a variety of commercial, US government, and academic organisations. With the assistance of the Department of Defense Space Test Program, OTB is scheduled to launch on the SpaceX Falcon Heavy.
