STI development

SpaceTech developed the JASON-CS solar array that consists of four solar panels, two are body mounted and two are deployable. STI got under contract with Airbus in 2016 and was able to design, produce, test and deliver within 36 months.


Being an international partnership between the U.S. and Europe, Jason Continuity of Service (Jason-CS) mission on the Sentinel-6 spacecraft will deliver valuable information about sea level change to all nations.
The mission is designed to ensure continuous observation of the earth sea level for a minimum of 10 years.
Global sea level rise is one of the most important impacts of human-caused climate change. The first JASON-CS satellite will be launched in 2020, followed by a second one in 2025. The data generated by the two satellites will be used to improve forecasts of weather conditions two to four weeks ahead. This system will be able to forecast hurricane intensity and other irregularly occurring weather conditions like El Niño even for the next season.

No longer just a dream: Internet for everyone everywhere - Airbus OneWeb Satellites (AOS) is aiming for global broadband internet. The AOS mega constellation will consist of 900 small satellites. AOS selected SpaceTech to develop and deliver the 1800 solar array deployment mechanisms.

STI development

SpaceTech was able to provide Airbus OneWeb Satellites with a QM development of only three months and already delivered the Solar Array Deployment Mechanism (SADM) flight hardware for the pilot satellites that have been built at Airbus OneWeb Satellites (Toulouse site, France).
The launch of six pilot satellites took place February 27th, 2019 and the solar arrays deployed successfully.  Based on this, AOS contracted SpaceTech for the SADMs for the full constellation, 1800 deployment mechanisms – two on every satellite.
Delivering these key parts to make the project a success, SpaceTech proves once again its suitability for the New Space Market with utmost flexibility and cost-efficency. SpaceTech is proud to being part of this exciting project. Thanks to all of the project partners for the great team work.

STI cleanroom deployment test solar array Jason-CS

March 18th, 2019, STI headquarters: The deployment tests of the solar array of the JASON-CS flight model have been performed flawlessly at the STI cleanroom facility under ESA supervision. With this successful demonstration STI concludes the mechanical verification of the solar array for the first satellite.
This is an important milestone towards delivery of the hardware to Airbus, scheduled for April 2019.

Mission goal

The Jason-CS mission is part of the Copernicus Space Component and is developed by ESA under the GMES Space Component Segment 3 (GSC-3) program. The main objective of the Jason-CS/Sentinel 6 mission is to provide a long-term availability of high precision ocean surface topography observations in support of Copernicus services.


The launch of the first spacecraft is planned for 2020.
