STI contracted for LISA Laser EM development

The Laser Interferometer Space Antenna (LISA) mission, will be the first space-based gravitational wave observatory. Based on fundamental theories of gravitation, it will detect and observe gravitational waves that are emitted when powerful events in the universe happen.

In a consortium of SpaceTech, Ferdinand Braun Institute Berlin, Fraunhofer ILT, Airbus Defence & Space, DELOS and DLR Bremen, STI demonstrated the required laser head performance in the laboratory on breadboard units. 

After successful completion of phase 1, ESA selected the consortium under STI to develop the Engineering Model (EM) of the LISA laser head. Instead of the ECDL seed laser applied in phase 1, the seed laser concept of LISA pathfinder was selected by ESA for the continuation of the development due to schedule and development risk considerations.

We welcome TESAT within our consortium!

SpaceTech selected to deliver ICU for ROSE-L & CESS for CRISTAL

On July 1st 2020 ESA approved the procurement of the 6 upcoming “High priority candidate missions (HPCM)” of the ESA Copernicus program. Within their HPCM proposal Airbus selected STI to develop and build the Instrument Control Unit (ICU) for the Radar Observing System for Europe mission ROSE-L as well as the Coarse Earth Sun Sensor (CESS) for Copernicus Polar Ice and Snow Topography Altimeter mission CRISTAL.

The ICU development will be SpaceTech’s first “stand-alone” electronics unit to fly on an ESA mission and is an important milestone for STI electronics equipment. STI electronics are already regularly included in our various payload activities.
It also marks the second use of the advanced CESS, providing significantly improved performance over the original CESS, which is in orbit on more than 15 missions.

OneWeb Satellites for global internet: STI production of solar array deployment mechanisms is back on track

We are happy to announce that SpaceTech’s solar array deployment mechanism production for Airbus OneWeb Satellites is back on track. After a 6-months pause caused by OneWeb filing for chapter 11 this spring and successful acquisition by the UK government and Bharti Global, we restarted the production of the deployment mechanisms for Airbus Oneweb Satellites.

We are – once again - excited to be part of the OneWeb story for global internet – and more.


York Space Systems orders 10 solar arrays from SpaceTech

After a record-setting “in-orbit delivery” of the first STI solar array for York Space Systems, the company has placed another order with STI to deliver 10 solar arrays for several satellite contracts.

SpaceTech space solar arrays YORK SPACE SYSTEMSYork Space Systems makes spaceflight more affordable, pushing the smallsat trend in the new space market. York was founded to radically improve spacecraft affordability and reliability and is leading the industry in transforming and enabling next generation space mission operations worldwide. We are proud to be part of this success story.

Having a contract with a new customer for the first time is great. Being selected for further contracts after a successful mission is even more valuable to us. This is especially true as the first solar array we delivered to York is the first solar array flying with our fully automated PVA laydown process, laying the foundation for a whole range of recently acquired contracts.

About York Space Systems

York Space Systems was founded to radically improve spacecraft affordability and reliability and is leading the industry in transforming and enabling next generation space mission operations worldwide. York specializes in purpose-driven customer solutions and the rapid production of mission-ready spacecraft platforms. York’s complete Space Segment Solution including spacecraft production, payload integration, system integration and test, launch services, ground segment services, and mission operations enables customers to leverage York’s existing technology solutions to rapidly and responsively get to orbit outpacing competitors. York’s S-CLASS industrial-grade platform is a standardized 3-axis stabilized spacecraft capable of supporting 85kg payloads with up to 3,500W peak (enhanced power system), while reducing the cost of manufacture by an order of magnitude. The S-CLASS spacecraft is fully compatible with all launch vehicles, including ground and air-launched, and ground segment providers. When optioned with York’s cloud-based mission tasking and operations center, an ultra-low-cost solution is available on demand for next generation data collection and analytics companies.
