After replacing the faulty power supply of the ICARUS computer, the exchange unit has been successfully launched on December 6th and arrived at the ISS today.
It is foreseen to connect the computer to the antenna on the 16th of December and tests will resume afterwards. We are thrilled to seeing ICARUS finally in operation!

On December 4th, shipment of the second set of solar arrays for the Sentinel 6/Jason-CS Satellite B left the SpaceTech headquarters. We delivered the solar arrays to Airbus Defence and Space, where the containers arrived safely in the Airbus cleanroom. Being a milestone to the work of the joint project team, all flight hardware under STI responsibility is now delivered.

For STI, the Jason-CS is another successful solar array project that will be finished on time, on cost and -most important- on quality!

Satellite AIT and launch

The shipset for Satellite A was already delivered in April this year. The solar array was successfully mounted to the satellite structure by Airbus. Satellite A currently undergoes its environmental test campaign and is scheduled for launch end of 2020.
Satellite B is in assembly at the moment and the solar array will be mounted within the next months.

Mission details

The Jason-CS mission is part of the Copernicus program and continues the ocean topography missions started in 1992. Jason satellite altimetry data provides sea surface and wave heights for determining ocean circulation, climate change and sea-level rise. These measurements are necessary for ocean modeling, forecasting El Niño/La Niña events, and hurricane intensity prediction. The science objectives include weather, water and climate research.

 

 

Smallsat trend

The privately-owned company York Space Systems pushes forward a trend: making spaceflight affordable. Hence building the S-CLASS satellite platform that can easily adapt to customer needs at low cost. The reduction of launch costs is an important topic for the space company too, constantly developing new ideas to making space applications a real option even for smaller companies and organizations. The small satellite is powered in orbit by 4 deployable solar arrays, for which York Space Systems selected STI as supplier for the photovoltaic assemblies.

STI solar array

Speaking “the same language,” SpaceTech is always aiming for reduction of production costs and reducing lead times, using innovative techniques and thinking outside the box. The automated solar cell laydown is one of the advantages STI solar arrays gained in 2018 and has now been proved successful with the first S-CLASS platform in orbit, verifying the technology and opening the way for significantly lower solar array lead times and costs for future missions.  

Launch

The satellite was launched as the primary spacecraft on 5 May 2019 and is successfully operating in orbit since then. Remarkable: It took less than 3.5 months, from first hardware at York Space System Facilities to launch site delivery.

STI is proud to be part of this mission and looking forward to further cooperation.

 

We are proud to announce being part of the Lidar Emitter and Multispecies greenhouse gases
Observation INstrument project - short LEMON, a H2020 funded activity.
The LEMON consortium consists of 8 partners from 4 different countries, including academic experts,
research centres and SME partners.

Mission goal

LEMON shall deliver a new DIfferential Absorption Lidar (DIAL)
sensor concept in order to measure greenhouse gases
and water vapour from space and demonstrate the concept
in an airborne campaign.

LEMON features

The innovative LEMON concept is based on a versatile, efficient multispecies Lidar emitter:

  • development of only one space instrument for CO2, CH4, H2O, HDO measurements necessary
  • simultaneous CO2+H2O or H2O HDO measurements possible

SpaceTech development for LEMON

Being part of the LEMON project, STI was elected to develop, manufacture and deliver the so-called LEMON FRUIT
which consists of a wavemeter, controlling unit, tunable absolute reference laser and heterodyne beating detection.
In addition, SpaceTech is responsible for the system planning and evaluation of a future spaceborne LIDAR.
