Space technology
Space Business became a part of DA-Design in 2007 with the merging of DA-Design & Ylinen. DA-Design carries out projects as a subcontractor for major space companies and European Space Agency ESA. Typically these projects include system and equipment design, manufacturing and testing. DA-Design makes subsystems into satellites and performs technology development for the future satellites.
New facilities enable space quality equipment manufacturing for both electrical and mechanical parts. Assembly and testing is done in a purpose built clean room facility. Measurements are mainly carried out in DA-Design in-house facilities with a possibility to test in a nominal space environment, vacuum. The clean room area contains all needed measurement equipment and simulation of space vacuum and temperatures down to +4 ˚K.
Projects:
Huygens radar altimeters, end customer European Space Agency ESA
- ESA / NASA mission to study Saturn. ESA probe Huygens landed on the moon Titan and made studies on the atmosphere and the surface of the moon during the landing phase. The two redundant radars gave altitude information for timing of landing and measurements. The return signal was also used to model the structure of the titan surface.
- 119 GHz receiver is used to measure molecular oxygen (O2) spectral line. Odin satellite studies both upper layers of atmosphere and interstellar media.
- These are very stable and accurate signal distribution units to divide transmit signals and combine receive signals in the SAR (Synthetic Aperture Radar) satellites. Satellites produce high resolution 3D images of the surface of the earth. The data is used to follow land usage and to predict and follow nature catastrophes.
Planck receivers, end customer European Space Agency ESA
- 70 GHz receivers are cooled to 20 K enabling a world's best overall recover sensitivity between 25 K & 30 K over a 14 GHz bandwidth. Planck receivers measure Cosmic Microwave Background (CMB) radiation originating from Big Bang. Study of CMB anisotropy maps will provide invaluable help to cosmologists in determining the mechanisms operating during the Big Bang creation event.
- Calibration subsystems for 1.4 GHz synthetic aperture radiometer system. SMOS satellite is used to measure Soil Moisture and Ocean Salinity.
Sentinel-1 SAR transmitter and receiver microwave subsystems, end customer European Space Agency ESA
- Several subsystems for this 5.4 GHz SAR-satellite having similar type of usage as TerraSAR-X and TanDEM-X satellites.
