Our linearizers are used in high-speed data transmission systems such as satellite communications, the Internet, and 4K / 3D television, enabling broadband use of high power and system amplifier frequencies in information transmission, and are thus an integral part of forward-looking data transmission with the highest signal quality.
The optimization of the amplifier characteristics enables ideal power utilization and leads to energy savings of more than 50 percent. Thus, linearizers may be referred to as a ""green product"" which enables the use of low cost, compact power amplifiers. Astyx engineers have years of experience developing and manufacturing linearizer modules. Our products are individually adapted to the respective amplifier types and customer requirements. We supply linearizers for the frequency bands C-, X-, Ku-, DBS-, Ka- and tri-band (C-, X-, Ku-band combined).
With the "Atomic Clock Ensemble in Space" mission (ACES), the two organizations ESA (European Space Agency) and the French Space Agency are expanding the research scope of the International Space Station (ISS).
The mission's goal is to create a comparable time scale for Earth-based atomic clocks using two space-based atomic clocks called the PHARAO (Project of Horloge Atomic) and SHM (Space H-Maser) , In this project, Astyx supplies microwave components (hybrids) for signal transmission from the space station ISS to ground level.
The hybrids are used in the transmitter and receiver and, for frequency generation in the so-called "Microwave Link" (MWL). The components work in the Ku band and S band frequency ranges (13.5 - 14.7 and 2.2 GHz, respectively) and have been certified for space travel in cooperation with Astrium and ESA.
Astyx has made a name for itself as a leading systems supplier for the development and manufacture of innovative 77GHz radar systems for automotive environment perception. We work with OEMs and automotive suppliers to provide solutions for future requirements in advanced radar sensor technology.
Based on the Astyx radar technology, we develop radar solutions for environment detection in the aerospace sector for helicopters as well as for UAVs.
Whether in flight or on the ground, our Digital Beamforming (DBF) technology is particularly well suited for the robust requirements of this segment in assisting the aircraft to detect obstacles in difficult weather conditions.
Autonomous and semi-autonomous systems are increasingly finding their way into the industrial sector. Based on the Astyx radar technology and in cooperation with our customers, we develop sensor solutions for these applications, particularly in the field of environmental sensors for the industry of tomorrow.
In offshore drilling for oil production, Riser Tensioner cylinders are used as a stabilization system for drillships and platforms. The modern Direct Acting Tensioner cylinders guarantee a predefined tension of the drill string and compensate for all movements of the drillship, e.g. from sea swell and fluctuating waves. The system consists of six hydraulic cylinders mounted directly between the riser on one side and the derrick on the other side. Alternatively, the combination wire-line tensioner and drill string compensator is used. All three types of cylinders require a displacement measuring system in order to be able to compensate for the movement of the drillship in a controlled manner. The Astyx microwave sensor (ATEX Zone 1 certified) is ideally suited for harsh conditions at sea.
Currently, only nitrogen on the antenna side is used as operating medium. The following diameters can currently be delivered:
E-field in a pneumatic cylinder
Pneumatic drives are considered to be a cost effective actuator technology, e.g. to be able to approach controlled positions in robotics. For this purpose, distance measuring systems are required. Our patented displacement measuring system for pneumatic cylinders has the following properties:
