Technology that sets the highest standards

Satellite Communication

Key Technology of Global Communication

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 linearizers are designed for use in ground station applications. 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).

Transmit and receive modules

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.

Industry sensors

Cylinder Position Sensing

We make cylinders intelligent:

  • Next Generation Position Sensing
  • Measurement of piston position with microwaves
  • Additional data acquisition for efficient maintenance of the cylinder
    • Pressure and temperature acquisition
    • Logbook function with recording of the total travelled distance, operating hours, strokes, number of load cycles, min/max pressure and temperature, etc.
    • Increased reliability of the sensor due to permanent self-monitoring
  • Features:
    • Absolute distance measurement
    • No dead zones: the complete stroke will be captured
    • X-length capable (stroke lengths over 7,500 mm possible)
    • Scalable to every cylinder diameter
    • No need for gun-drilling of the piston rod
    • Flexible integration with internal or external electronics
    • Replacement of the electronics possible without dismounting/disassembly of the cylinder
    • No moving parts and therefore no abrasion
    • Various customer interfaces: Analog: voltage and current interface, digital: CAN-Bus, Profibus, RS485 etc.
  • Technology works with hydraulic and pneumatic cylinders

Offshore sensors

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:

    Riser Tensioner:

  •         360 mm with Zone 2 antenna (customer interface: power interface)
  •         480 mm with Zone 2 antenna (customer interface: power interface)
  •         560 mm with zone 2 or zone 1 antenna (customer interface: Profibus)
