4 For a successful launch. We build reliable products. RUAG Space products are chosen by today s leading launch service providers. We have equipped every Ariane rocket with payload fairings since the very first launch in 1979, and our composite structures are featured onboard American Atlas rockets. RUAG Space adapters and separation systems ensure there is a safe connection between satellite and rocket. Payload Fairings and Launcher Structures RUAG Space is the world s leading supplier of composite technology payload fairings. Payload fairings are mounted at the tip of the launch vehicle to protect the satellites during the ascent and to make the shape of the rocket more aerodynamic. RUAG Space produces the payload fairings for the European launch vehicles Ariane 5 and Vega and the American Atlas-V-500, and supplies the smaller Atlas-V-400 with the Interstage-Adapter ISA-400, a composite structure that connects the main stage and upper stage of the rocket. Our payload fairings have been used in over 220 rocket launches to date, and have never failed. Payload Adapters and Separation Systems RUAG Space is the world leader for payload adapters and separation systems used on commercial launch vehicles. Our separation systems ensure that satellite and rocket remain securely attached to one another during the tough journey into space, and then deliver the valuable payloads into orbit with precision. Our modular adapters mean that nearly all satellites can be fitted to almost every type of launcher. RUAG Space equips Antares, Ariane, Atlas, Delta, Proton, Sojus and Zenit rockets. To achieve optimum performance, payload adapters are manufactured, as required, from aluminum or carbon fiber composites. Over 495 separations have been carried out in orbit using RUAG systems, with a 100 percent success rate. Sounding Rocket Guidance RUAG Space offers a range of products for sounding rocket guidance and for sounding rocket payload attitude control. RUAG systems are also currently used by NASA for their sounding rocket projects as well as on board ESA Maxus rockets. 4 RUAG Space

6 Precise orientation in space. Precise engineering on earth. Many successful space missions are built on RUAG Space structures. And we keep things moving on board satellites, too. Our mechanisms point solar generators, thrusters, antennas and instruments in the right direction. In extreme conditions. Year after year. With the utmost precision and reliability. Satellite structures RUAG Space has equipped the majority of European satellites with lightweight, rigid and thermally stable structures. The range of missions that RUAG is involved in spans ESA science missions such as Herschel/ Planck or BepiColombo, the ATV European space transporter, and the Alphabus and SmallGeo telecommunication platforms. Depending on the requirements of each mission, we employ different technologies when developing satellite structures, from conventional aluminum elements through to monolithic or sandwich carbon fiber reinforced polymers. Special materials made from high-modulus fibers or Zerodur sandwiches are used for optical instruments and other applications that demand the highest level of temperature stability. Satellite mechanisms RUAG Space precision mechanisms are highly regarded by renowned space customers throughout the world, in particular when it comes to the precise positioning of solar generators, thrusters, antennas and instruments. We offer a broad spectrum of space-proven Solar Array Drive Mechanisms (SADMs) for solar generators to suit satellites of any size. RUAG Space has developed a variety of pointing mechanisms for electric satellite thrusters, such as those used successfully for the Artemis and Smart-1 ESA missions. The electric thruster on board BepiColombo, the ESA mission to Mercury, also features a RUAG pointing mechanism. RUAG Space develops and produces high-precision pointing and scanning mechanisms for positioning scientific instruments and for optical communications. Slip rings RUAG Space is the leading manufacturer of slip rings for space applications worldwide. Our reliable slip rings are at the heart of many mechanisms on board satellites, and they are also in demand for challenging applications outside the field of space travel and exploration. Mechanical ground support equipment RUAG Space provides Mechanical and Electrical Ground Support Equipment (MGSE and EGSE) for satellite integration, transportation and testing, for instance providing trolleys for integration and special containers for transporting sensitive satellites. Thermal Systems RUAG Space multi-layer insulation offers satellites reliable and effective protection from the extreme temperatures in outer space. RUAG s cryogenic superinsulation is also used on Earth for various applications including helium liquefiers and superconducting magnets. 6 RUAG Space

8 Because there is no help desk in space. Digital electronics you can rely on. RUAG Space supplies radiation-resistant and fault-tolerant computers to ensure that rockets make it into space safely and that the various systems on board satellites work together seamlessly, year after year. Our navigation receivers are able to determine a satellite s orbital position to the nearest centimeter. Computers for satellites and launchers RUAG Space guidance and control computers have piloted more than 200 Ariane rockets safely into space. The high resistance to radiation, robust, fault-tolerant design and high error detection coverage of these computers ensures maximum reliability on the journey into space. RUAG computers monitor and control various subsystems on board satellites just as reliably, performing a plethora of remote control and data transfer functions. They prepare data for transmission to Earth and carry out instructions issued to the satellite from the ground. They control satellites on-board power distribution and temperatures, and execute actions such as the pyrotechnic release of locking mechanisms after satellites have been deployed in space. RUAG computers have successfully controlled over 80 satellite missions to date, and have proven their reliability with an impressive cumulative track record of more than 600 years of in-orbit operation. Navigation receivers and signal processing RUAG Space s GPS Precise Orbit Determination (POD) receivers can determine a satellite s position in orbit around the Earth to within a few centimeters. This high-precision system is primarily used to collate the measurements collected by Earth observation satellites so that they are exactly geographically accurate. RUAG Space delivers complete POD systems including antennas that are able to process both the older GPS signals and the new L2c signal. The next-generation devices will also be compatible with Galileo, the new European navigation system. RUAG Space also builds specialized navigation receivers for use on board weather satellites. These GPS radio occultation receivers measure the way signals from navigation satellites are altered as they pass through the Earth s atmosphere. This can be used to derive information about atmospheric water content and temperature. RUAG Space develops and builds signal processing units for Earth monitoring and science satellites that are tailored to the specific requirements of each particular mission. 8 RUAG Space

10 Connecting the world is essential. We help satellites communicate. RUAG Space products on board telecommunications satellites keep people connected all around the globe. And RUAG Space technology is often involved when it comes to maintaining contact with satellites in Earth orbit or probes far out in space. Receivers and converters RUAG has already supplied more than 1,000 receivers and converters for telecommunication satellites of globally renowned customers. Our microwave units cover UHF to Ka-band frequencies, are small in size and characterized by low noise, high linearity and excellent frequency stability. It is not only the technical properties of our products that lead many commercial satellite missions to select RUAG Space as their partner of choice, but also our short delivery times, strict awareness of costs and superb customer service. Antennas RUAG Space is one of the world s leading suppliers of satellite antennas. Our portfolio of products includes reflector antennas, wide coverage antennas and array antennas. RUAG Space reflector antennas range in diameter from 0.4 to 3.3 m, and span frequency ranges from S band through to 575 Ghz. Our reflector antennas are characteristically low in mass, have great temperature stability and high surface accuracy. RUAG s wide coverage antennas are used to transmit control commands or telemetry data to and from satellites or launch vehicles. We have a comprehensive range of space-proven antennas, and develop tailor-made products to suit specialized mission requirements. RUAG Space array antennas are especially suitable for telecommunications use, positioning or for space radars. RUAG is the technological leader in the design of slotted waveguide arrays. Optical communication RUAG Space has developed a series of products for optical communication in space that cover a range of applications, from satellite missions in orbit around the Earth through to deep space communication. Optical communication with laser beams is a compelling alternative to radio waves when it comes to transmitting large quantities of data over long distances through space. High data rates combined with little power consumption and low payload weight make laser communication terminals particularly appealing for use on board satellites. 10 RUAG Space

12 Because scientists need accurate data. Our instruments collect them. In collaborative projects with scientific institutes and universities, RUAG Space has built some of the most sophisticated scientific space instruments and experiments ever invented. In cooperation with the University of Berne, Switzerland, for instance, RUAG Space built a spectrometer for ESA s Rosetta comet probe, currently on its way to the comet 67P/Churyumov-Gerasimenko. Rosetta is due to enter orbit around the comet in the year 2014, after which the instrument will examine the composition of the comet s thin atmosphere. RUAG Space is also currently working with the University of Berne to develop Bela, the BepiColombo Laser Altimeter for ESA s BepiColombo mission to Mercury, the planet nearest the sun. Bela will use laser beams to create a three dimensional map of the planet s surface. But RUAG Space instruments do more than just explore distant heavenly bodies: they also provide valuable information that benefits us all in our day-to-day lives. Take the weather forecast, for example. RUAG Space supplied the Gras instruments (GPS Receiver for Atmospheric Sounding) used in the MetOp polar orbiting European weather satellites. Gras instruments measure water content and temperature in the troposphere and stratosphere. Two RUAG Space spectrometers on board ESA s ADM-Aeolus wind research satellite will help expand what we know about the Earth s atmosphere. Data from ADM-Aeolus will not only help make weather forecasts more accurate, it will also help us to better understand global warming. Radiation monitors developed by RUAG Space, such as those on board the European Galileo satellites, also help us explore and monitor space. The term space weather is used to describe changes in environmental conditions near to the Earth, and above all refers to the influence on the Earth s magnetic field of solar wind. Radiation in space is not just a threat to satellites and astronauts; modern electronic systems on Earth can be influenced or even destroyed by space weather, too. RUAG Space builds miniaturized bioreactors for zero-gravity research that are used to carry out long-term biological and medical experiments such as the cultivation of yeast, animal or plant cells. 12 RUAG Space
