parties, especially in the frame of Multimedia Terminals and equipment.

• A team of highly qualified engineers and managers with experience in

their fields of expertise are responsible for the company's activities from

research and development up to production and marketing.

• ATTISAT has experience in the design and procurement of moulding

production tools for injection and thermoforming plastics and of metal

tooling.

• Should the market needs dictate, ATTISAT is capable of casting and

forming using specific CAD s/w for the mechanical design of the pieces and

the tools.

• It is also capable of setting up a production line for flat and parabolic

antennas or other passive microwave component in a very short time.

PRODUCTION

• ATTTISAT is involved in the initial design of the products, prototype

implementation and testing.

• ATTISAT's personnel and associates have an accumulated experience of

over 25 years and expertise in space telecommunications and microwave

engineering. They have been involved in a large number of projects at

national, European and international level.

RESEARCH AND DEVELOPMENT

Example projects are: • Design and implementation of various flat antennas from L-band to Ka-band.

• Design of a GaAs FET low noise amplifier for satellite applications.

• Design and implementation of microwave filters for the 25 MHz - 30 GHz,

frequency band.

• Design of typical wireless apparatus; e.g., RF front-end amplifiers, up/down

converters,passive microwave components, CDMA Detectors etc.

• Wireless digital communications MODEM performance evaluation and

development.

• Simulation of digital satellite channels.

• Design and implementation of VSAT subsystems and networks.

• Design and implementation of digital satellite modems.

PRODUCTION • ATTISAT's production line incorporates the manufacturing equipment,

production flow and control.

• The manufacturing equipment includes a number of moulding, casting,

thermoforming, cutting and press tools.

• Production control involves the inspection of performance, validation,

capacity level determination and resource monitoring.

• In order to conform to strict specifications and maintain a high quality

level, production testing is carefully conducted.

• The assembly line involves the use of electric tools, production line testing

equipment and packaging equipment. • Production capacity is up to 40.000 planar antennas per year or 100.000 units

per for other type of antennas

• CAD software for microwave and millimeter wave components design and

simulation

• Proprietary software for antenna design and analysis

DEMONSTRATION CENTER

An advanced Demonstration Centre has been developed by ATTISAT S.A at its premises

enabling the Demonstration of various satellite applications like Two-Way satellite

communications, TVRO reception etc.

• Due to their small size and environmentally friendly shape, planar antennas

are attractive for DTH satellite TV reception (ASTRA, EUTELSAT,

HELLASSAT etc.) in areas where the installation of bulky conventional

parobolas is not permitted.

• The main advantage of ATTISAT's proprietary design is that it leads to a

high performance, high quality flat antenna that can be produced in large

quantities at a relatively low cost.

• ATTISAT flat antennas incorporate an optimum combination of radiating

elements and printed circuits within an ergonomic and environmentally

friendly construction.

• Based on ATTISAT's design, technologically advanced transmitting and

receiving flat antennas, with a relatively small size can be developed for

applications such as, mobile telecommunications, LMDS, MMDS,etc.

THE FL500 ANTENNA

• ATTISAT FL500 antenna presents high interference

rejection from neighbouring satellites and exceptional

cross-polarisation discrimination (<-30 dB).

• Due to its small size and mass plus its elegant design, it

can easily be installed on the balcony, in the garden or

the roof, suiting naturally with the environment.

• Attisat S.A offers an impressive range of designs thus

transforming an antenna into a decorative element.

• Due to their very low profile ATTISAT FL500 antenna

is an excellent solution for satellite TVRO systems in

mobile platforms (caravans, vehicles etc.)

• ATTISAT's personnel are experienced in the design and installation of VSAT

point-to-multipoint networks. They have designed and set up the first Satellite

Network for Seismic Data collection in Greece.

• Working in close cooperation with its clients, ATTISAT provides Turn-Key

Satellite Communication solutions for Data, Voice, Video distribution. Its

activities include the design, procurement, installation and maintenance of Civil

and Governmental satellite earth stations for DVB Audio/Video distribution and

complete SCPC networks.

• Being one of the partners of the HOST project the company has been involved

in the early phase of the development of the HELLAS-SAT Net DVB-RCS

network responsible for the Pilot Sites installation and maintenance in Greece,

Albania, Serbia, Morocco and Tunis.
