TWTs Market Trends (1)

Market needs per TWT families

L-band• Medium power (up to 140W RC, 170W CC)• High power CC : EM to prepare GPSIII

S-band• High power RC : high priority for radio broadcasting (qualification)• Very High power (300-500W) to fit with Digital Audio System needs (the today

solution is several tubes in parallel)

C-band• Improved performances (30-120W CC) : +3% efficiency• Reduced manufacturing cost


TWTs Market Trends (2)

Market needs per TWT families

Ku-band• Medium power (up to 160W RC/CC) : improved performances (efficiency, gain

variation,…)• High power (150-220W class) : improved performances• Flexible TWT

Ka-band• Medium power (up to 130W) : improved technical performances• High power (130-200W) : to maintain similar performances as for 130W TWT

class• Flexible TWT

Development

Example of 3 Special Developments:

Space TWTs for Navigation

Tubes with flexible Power adjustment

Diversification - HEMP


L- Band TWT

L- -Band TWTs

- available between 80 and 230 W- cover the typical Navigation frequency range from 1.1 to 1.6 GHz- Compatible to navigation requirements- Space heritage by Worldstar/ MTSAT and Giova A


L-Band TWTA for Giova A

Picture of theGIOVE SatelliteTWTA

One Amplifier coverthe whole Navigation Band from 1,1 to 1,58 Ghz with one setting


In Orbit Flexibility

Concept:

TWT with optimised flexible helix line

EPC with adjustable Anode voltage

Linearsier and Camp for optimal frequency and gain adjustment

Anode adjustment by telemetry from ground

Benefit:

Allow performance adjustment in orbit for the individual application

Flexible to any upcoming new application within the life time

Flexible to adapt to the needed traffic for a special application


In Orbit Flexibility

Actual Status at TED

2 programs in Ku band running under Artes 3(German TWT and in France LCTWTA - until begin 07)

1 program in Ka-band with Tesat (until end 06)– possible use in Hylas Program

measurements available in L-/S-and C-band

Anode adjustment independent from Frequency

Strong interest from Customer side

HEMP 3050 Ion Thrusters

A new thruster concept has verified its potential for LEO, MEO and GEO satellites and scientific mission applications: orbit topping, north/south station keeping (NSSK), drag compensation, repositioning, de-orbiting of small (0.5 t) to large (10 t) satellites, deep space cruising.

Thrust & power range: 1 mN to 80 mN at 20 W to 2 kW withSpecific Impulse 1500 s to 3000 s (exhaust velocity: 15 to 30 km/s)

80% to 90% of propellant mass saving compared to chemical thrusters

Reliable and long life operation due to magnetic plasma confinement: Erosion free operation for more than 18.000 h or a total impulseof more than 4.106 Ns.Light bulb like turn on & turn off procedures allowing automaticattitude and orbit control (AOCS) routines similar to chemical thrusters.

Clustering of modular thrusters: Allows thust vectoring and avoids a mechanical gimbal mechanism (cost cutting).

Simple power supply and flow control unit interfaces: 50% cost cutting possible compared to standard Hall Effect EP system.
