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
12Artes 11 Small GEO Workshop: Tegernsee 29.-30. June 2006
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

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.
