• Qualify micro and nanotechnology components – Major step forward in the technical development of
instrumentation for space science research.
• Qualify new sensors and boom systems– Shrinking the electronics is not sufficient, sensors
and boom systems must also follow suit.
• Test and verify new measurement methods– New questions in space science, inspires the need
to find new measurement methods.
Objectives
Jan Bergman
Space science objectives are secondaryBremen, March 22 – 24, 2005
• Unique capabilities– Dynamic 3D E-field vector, up
to 20 MHz– Unambiguous 3D wave
polarization characteristics– Statistical properties, such as
wave entropy, can be derived • Major challenge
– Amount of Signal processing capabilities versus spacecraft heat and power requirements
– Three different digital implementations are studied
• Low mass– 1000 mm long extendible
antenna, 2.7 gram
Electric Field Vector Sensor
Jan Bergman Bremen, March 22 – 24, 2005
Langmuir Probe
• Unique Capability– Plasma density, n, and temperature, T, from DC to 10 kHz– Digital signal generator makes it possible to measure local
temperature (up to 10 kHz)– Ion masses can be derived
• Dual probe experiment– Simultanous measurements of electrons and ions– Interferometry– Tests of two different probe surface coatings (BepiColombo)
• Low mass– 273 mm long deployable boom, 0.7 gram 5 mm Titanium probe, 0.3 gram
Jan Bergman Bremen, March 22 – 24, 2005
Anisotropic magnetoResistive Magnetometer• Unique Capabilities
– 3D magnetic field vector, B, from DC to 10 kHz• Small size and low mass
– Volume 4×8×3.8 mm3
– One gram for the whole instrument• Extremely interesting technology for future
satellite and Lunar missions– Frequencies up to 7 MHz– Bad sensitivity 5-10 nT
• Prototype AMR sensors aquire 0.1 nT sensitivity• Prototype Spin Dependent Tunneling (SDT) sensors < 1 pT
• Mounting on a solar panel frame
Jan Bergman Bremen, March 22 – 24, 2005
FluxGate Magnetometer• Unique Capabilities
– 3D magnetic field vector, B, from DC to 100 Hz
• Major challenge– Miniaturization of the sensor
• Maximum mass 10 g• Maximum volume 20× 20× 20 mm3
– Possibilities to involve a partner are being investigated
• Mounting on a solar panel frame
Jan Bergman Bremen, March 22 – 24, 2005
Antennas & Booms
• Six 1000 mm extendible EFVS antennas– Metal foil antennas– Low mass and smooth release
• Antenna element 2.7 gram (Titanium)• Release mechanism 20 gram
• Two 273 mm deployable rigid LP booms– New boom design with a bellow hinge– Low mass and smooth release
• Boom 0.7 gram• Release mechanism 10 gram
