Objectives
•
Qualify micro and nanotechnology components
–
•
Qualify new sensors and boom systems
–
•
Major step forward in the technical development of
instrumentation for space science research.
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.
Space science objectives are secondary

Electric Field Vector Sensor
• 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
