Low-frequency analyser (NCHA Instrument), Consist of the following sensors:
- three orthogonal sensors measuring electromagnetic field's magnetic components,
- two orthogonal sensors measuring plasma currents,
- a pair of electric potential sensors measuring electromagnetic field's electric component,
- a three axis flux-gate magnetometer,
and a unit of spectral analysis. Sensors are placed on a boom ~ 2 m far from the satellite body.
Measured parameters:
- Electric field:
- ULF range: from DC to 100 Hz;
- VLF range: from DC to 40 kHz;
- Magnetic field:
- ULF range: 3 components from DC to 100Hz;
- VLF range: 3 components from 1Hz to 40 kHz;
- Plasma current:
- VLF range: 2 components from 1 Hz to 40 kHz.
