Wave complex KEM-3
The wave complex KEM-3 is designed to measure the parameters of
electromagnetic waves in the VLF and ULF ranges. It measures one
component of the electric field and three components of the magnetic
The electric antenna is a 1.6 m long dipole made up by two
spherical carbon EDS detectors each with a preamplifier. The
detectors are fixed at the ends of the folding booms of
The magnetic component is measured in two ranges: ULF (1 Hz -
2kHz) and VLF (1 - 50 kHz). The MSU detector of the ULF range
is located on the folding arm of the subsatellite. Its antennas
a research-coil detectors with low-noise preamplifiers. The
same detector is also used for the VLF device. The one-component
MSV detector of the VLF range is a search-coil detector
with a preamplifier and is located on another folding boom.
The output signal of the detectors either is processed by the
device electronics for transmitting the wave form by means of analog
telemetry, or the amplitude of spectral lines is transmitted by
means of digital telemetry. The amplitude obtained either in the
VLS filter unit or in the step spectrum analyzer SAS.
The frequency range and sensitivity are the following:
