The ULF instrument for measuring electric and magnetic fields
in the ULF frequency range is designed for collecting and processing
information on 3 components of magnetic field and one component of
electric field. The instrument provides the analog and digital
processing of the magnetic and electric field signals through the
telemetry system (STS).
Three-component magnetic sensor is a component of the
instrument KEM (Czech Republic).
Main characteristics of the instrument:
