TDS instrument

Goals /  Study of solar Type II and III radio emissions. Measurements of high-frequency electromagnetic waves in the solar wind. Detection of interplanetary dust particles.

Basic facts / TDS receiver is a part of the RPW (Radio and Plasma Waves) instrument providing multi-component electromagnetic wave measurements of frequencies up to 200 kHz. TDS digitizes four analog high-frequency channels: three components of the electric field and one component of magnetic field. The obtained signal is processed onboard by implemented algorithms. Only relevant scientific data are downlinked to Earth. The receiver was developed at the Department of Space Physics, Institute of Atmospheric Physics CAS. The RPW instrument is being developed in a consortium, lead by Observatoire de Paris, France.



Mission / Study of physical processes inside the inner heliosphere and their mapping to source regions and structure of the solar surface. Measurements of space plasma parameters, electromagnetic fields and energetic particles in the solar wind in the vicinity of the Sun.

Launch / 2020

Instrumentation /  Optical cameras and coronograph; RTG, UV and EUV detectors; electron and ion detectors, electromagnetic sensors, low- and high-frequency antennas for electric and magnetic field measurements.

Orbit / Elliptical and Heliocentric with the closest approach to the Sun at ~0.28 AU

Mission life time / 7 years (including cruise phase)
