Zond

Zond [NPP VNIIEM]

Zond is a solar observation satellite developed by for Roskosmos for the project Ionozond.

The space segment of project Ionozond includes consists of four Ionosfera and one Zond satellite. The constellation of Ionosfera satellites is designed for the operational monitoring of the magnetosphere and ionosphere, while Zond measures the solar irradiadion.

The sun pointed satellite weights 390 kg and is built for an 8 years orbital life. The spacecraft uses APPT-95M Ablative Pulse Plasma Thruster (APPT) for orbit correction propulsion system.

Zond will carry following instruments:

  • The telescope-coronagraph (STEK) is designed to monitor the solar corona at altitudes of between 1 and 10 solar radii in the spectral range of vacuum ultraviolet (VUV) and visible regions of the spectrum in order to detect and determine the dynamics of coronal mass ejections (CMEs).
  • Sun imaging spectral telescope "SOLIST" is designed to measure the radiation fluxes and building high-precision images of the transition layer and the solar corona in the range of heights from 0.05 to 1 solar radius.
  • Spectrophotometer X-ray (RESPEKT) is designed for continuous monitoring of X-ray flux of the solar corona.
  • X-ray photometer (SRF) is designed to measure the X-ray radiation from the sun on a background of charged particles.
  • Spectrophotometer stream sun's ultraviolet radiation (SUF) is designed to measure the flux of solar radiation in the resonance lines of hydrogen HLa (121,6 nm).
  • Multispectral system for UV, visible and IR camera "Letizia" is intended to measure the spatial distribution of the radiation intensity of lines of 630 nm [OI], 427,8 nm [N2 +] upper atmosphere and ionosphere.
  • Scanning Ozonometer-W is designed for spectroscopic measurements of the Earth's atmosphere the intensity of reflected UV radiation from the sun in the band 300 to 400 nm.
  • Magnetometer (FM-G) is designed to measure the three components of the magnetic induction of the magnetic field of the Earth in order to conduct an operational global and continuous monitoring of the spatial and temporal distribution of the magnetic field in the near-Earth space.
  • RF mass spectrometer (RIMS-A) is designed for automatic analysis of neutral and ionic composition of the upper atmosphere of the Earth's atmosphere and its own satellites in two ranges of mass numbers (1 - 4) and (10 - 50) atomic mass units (AU m.).
  • Gamma-ray Spectrometer (SG/2) is designed to measure the differential energy spectra of hard X-ray and gamma-ray radiation from the sun in the energy range (0,02-10,0) MeV.
  • Low-frequency wave complex (NVK2) is designed to measure magnetic and electric fields of near-Earth space in the frequency range from 0 to 20 kHz in order to determine the state of the magnetosphere-ionosphere plasma and identifying the influence of natural and anthropogenic origin.
  • Board control and collection of scientific information (BKUSNI-E) for the collection, storage and transmission of target information devices in the radio RLTSI-I, as well as for operation control unit CCA.
