Meteor-M no.1
| [Overview] [SKL] [MSGI] [PolarCaps] [FTP archive] [Charts] [Maps] [2dplots] |
Purpose
Global observation of the Earth's atmosphere and surface, allowing to systematically obtain hydrometeorological and heliogeophysical information at planetary scale.
Among other instruments Meteor-M no.1 carries the heliogeophysical hardware package GGAK-M, which brings six a wide range of emission detection instruments to a single platform. These include SGMTD, MIP, DAS-4 and DAS-1 (2 differently directed instruments each). This creates a powerful system for detecting proton and electron fluxes in the near-Earth space.
1. The MSGI-MKA spectrometer is used to measure the following parameters:
- Differential energetic spectra of low-energy electrons (0.05 - 20.0 keV)
- Electron flux density with tuned out proton background in the tens of keV to several MeV range.
- Proton flux density with tuned out electron background in the hundreds of keV to hundreds of MeV range.
MSGI-MKA is built as a single block comprised of two identical units. At any moment only one unit is operating, while the second one is in cold stanby mode.
2. SKL-MKA is used to measure the following parameters:
- Electron flux density with tuned out proton background in the hundreds of keV to several MeV range.
- Proton flux density with tuned out electron background in the hundreds of keV to hundreds of MeV range.
SKL-MKA is built as a single block comprised of two identical units. At any moment only one unit is operating, while the second one is in cold stanby mode.
Z axis is directed from the center of the Earth to the satellite,
X axis is directed as tangential velocity vector
