ISRO successfully launch XPoSat Satellite

Indian Space Research Organisation’s (ISRO) PSLV-C58 has launched XPOSAT Satellite into an Eastward low inclination orbit on January 01, 2024 09:10 Hrs IST.

After injection of XPOSAT, the PS4 stage will be re-started twice to reduce the orbit into 350 km circular orbit to maintain in 3-axis stabilized mode for Orbital Platform (OP) experiments.

The PSLV Orbital Experimental Module-3 (POEM-3) experiment will be executed meeting the objective of 10 identified payloads, supplied by ISRO and IN-SPACe.

ISRO is the national space agency of India.

It operates as the primary research and development arm of the Department of Space, which is directly overseen by the Prime Minister of India.

About XPoSat Satellite

XPoSat (X-ray Polarimeter Satellite) is the first dedicated scientific satellite from ISRO to carry out research in space-based polarisation measurements of X-ray emission from celestial sources.

Noteworthy, the Satellite configuration is modified from the IMS-2 bus platform.

The Configuration of the mainframe systems are derived based on the heritage of IRS satellites.

It carries two payloads namely POLIX (Polarimeter Instrument in X-rays) and XSPECT (X-ray Spectroscopy and Timing).

To be noted that POLIX is realized by Raman Research Institute and XSPECT is by Space Astronomy Group of URSC.

The objectives of this mission are:

  • To measure polarisation of X-rays in the energy band 8-30keV emanating from about 50 potential cosmic sources through Thomson Scattering by POLIX payload.
  • To carry out long term spectral and temporal studies of cosmic X-ray sources in the energy band 0.8-15keV by XSPECT payload.
  • To carry out polarisation and spectroscopic measurements of X-ray emissions from cosmic sources by POLIX and XSPECT payloads respectively in the common energy band.
