Спутник связи. GSAT 2. [Редактировать]

GSAT-2 это 2000 кг экспериментальный коммуникационный спутник который использовался при тестовом пуске ракеты GSLV Mk.1. Спутник оснащен полезной нагрузкой C и Ku диапазона. В качестве дополнительной полезной нагрузки на аппарат установлены:

  • Монитор полной радиационной дозы TRDM (Total Radiation Dose Monitor);
  • Монитор поверхностного заряда SCM (Surface Charge Monitor);
  • Рентгеновский спектрометр солнечного излучения SOXS (Solar Xray Spectrometer);
  • Экспериментальный когерентный радиомаяк CRABEX (Coherent Radio Beacon Experiment).
