Kitsat 3 (Uribyol 3)

Kitsat 3

Kitsat (Korean Institute of Technology Satellite 3), renamed on orbit as Uribyol 3, was the first Korean satellite in true sense was launched by an Indian PSLV-G (2) rocket in May 1999.

The purpose of the mission was:

  • to design a satellite system that satisfies the reauirements of low cost, low power, and small size
  • to develope a satellite having 3-axis attitude control
  • to observe space environment changes in relation to solar activity
  • to provide scientific data for space science

The satellite's bus system was designed and developed by the SaTReC. The KITSAT-3 payload, MEIS(Multi-spectral Earth Imaging System), attracted international attection by its outstanding performance(13.5 m resolution), which provides image quality comparable that of large satellites.

The payloads consisted of:

  • Payloads Multispectral Earth Imaging System (MEIS)
  • Space ENvironment Scientific Experiment (SENSE)
    • High Energy Particle Telescope (HEPT)
    • Radiation Effect on Micro-Electronics (REME)
    • Electron Temperature Probe (ETP)
    • Scientific Magnetometer (SMAG)
