ACCESS MISSION DATA

KOMPSAT-2 (Korea Multi-Purpose Satellite-2), also known as Arirang-2, was developed by KARI (Korea Aerospace Research Institute) to continue the observation programme of the KOMPSAT-1 mission.

About KOMPSAT-2

KOMPSAT-2 (also known as Arirang-2) was an Earth-imaging/environmental Korean satellite which launched on 28 July 2006 and remains operational.

 Mission Specifications
Orbit Height 685 km
Orbit Type Sun-synchronous Circular Polar
Repeat Cycle 14 days

KOMPSAT-2 Objectives

KOMPSAT-2 is designed for very-high-resolution (VHR) remote-sensing applications:

  • land planning: to detect and identify features smaller than 1 sq.m., e.g. vehicles, street furnishings, roads and bushes
  • agriculture: to pinpoint crop or tree diseases
  • urban planning and demographics: to locate detached houses
  • defence: to describe high-value assets or military sites
  • civil engineering: to plan road, railroad and oil pipeline corridors
  • surveillance of large scale disasters and their countermeasures
  • acquisition of independent high resolution images for GIS
  • composition of printed maps and digitized image maps on domestic and overseas territories to users
  • continue to support satellite Earth observation activities that were served by KOMPSAT-1
