Product Detail

KOMPSAT-5 provided X-band SAR (Integrated Aperture Radar) images to the world market in 2014

Mission – The main mission objective of KOMPSAT-5 system is to provide the following applications (Gold Mission) :

Geographic information system

Marine management

Land management

Disaster monitoring

Environmental monitoring


KOMPSAT-5 was launched on August 22, 2013.


Dawn/dusk stationary orbit, altitude 550km, tilt Angle 97.06°, period 95.78 minutes. The Local Time on Ascending Node (LTAN) is 6:00 a.m.

KOMPSAT-5 System architecture

The KOMPSAT-5 system consists of a space segment, a ground segment, a launch segment, and various external interfaces including additional external ground stations to support the launch as well as the early orbit phase and the normal operation phase.

Imaging mode

KOMPSAT-5 can obtain data in three observation modes. Single polarization observation mode: HH or VV or HV or VH.

High resolution mode

During the acquisition, the radar beam is adjusted slightly in the forward and backward direction to acquire high-resolution data in a small area. (1-meter ground resolution, 5km bandwidth)

Standard mode (middle mode)

Continuous strip data acquisition for satellite flight orbit lateral. (3-meter ground resolution,30km bandwidth)

Wide mode (low score mode)

By imaging the distance to subsets of different ranges and stitching, ultra-wide bands of low-score data are formed for data acquisition. (20 m ground range resolution, 100km bandwidth)

The launch time is August 22, 2013
