System Architecture of KOMPSAT-5

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

Imaging modes

The KOMPSAT-5 can be acquired in three observation mode.
Observation modes with one polarization selectable among HH, VV, HV, or VH
High Resolution mode
high-resolution mode collected over a small area by steering the
radar beam slightly fore-to-aft during
the collection period.

[ 1 meter GSD, 5km Swath width ]
Standard mode
a medium-resolution mode collected over long,
continuous swaths in which the beam is pointed broadside
to the satellite track.

[ 3 meter GSD, 30km Swath width ]
Wide Swath mode
a low-resolution mode that creates extra-wide swaths by collecting short segments at different ranges and then mosaicking them together.

[ 20 meter GSD, 100km Swath width ]
