KOMPSAT-2 satellite Information

The KOMPSAT-2 system allows the acquisition of PAN images at spatial resolution of 1 meter and MS images of 4 meters from space. The mission objectives of the KOMPSAT-2 System are to provide the following capabilities in the field of earth observation

Mission

KOMPSAT-2 was developed by KARI (Korea Aerospace Research Institute) to continue the observation program of the KOMPSAT-1 mission. The main mission objectives of the KOMPSAT-2 ate provide a surveillance capability for large-scale disasters by acquiring high-resolution imagery for GIS (Geographic Information Systems) application.
Launch

The KOMPSAT-2 spacecraft was launched on July 28, 2006 (UTC).

Orbit

Sun-synchronous circular orbit, altitude 685 km, inclination 98.13º, period 98.46 min, the mean local time of the ascending node is at 10:50 hours. Repeat cycle is 28 days.

Imaging performance

The system is equipped with a solid state recorder to record images not less than 1,000km long at the end of life. The satellite fulfills drift and jitter accuracy requirements. The maximum LOS (LOS) drift will be 0.005 deg/sec and the maximum LOS jitter will be 0.4 micro-radians over 4.7 milliseconds. The satellite can be rolled up to ±30 degrees off-nadir to pre-position the MSC swath.
