KOMPSAT-2
Question 1
Into what general category of EOS does the instrument fall?
Multispectral and panchromatic
Question 2
What capture technology is used?
Scanning
Question 3
Is the sensor active or passive?
Passive
Question 4
At what wavelength(s) does the sensor function?
Pan : 500 - 900 nm
MS1 (blue) : 450 – 520 nm
MS2 (green) : 520 – 600 nm
MS3 (red) : 630 – 690 nm
MS4 (near-infrared) : 760 – 900 nm
Question 5
What resolution does the sensor have – temporal and spatial?
Temporal
Orbital period of 28 days
Revisit rate of 3 days with roll angle of 30°
Spatial
KOMPSAT-2 acquires imagery in black and white (Pan) at a resolution of 1 m and in colour (MS) across 4 bands in the visible (red, green, blue) and near-infrared at a resolution of 4 m. Simultaneous acquisition of Pan and MS images means that merged 1-m images are available as a standard product.
KOMPSAT-2 images cover a footprint of 15 km x 15 km.
Question 6
Is the sensor carried on an airborne or spaceborne platform? What is that platform – typically?
The sensor is carried on a space borne platform. The platform & instrument are called KOMPSAT-2
Question 7
Who developed/launched/manages the sensor?
The sensor was developed by KARI (Korea Aerospace Research Institute). It was launched by Eurokat launch services GMBH of Bremen, Germany. It is also managed by KARI.
Question 8
Can data be purchased from service providers?
Yes - Data can be purchased at SPOT Imagery Fr
Question 9
What products are available?
1m resolution Pan imagery
4m colour imagery
Both unrectified and rectified available
Question 10
At which main application areas is the sensor aimed?
The main applications of the sensor are:
*It provides surveillance of large-scale disasters and the acquisition of high-resolution images for GIS.
*Composition of printed maps and digital maps for domestic and over-seas territories.
*Balanced development of Korean territories.
*Survey of natural resources.
*Continuation of EO after kompsat 1.
List 2 specific projects, where they have been reported, their goals and their outcomes.
Project 1 The kompsat 2 Structural Thermal Model (STM) undertook two separation shock tests on the 7th and 8th of May 2003 at KARI in Daejon, South Korea. Goals To measure the separation system induced shocks at various locations on the satellite. Outcomes The mission was a success.
Project 2 Electrical interference verification test on the 23rd of January 2004. Goals 1) To simulate the launch vehicle telemetry, to receive the data from the spacecraft. 2) To simulate the spacecraft monitors, in order to verify the status of kompsat 2. 3) To validate the software. Outcomes The mission was a success, with all the goals completed.
