Imaging Sensor System (AEISS), the payload of the KOMPSAT-3, provides a 0.7 m spatial resolution image and is widely used for producing precise maps because it allows stereo imaging on the same orbit. Meanwhile, the KOMPSAT-3A is almost the same as the KOMPSAT-3, but its operating altitude is 528 km, which is lower than the KOMPSAT-3 (685 km). However, the spatial resolution was improved by 0.55 m. In addition, the KOMPSAT-3A is additionally equipped with a mid-infrared sensor capable of acquiring an image with a spatial resolution of 5.5 m, and imaging is possible even at night. Sub-meter high-resolution satellite images such as those from the KOMPSAT-3/3A can accurately detect various changes including precise map production.
The KOMPSAT-5 is Korea's first synthetic-aperture radar (SAR) satellite. The KOMPSAT-5 provides X-band SAR images and provides 1 m (high resolution), 3 m (standard), and 20 m (wide swath) images depending on the imaging mode. The KOMPSAT-5 can be very useful in disaster situations such as flooding, earthquakes, and marine oil spills. Table 1 compares the sample images of the KOMPSAT series and also explains the simple satellite specifications. The KOMPSAT-3 is the successor satellite of the KOMPSAT-2 and was developed for continuous high-precision Earth observation image acquisition. The Advanced Earth Imaging Sensor System (AEISS), the payload of the KOMPSAT-3, provides a 0.7 m spatial resolution image and is widely used for producing precise maps because it allows stereo imaging on the same orbit.
