KOMPSAT-3
KOMPSAT-3 (also referred to as Arirang-3), the sub-meter optical satellite of the Korea Aerospace Research Institute (KARI), was established in the year 2004 as a continuation of the preceding KOMPSAT-1 and KOMPSAT-2 missions, and on May 17, 2012, the KOMPSAT-3 satellite was successfully launched using the H-IIA system from the Tanegashima Space Center, located in Japan. This mission was primarily funded by the Ministry of Education, Science, and Technology (MEST) within the Korean government's space development program.
With 0.5 meter resolution for panchromatic and 2-meter resolution for multispectral data (Red, Green, Blue, and Near InfraRed), KOMPSAT-3 is best for agricultural applications, land and urban planning, natural disasters management, geological monitoring, and bathymetry. 14 bits/pixel simplifies the interpretation of targets under shadow and classification accuracy. KOMPSAT-3 has a revisit rate of 3 days.

FAQs
There are currently KOMPSAT-2, 3, and 3A in terms of electro-optical satellites. They observe the earth about 15 times a day in low earth orbit and collect high-resolution image data used for public safety, national land and resource management, and disaster monitoring.
For Archive imagery, the minimum order size is 25km² with a minimum area width of 5km.
For Tasking, the minimum order size is 100km² with a minimum area width of 5km.
When there is cloud coverage over the area of interest during the ordered tasking window, the image collection cannot be guaranteed. However, for Standard Tasking, if the acquisition is not completed during the collection window, the tasking shall be canceled automatically. Also, for Priority Tasking, if the acquisition cannot be completed during the collection window, you can either change the priority to Standard or update the collection window to continue the acquisition. For Priority Plus Tasking, there is no guarantee for cloud coverage.
