Inertial measurement data is used to measure body rates used to reduce spacecraft motion to allow the star trackers to acquire star patterns which requires low body rates on the satellite. Excess heat generated by electronic systems and the cryocooler of the infrared detector is radiated into space by external radiator panels installed on the equipment module on external panels not hosting solar panels. KOMPSAT-3A is part of the Korean Multipurpose Satellite Program developed and operated by the Korea Aerospace Research Institute KARI to establish an operational Earth observation capability that includes satellites carrying optical, infrared and radar payloads to deliver data needed for a variety of purposes. It will continue to provide sub-meter imagery to domestic and international users for the applications of public safety, resource management, environmental monitoring, location-based services, intelligence and disaster monitoring. Additionally to its predecessor Kompsat-3, it carries also a infra-red instrument. Arirang-2, also known as KOMPSAT-2 (Korean Multi-purpose Satellite 2), is a South Korean multipurpose reconnaissance satellite.It was launched from Plesetsk Cosmodrome, Russia at 4:05 PM KST on 28 July 2006. Satellite Imaging Corporation is an official Value Added Reseller (VAR) of imaging and geospatial data products for: We offer satellite imagery and data from the most technologically advanced satellite sensors. Illustration of the KOMPSAT-3A spacecraft (image credit: KARI) Spacecraft: The spacecraft is being … KOMPSAT-3A is equipped with two imaging payloads – the Advanced Earth Imaging Sensor System A (AEISS-A) and an Infrared Imaging Payload. It began to transmit signals at 11 PM the same day. Maximum image dimensions (Across track x along track, km), Level 1R (Corrected for radiometric and sensor distortions), Level 1G (Geometric distortion correction by using SRTM DEM), 80 cm diameter of primary light weight mirror aperture, Line array of 24,000 pixels.

The infrared detector is cooled to 80K by using a pulse-tube cold finger to reduce dark currents. KOMPSAT 3A (Korean Multi-purpose Satellite 3A) is a lightweight Earth observation satellite developed by the Korea Aerospace Research Institute KARI. KOMPSAT-3 can provide sub-meter images with various imaging modes. Kompsat-3A will be a sister spacecraft to the previously launched Kompsat-3 (Arirang-3), both of which were developed by the Korea Aerospace Research Institute (KARI). It is delivering the highest resolution data among the cameras installed on domestic satellites and is capable of acquiring images with maximum spatial resolution of 50-70 cm. It is similar to the KOMPSAT 3 spacecraft. Stars in that field of view are compared to a catalog of known star constellations from which the three-axis orientation of the satellite can be determined to provide very precise pointing information. Overall, the infrared imaging payload acquires imagery at a ground resolution of 5.5 meters. The satellite has a mass of just under 1,000 Kilograms measuring 2.0 meters in diameter and standing 3.5 meters tall. KOMPSAT-3 (Arirang-3) satellite was launched on the H-IIA system on May 17, 2012 from Tanegashima Space Center in Japan. In addition to AEISS also used on KOMPSAT-3, the 3A satellite hosts an infrared imaging system delivered by AIM. These temperature-sensitive IR sensors (IRS) can assist in monitoring of wildfires, volcanic and seismic activities as well as water currents and natural disasters. The KompSat-3 spacecraft consists of a payload-an AEISS (Advanced Earth Imaging Sensor System) camera and a satellite platform that takes it into space. KOMPSAT 3A (Korean Multi-purpose Satellite 3A) is a lightweight Earth observation satellite developed by the Korea Aerospace Research Institute KARI.

The main purpose of the optical KOMPSAT spacecraft is to deliver high-resolution imagery for Geographical Information Systems as well as environmental, agricultural and oceanographic monitoring. Das Programm begann 1994, um die Fernerkundungstechnik in Korea zu entwickeln. The first KOMPSAT mission was launched in 1999 featuring a 470-Kilogram satellite that carried an optical imager with a ground resolution of 6.6 meters. 2 stacks of 12 k pixels each, TDI (Time Delay Integration), < 64 TDI in 4 stages, Source data rate = 16 x 15 Mpixel/s (or 3.84 Gbit/s), Line array of 6,000 pixels, provision of 8 stacks, TDI capability. Notwithstanding KOMPSAT 3’s capacity to deliver panchromatic optical images at a nominal ground sampling distance (GSD) of 70 cm, the next satellite was enhanced with thermal infrared sensor, therefore KOMPSAT-3A became a unique example of space technologies commercialization. KOMPSAT-3A will provide panchromatic resolution of 0.55m and multispectral resolution of 2.20m and also has an infrared sensor at 5.5m resolution. KOMPSAT-2, weighing in at 800kg using a newly developed satellite bus, launched in July 2006 and delivered imagery at a 4-meter ground resolution covering four spectral bands and employing off-nadir imaging techniques.
