APNH: Asia-Pacific northern hemisphere COMS-1 was constructed by EADS Astrium, and is based on the Eurostar-3000S satellite bus, … It is split into two modules which are electrically independent. CMDPS (COMS Meteorological Data Processing System): With the development of the COMS system, NMSC/KMA (National Meteorology Satellite Center/Korea Meteorological Administration) has been focusing on utilizing the COMS observed data and the foreign satellite data as well. Thrusters 2 x 7 (10 N) are being used for wheel desaturation, and for orbit control. The CMOS FPA having 1432 x 1415 pixels is passively cooled and regulated around 10ºC. Meteorology, Ocean monitoring, experimental communication, Meteo Imager, Ocean colour Imager, S-/L-Band transponder, Ka-band end-users around the globe, oceanography data for the Korean peninsula and experimental COMS is part of a 15-year Small area scans may range in size from a pixel to a full disk; 1.6º x 1.6º is an example of what can be achieved. Then, the radiance of an observed image will be computed by employing the gain parameters. Although driven by conflicting mission requirements, the COMS is the first geostationary 3-axis stabilized satellite for Earth observation, with pointing performances showing large margins. The objectives of COPS call for 3 multibeam functions within the coverage regions of South Korea, North Korea, and the Dongbei region (northeast China). The COMS INR system architecture and the resulting INR ground processing is composed of the following four mains modules, as shown in the Figure 34. 34): 1) It is based on “a posteriori” compensation of the geometric error of the image location or the effects of any perturbations on the image geometry (the ‘image motion compensation’) to be performed on-ground. It is positioned at 128.15˚E and provided real-time meteorological data for most of Asia and Oceania. Standard IR split window channel (cloud, SST, yellow sand detection), TIR2 window 2 • After one full year in orbit in the late summer of 2011, the COMS satellite is behaving beautifully and meets all requirements whether in terms of image quality (radiometrically and geometrically), or in terms of availability, and fuel consumption. 2) The error compensation is mainly performed by a simple linear interpolation, called the ‘linear error correction’, by estimating (short term) and applying the ‘correction angle’ “CorrAngles(t).”. Research Institute, KARI, to design and manufacture the first Korean multi-function Meteo Imager: the Imager is a multi-spectral channel two-axis scanning radiometer, and The adopted approach of pre-processing the GOCI and MI imagery consists in observing perturbations within the images themselves, after acquisition, with respect to contribution models and then correcting those images, by ground processing, utilizing landmarks (from observation within image), attitude measurements (from instrument telemetry or from platform telemetry at a higher rate if needed) and ranging data (orbit data). These hourly variations in coastal water properties can be basic dataset to develop an algorithm for catching the ocean current movement, i.e. It will use an apogee motor to raise itself into geosynchronous orbit. - The CMDPS (COMS-1 Meteorological Data Processing System) provides 16 baseline products including information on Atmospheric motion vector, Asian dust, SST (Sea Surface Temperature) and LST (Land Surface Temperature) over the East Asian region. - The Moon observation and dark space observation are carried out monthly and quarterly, respectively, to check of the variation of the MI radiometric performance. FDS also provides COMS operation related functions such as oscillator updating parameter calculation, sensor interference management, and Earth acquisition parameter calculation after emergency sun reacquisition. In addition, provision of a beam switching function for high-speed multimedia services including the internet via satellite in the public communications network for all coverage regions. - Comments and corrections to this article are always welcome for further updates. COMS-1 is a geostationary weather satellited operated by the Korean Meteorological Agency (KMA) which was launched back in 2010.
