KOMPSAT-3A is the world’s first civilian satellite that is equipped with a high-resolution, infrared(MWIR) sensor which enables nighttime observation. It also provides the optical images with high resolution of 50 cm or less for the second in the world following the US.
The technology of improving the optical image quality by 30% or more without degradation using diagonal data to provide 38-cm-class images was developed for the second following the EU.
The high-resolution electro-optical spaceborne camera AEISS-A(Advanced Earth Imaging Sensor System-A) developed by KARI and accommodated on KOMPSAT-3A platform features 50cm class optical photography, which marks the highest resolution among cameras mounted on domestic satellites. The IR sensor, which is capable of detecting heat on the ground, is used to observe fire, volcanic activity and urban thermal islands during nighttime, even under any weather conditions.

CBERS is a cooperative program between CAST (Chinese Academy of Space Technology) of the People's Republic of China, and INPE (Instituto de Pesquisas Espaciais) of Brazil (government agreement of both countries for the development and operation of two satellites). The program was signed in July 1988 to establish a complete remote sensing system (space and ground segment) to supply both countries with multispectral remotely sensed imagery.
In Nov. 2002, the governments of China and Brazil decided to expand the initial agreement by including another two satellites of the same kind, CBERS-3 and 4, as the second generation of the Sino-Brazilian cooperation effort. The planned cooperative CBERS-3&4 program of CAST and INPE employs enhanced versions of spacecraft and instruments. The specification of the project was agreed upon and closed in July 2004.

SPOT-7 is a high-resolution wide-swath imaging spacecraft built and operated by Airbus Defence and Space taking over the majority of Spot Image after the government support of the SPOT program was terminated. SPOT-6 – launched in 2012 – and SPOT-7 are identical spacecraft, based on the AstroSat-250 satellite bus and use the NAOMI (New AstroSat Optical Modular Instrument) payload to acquire optical imagery to ensure the continuity of SPOT data, building on experience gained through previous missions, particularly SPOT-5 that launched in 2002.
The SPOT-7 spacecraft is built for a ten-year mission featuring two NAOMI cameras to cover a 60-Kilometer ground swath, 120km using single-pass mosaic imaging. Overall, the satellite can achieve a resolution of two meters in panchromatic and eight meters in multispectral mode covering the visible and near-infrared spectral bands.

From a 620-km ascending sun-sync orbit, it has a 12/24-km swath (depending on the imaging mode), stereo-par capability and ±45º off-nadir tilting capacity. Its multispectral camera has a panchromatic and 4 spectral bands (R,G,B,NIR), at 10 bits. This allows Deimos-2 to provide 75-cm pan-sharpened imagery.
Deimos-2 was designed to provide a cost-effective and highly responsive service to cope with the increasing need of fast access to sub-metric imagery. As evidence of this, it provides near-real time image tasking, downloading, processing and delivery to the end user. It has a collection capacity of more than 150,000 km2/day with a two-day average revisit time worldwide. The...

The overall objective is to provide data continuity to be used for cartography, regional observation, disaster monitoring, and environmental monitoring.
The post-ALOS program of JAXA has the goal to continue the ALOS (nicknamed Daichi) data utilization - consisting of ALOS-2 (SAR satellite) and ALOS-3 (optical satellite) in accordance with Japan's new space program.
The state-of-the-art L-band Synthetic Aperture Radar (SAR) aboard ALOS-2, which is an active microwave radar using the 1.2 GHz frequency range, which, in responding to society's needs, has enhanced performance. The SAR is capable of observing day and night, and in all weather conditions.
ALOS-2 has a spotlight mode (1 to 3 m) and a high resolution mode (3 to 10 m). It allows comprehensive...
read moreSentinel-1 is a two satellite constellation with the prime objectives of land and ocean monitoring. The goal of the mission is to provide C-Band Synthetic Aperture Radar (SAR) data continuity following the retirement of ERS-2 and the end of the Envisat mission.
To accomplish this the satellites carry a C-SAR sensor, which offers medium and high resolution imaging in all weather conditiions. The C-SAR is capable of obtaining night imagery and detecting small movement on the ground, which makes it useful for land and sea monitoring.
Sentinel-1 will work in a pre-programmed operation mode to avoid conflicts and to produce a consistent long-term data archive built for applications based on long time series.
The mission benefits numerous services. For example, services that relate to the monitoring of Arctic sea-ice extent, routine sea-ice mapping, surveillance of the marine environment, including oil-spill monitoring and ship detection for maritime security,...
The FY-3 series of CMA/NSMC (China Meteorological Administration/National Satellite Meteorological Center) represents the second generation of Chinese polar-orbiting meteorological satellites (follow-on of FY-1 series). The FY-3 series represents a cooperative program between CMA and CNSA (China National Space Administration); it was initially approved in 1998 and entered full-scale development in 1999. Key aspects of the FY-3 satellite series include collecting atmospheric data for intermediate- and long-term weather forecasting and global climate research.
The FY-3 series satellites monitor large-scale meteorological disasters, weather-induced secondary natural hazards and environment changes, and provides geophysical parameters for scientific research in climate change and its variability, climate diagnosis, and predictions. The FY-3 series renders global and regional meteorological information for aviation, ocean navigation, agriculture, forestry, marine activities,...
KOMPSAT-5 is an earth observation satellite equipped with Korea's first all-weather SAR.
The SAR mounted on KOMPSAT-5 emits microwaves to an object on the ground and synthesizes the reflected signal to produce an image. It enables ground observation even during nighttime and poor weather conditions.
As the SAR image can supplement the optical camera, which can record only the visible light spectrum, it is utilized in mutual supplementary operations with the high-resolution optical images of KOMPSAT-3 and KOMPSAT-3A.
KOMPSAT-5 observes the Korean Peninsula four times a day. The transmitted image data are used for public safety, natural disaster forecasts, land/resource management and environmental monitoring.
The primary mission of the KOMPSAT-5 system is to provide high resolution mode SAR images of 1 meter resolution, standard mode SAR images of 3 meter resolution and wide swath mode SAR images of 20 meter resolution with viewing conditions...
