Optical Remote Sensing Satellite

l Ocean Monitoring Satellite Series (HY Series)

DFH has developed a series of ocean satellites,including HY-1 A/B/C/ D. HY-1A is China's first satellite for marine color observation. With Ocean Color and Temperature Scanner, HY-1A can reach 1600km swath. By detecting ocean color elements, e.g., chlorophyll content and suspended sediment, it provides service for developing and utilizing marine biological resources, construction and management of harbors, marine pollution monitoring and prevention, marine zone resources development and marine science study. HY-1B is the follow-up satellite of HY-1A, its observation capability and detection accuracy has been further improved, and the actual in-orbit lifetime is up to 10 years.
HY-1C/D are China's first civilian marine satellite constellation. The satellite constellation effectively improves observation ability for global ocean monitoring, coastal resources and ecology environment, ranking among the best in international ocean color remote sensing area.

l Environment and Disaster Monitoring constellation (HJ Family)

DFH has developed and launched HJ-1 A/B, HJ-2 A/B and HJ-1-C satellites continuously, constructs the first small satellite constellation of environment and disaster monitoring.
HJ-1 A/B are two optical satellites in Environment and Disaster Monitoring and Forecasting Constellation,designed for environmental monitoring, disaster situation reporting, post disaster evolution, and mineral prospect. HJ-2 A/B are the follow-up project of HJ-1 A/B,and the 2 satellites have the same technical status. The payloads include 16-meter camera, hyper-spectral camera, infrared camera and atmospheric correction instrument, with 16m ( multi-spectral), 48m / 96m (hyper-spectral) and 48m /96m (infrared) remote sensing imaging capabilities to Earth and synchronous atmospheric detection capabilities.
HJ-1 A/B were launched in September 2008;HJ-2 A/B were launched in September 2020.

l Venezuela Remote Sensing Satellites (VRSS-1/2)

China and Venezuela have cooperated on two remote sensing satellites. The two satellites are turnkey projects including KHTT, through which the Venezuela space development ability has been greatly improved.
VRSS-1 is DFH’s first exported satellite. It carries two 2.5m PAN/10m MS cameras. The satellite is mainly used for land resource investigation and assessment, dynamic monitoring and management, resource utilization, environment and disaster monitoring, urban construction. It was launched in September 2012.
VRSS-2 is developed by the joint-team of China and Venezuela engineers. It carries a 1m PAN/4m MS camera and an Infra-Red Camera. The satellite's main tasks are land resource investigation and assessment, dynamic monitoring and management, resource utilization, environment and disaster monitoring, agriculture investigation and urban construction. VRSS-2 was launched in October 2017.

l GF-1&6 satellite Family

DFH has developed and launched GF-1、GF-1(02/03/04) and GF-6 satellites, the data from these satellites have become an important source of land resources survey, water conservancy agriculture and urban construction. Their data have become essential sources for such projects as land resources surveys, water conservancy agriculture and urban construction.
GF-1 takes advantage of the platform’s high bearing capability, carrying two HR and four wide-swath cameras. Its resolution is 2m PAN/8m MS with 60km swath and 16m MS with 800km swath. GF-1 satellite was launched in April 2013.
GF-1(02/03/04)consists of three satellites with the same technical status based on GF-1. Each satellite carries two cameras with 2m PAN/8m MS resolution and 66km swath. GF-1(02/03/04) was launched in March 2018.
GF-6 has realized the domestic development of 8-spectrum CMOS detectors, and the "red-edge" band, which can effectively reflect the unique spectral characteristics of crops,contributing to precision agriculture. GF-6 satellite was launched in July 2018.
In October 2020, GF-1(02/03/04)and GF-6 four satellites formed a constellation in orbit, achieving 2m PAN/8m MS global coverage observation capability for 11 days.

l Super View satellite Family

SuperView-1 satellites are the first domestic non-government constellation with high agility and multi-mode imaging. The satellites have a resolution of 0.5m PAN/2m MS. With high agile ability, the satellite provides multiple collection modes including long strip, multiple strips collect, multiple point targets collect and stereo imaging.
The first two satellites were launched in December 2016 and the second two satellites were launched in November 2018. The four-satellite constellation improved the revisit time to 1 day anywhere globally, which marking the milestone of independent commercial operation in China's remote sensing satellites.
