Product Information

On May 1, 2013, the GF-1 spacecraft yawed 90° and performed side-slither calibrations three times on orbit. This maneuver produced a radiometric flat-field input to the sensor so that the relative response of each detector was determined for the same exposure level ( Figure 16). The side-slither derived detector correction parameters were then used to improve the quality of the GF-1 imagery. A significant improvement in image correction was achieved (Ref. 14). Since the inception of the Gaofen project in 2013, China had an increasingly clear view of the planet. Launched in April 2013, Gaofen-1 (gao fen = high resolution) can cover the globe in just four days. On 26 April 2013 the first satellite of CHEOS was successfully launched by LM-2D, which marked that CHEOS had entered into a new stage with features "contructing, operating, applying". This launching has also carried 3 microsatellites which is made by Ecuador, Argentina, Turkey. Gaofen-1 is based on the CAST small satellite bus designed and developed by the China SpaceSat Co. Ltd. of Beijing (also referred to as DFH Satellite Co. Ltd.), the commercial subsidiary of CAST (Chinese Academy of Space Technology). F-1 employs the CAST-2000 bus, it is configured with two 2 m Pan/8 m MS camera and a four 16 m MS medium-resolution and wide-field camera set. GF-1 realizes an integration of imaging capacity at medium and high spatial resolution and with a wide swath, the design life is 5 years with a goal of 8 years.

The balloons would also allow surveillance for longer periods of time than the few minutes it takes a satellite in LEO to pass overhead. SuperView-1 constellation includes 2 satellites and provides imagery with 0.5 meter panchromatic resolution and 2 meter multispectral resolution. The swath width is 12 km and the descending node time is 10:30 am. It possesses high agility and runs with multiple collection modes including long strip, multiple strips collect, multiple point targets collect and stereo imaging. The maximum single scene can be 60 km * 70 km. While the rules for using chaos and cheos are generally straightforward, there are some exceptions to keep in mind. 1. Specific TerminologyWhile details have been published of the Gaofen 1 through 7 satellites, those designed Gaofen-8 remain classified, indicating military customers. No details were published about the satellite's capabilities. State media reported that the satellite will be "mainly used for land surveys, city planning, land rights confirmation, road network design, crop yield estimation and disaster prevention and mitigation."

In addition, GF-2 features some onboard intelligent health monitoring and self-management capabilities, including autonomous battery charging control, a battery discharge depth safety guard, payload subsystems start/stop control etc., which provide a better control for the batteries, momentum wheel, control moment gyros, solar array drive mechanism and data transmission antennas- in particular a better balance between the work strength and stress environment, avoiding early failure problem occurrences, and ensuring the longevity goals to meet the design requirements. Under the strategic guidelines for the Medium and Long Term National Science and Technology Development Program(2006-2020), CHEOS was established as one of the sixteen major national science and technology projects. It is approved to build up a high-resolution earth observation system based on satellites, stratospheric airships and aircrafts, and improve relevant ground systems to carry out application demonstration. By combining other relevant observation systems, they will provide all-weather, all-time, and global earth observation capability. By 2020, it has established a new generation of advanced earth observation system that carries out the observation of land, atmosphere and ocean, thereby providing information service and strategic decision making to various fields, such as modern agriculture, disaster prevention and reduction, resource and environment monitoring, and so on.

Gaofen-1 is based on the CAST small satellite bus designed and developed by the China SpaceSat Co. Ltd. of Beijing (also referred to as DFH Satellite Co. Ltd.), the commercial subsidiary of CAST (Chinese Academy of Space Technology). The satellite is equipped with a pair of solar panel wings, each with three solar panels. The CAST-2000 bus is a small platform with high performance, expandability and flexibility. The CAST-2000 bus is of HJ (Huan Jing)-1A and -1B mission heritage, both spacecraft were launched in Sept. 2008.Psychosocial, sociocultural and behavioral determinants of health; Substance Use; person-centered care in addiction; injectable opioid agonist treatment; Harm reduction June 2014: The GF-1 spacecraft (a demonstration satellite in the GF family) and its payload are operating nominally. The agile GF-1 provides several acquisition modes. For example, the spacecraft can provide up to 4 different roll acquisitions in one orbit and/or provide a 90º side-slither calibration (Ref. 7).

When it comes to choosing between chaos and cheos, context is an important factor to consider. The meaning and implications of these two terms can vary depending on the situation in which they are used. Examples Of Different Contexts Cheos is characterized by a sense of harmony and balance, where seemingly random and chaotic events come together to form a cohesive whole. It is often associated with creativity and innovation, as it allows for new and unexpected ideas to emerge from the chaos.

Many other approaches, such as the integrated installation of star sensors and camera, a high stable temperature control environment, and the introduction of a special microvibration seismic isolation system, ensured the satellite camera optical axis pointing stability to ≤ 2 arcsec with respect to the attitude measurement reference frame. The high-precision satellite orbit determination, attitude determination and thehigh stability control design ensures the satellite imagery location accuracy reaching the 20~39 m level in the absence of ground control points, which is better than the design specifications.

Conclusion

The satellite is configured with two barrel-mounted panchromatic and two MS (Multispectral) cameras, providing a combined swath width of 45.3 km. The revisit frequency of the spacecraft is in the range of 4 -69 days, depending on the particular application, and the observation range of the mission covers a region between 80ºN to ~80ºS.

Multi-spectral sensing systems such as the Landsat Thematic Mapper remote imager and weather satellites produce images with a few relatively broad wavelength bands. The imager may capture a visual spectrum image and also one in infrared, but still they are limited in their ability to perceive information that may otherwise be present in a different part of the spectrum.

Origin of chaos

The main goal of the HDEOS series is to provide NRT (Near-Real-Time) observations for disaster prevention and relief, climate change monitoring, geographical mapping, environment and resource surveying, as well as for precision agriculture support. The major users of the observation data will be the Ministry of Land and Resources, Ministry of Environmental Protection, and the Ministry of Agriculture.
