CHINA'S EARTH OBSERVATION SATELLITE, DUBBED 'GAOFEN-3 03,'

Context

On April 7, 2022, China launched a new Earth monitoring satellite. This satellite will join the country's land-sea radar satellite constellation. It will take photographs to aid China in protecting its maritime interests.

Key Points

  • Gaofen-3 03 is the name given to the spacecraft.
  • It was launched from the Jiuquan Satellite Launch Centre using a Long March-4C rocket.
  • The satellite has been successfully placed in its intended orbit.
  • This freshly launched satellite will be linked to the Gaofen-3 and Gaofen-3 02 satellites currently in orbit.
  • These three satellites will create a land-sea radar satellite constellation, capturing consistent, dependable synthetic aperture radar (SAR) images.

Images from SAR

  • Every day, Earth Observation (EO) satellites record a large number of SAR images. SAR images are capable of processing images during all-weather operations. 
  • The resulting images have a high spatial resolution. 
  • These photos have a 1-meter resolution, which enhances China's monitoring capabilities.

Utilization of the Satellite

  • The satellite's photographs will aid in the mitigation and prevention of maritime disasters, as well as in the monitoring of the dynamic marine environment, environmental protection, marine research, agriculture, water conservation, and meteorology. 
  • It will also aid in the protection of the country's maritime rights and interests.
