Overview

The paper demonstrates a method to reconstruct the Earth's gravitational field using satellite gradiometry, indicating advanced measurement techniques for precise data analysis.

Key Points

  • This research aims to explore the principles of measuring the Earth's global gravitational field using satellite technology.
  • Utilized a high-precision three-axis gravity gradiometer on a low Earth orbit spacecraft.
  • Employed a GNSS receiver for accurate orbit measurements necessary for EGF analysis.
  • Developed a numerical integration program for spacecraft orbit considering various forces.
  • Compiled a matrix of equations related to Stokes coefficients for EGF reconstruction.
  • Used the least squares method to correct EGF model harmonics based on model measurements.
  • Successfully reconstructed the Earth's gravitational field harmonics from the EGF model.
  • Achieved agreement in amplitude differences between the reconstructed and EGM2008 models.
  • Selected an optimal spacecraft orbit for efficient gradiometric measurements.
  • Estimated accuracy characteristics for key instruments on the spacecraft.
