| Abstract: | The simulation method was employed for studying the impact of the antenna pitch angle and semi major axis on mirror reflection points.The spatial and temporal resolutions of GNSS-R ocean remote sensing satellite constellation which was composed of four and six satellites have been figured out.Constellation formed by 6 satellites has good coverage performance for global 5°×5° ocean grid on the eight hours time. |
