解釋
無動力的通訊衛星-
More attention is paid to using satellite passive microwave remote sensing data in estimating precipitation and many algorithms for the retrieval of rainfall have been developed
衛星被動微波遙感資料在降水估計中的應用日益受到重視，多年來已經發展了多種演算法反演地面降水強度。 -
Finally, the technique of vibration suppression is discussed. the passive isolation that is simple is adopted for high frequency part and the effort of high frequency suppression is obvious. the bandwidth adaptive that doesn ’ t need new plants is adopted for low frequency part and simulation results indicate that the scheme is valid for the suppression of bit error rate increasing produced by satellite platform vibration
最後對振動的抑制方法進行了研究，對高頻振動採用被動隔離方式，該方法操作簡單，對高頻振動抑制效果顯著;對低頻振動採用了自適應帶寬抑制方式，該方法無需添加新器件，對抑制低頻振動帶來的誤碼率增加作用明顯，並進行了模擬驗證。 -
The theory and method of the region passive pseudolites positioning based on geostationary satellite positioning system are systematically discussed
本文系統地討論了基於雙星的偽衛星無源區域定位系統的定位理論以及方法。 -
