On the study of the high dynamic flight characters of re - entry spacecrafts , positioning method of dynamic correction is brought forward 接著結(jié)合載體高速運(yùn)動的特性,提出了動態(tài)修正的定位方法。
The design of valve cam is mainly to design cam profile curve and is carried out in " dynamics correction method " in this paper 配氣凸輪的設(shè)計(jì)主要就是設(shè)計(jì)凸輪廓形,本文選用“動力學(xué)修正法”進(jìn)行設(shè)計(jì)。
This method is based on the bent ionosphere model and the coefficient of dynamic correction is introduced into traditional cosine correction model to achieve dynamic correction of ionosphere delay . so the position error of over correction can be overcomed 該方法以bent電離層模型為基礎(chǔ),在余弦電離層修正模型的基礎(chǔ)上,引入動態(tài)修正系數(shù),從而克服了采用通常修正方法帶來的過修正誤差。
The results show that the accuracy can be improved above 150 km after using the dynamic correction method and the processed data can meet real - time requests after being filtered . the results and simulation methods can be used for reference in engineering practise 本文提出的動態(tài)修正方法、通過預(yù)測濾波滿足實(shí)時性要求以及仿真過程中采用的仿真方法和手段,在工程實(shí)踐中有一定的實(shí)用價(jià)值和借鑒意義。
While according to dynamics correction method , the valve displacement curve has to be design , which can be acquired by boundary condition and calculation method . then by dynamics analysis , the tappet displacement curve equation can be obtained based on the dynamics differential equation . thus , the design of cam profile can be carried out based on the tappet displacement curve equation 按照動態(tài)設(shè)計(jì)的動力學(xué)修正方法進(jìn)行設(shè)計(jì)時,又得先進(jìn)行氣門升程曲線的設(shè)計(jì),利用一定的邊界條件和計(jì)算方法得到氣門確定的運(yùn)動規(guī)律,再通過動力學(xué)分析,根據(jù)建立的動力學(xué)微分方程,經(jīng)過計(jì)算得到挺柱的升程曲線方程,至此,就可以根據(jù)挺柱的升程曲線進(jìn)行凸輪輪廓曲線的設(shè)計(jì)。
Then , gps error sources and their influences on positioning accuracy are analyzied . moreover , we simulated the gdop changes along the whole trajectory to decide the best poiont for gps receiver to start working . finally , the dynamic correction method and predictive , filter are simulated and validated via advanede simulation and modeling platform 最后采用先進(jìn)仿真平臺對動態(tài)修正定位方法和定位信息實(shí)時性預(yù)測進(jìn)行仿真驗(yàn)證,結(jié)果表明,通過動態(tài)電離層延遲修正,在150km以上高空能有效提高定位精度;采用預(yù)測濾波后,能使得定位結(jié)果達(dá)到實(shí)時性精度的要求。
