Because of adopting fixed groundwork, position of every observation station is immovability, agility of instrument is poor, singular fixed stand can not meet the need of modern equipment
由於採用固定地基的方式,各觀測點的位置不動,儀器設備的機動性差,單一的固定站點已不能滿足現代化的裝備要求。In contrast with the measurement of backscattered ultraviolet solar radiation onboard satellites, ir radiance measurements in 9. 6m spectral channel at various instruments onboard meteorological / environmental satellites allow ozone estimates during both day and night. in this paper, we use ir radiance measurements within 9. 6 im spectral channels from moderate resolution spectral radiometer ( modis ) and advanced tiros operational vertical sounder ( atovs ) to retrieve total column ozone based on the operational retrieval system of national satellite meteorological center. for validating retrieval results, both ground based observation and total ozone mapping spectrometers ( toms ) ozone measurements are used and atovs retrieval results are corrected after the validation
本文利用美國noaa衛星上的先進的大氣垂直探測器業務系統( atovs )儀器和地球觀測系統衛星( eos )上的中解析度成像光譜儀( modis )上的9 . 6 m臭氧探測通道的輻射測值,在國家衛星氣象中心業務反演軟體系統基礎上,反演出了兩種儀器探測的大氣臭氧總量,並且利用中國五個常規臭氧觀測站的資料和美國研製的臭氧總量測繪光譜儀( toms )反演的臭氧資料對兩種反演結果進行驗證分析,對atovs反演結果進行了訂正。In this dissertation, we studied the tcra1101plus total station position system, which introduced the principle and characters of the instrument ' s closed loop tracking system. also we explained the cause of prism ' s position error and brought forward mathematic model to correct, moreover, the good results has been drawn form the expenriments. the kinetic survey system have been realized, which the sampling rate attain more than 5hz and the position precision can be less than 2mm on condition that targeted - point moving slowly at the velocity below 2cm / s. having finished the survey system to examine whether the fine - tuning stewart platform in good status, we have finished mensurating the position reference of the fine - tuning stewart platform and the offset of the prism
在此基礎上研製了多臺儀器在線控制高頻采樣動態跟蹤測量系統,采樣率大於5hz ,在跟蹤小於2cm / s低速運動目標時,測量精度好於2mm ;完成對饋源二次精調系統的檢測,包括對二次精調平臺位置基準的標定和觀測棱鏡偏心差的測定;設計不同動態測量實驗,對全站儀動態跟蹤的誤差來源和特點進行了分析;從實驗角度,對全站儀的測量時滯及其穩定性進行了測試分析,給出了定量的結果;比較了全站儀和計算機的內部時間系統,發現兩者存在較大差異。To overcome this problem, not only the meteorological observation network has to be equipped with automated, higher precision, and more economical devices and instruments, but also a synthetic mobile observation system is required for filling in the data gaps between the surface and upper air sounding stations
為了克服這一問題,除了研製自動化程度高、測量精度高和性能價格比高的儀器設備來裝備現有的定點大氣觀測網外,還應建設一些流動的大氣監測系統,以獲得常規大氣觀測臺站空檔間(如大洋、山區和荒漠等無人區)的天氣現象和大氣環境變化的信息。The paper has made detailed observation by the existing apparatus and the field observation stations. based on the image and the vector database of the yutian oasis, the study has obtained the precise coordinates of investigation points by gps technique, and overlapped them with the images. after classifying the images with the maximum likelihood supervised classification method, we import the result into cis software, and analyze the yutian oasis changes about land cover " s quantity, quality and spatial position from 1976 to 2001
本文利用現有儀器設備和野外觀測網站進行詳細觀測,在建立於田綠洲圖像庫和矢量數據庫的基礎上,運用gps技術取得野外考察樣點的精確坐標並與研究區各時期影像疊加,對影像進行了最大似然法監督分類,並將分類結果轉入gis軟體處理,全面分析了1976年至2001年該綠洲的土地覆蓋類型數量、質量與空間上的變化。Since the geomagnetic observation developing for the simplest, the highest degree of automation and digitalization, and the geomagnetic data requiring more integrality and continuity, the developing trend of geomagnetic instrument is the fully digitalization and automation
目前,地磁觀測趨向于簡單化、自動化和數字化,地磁資料也要求完整性和連續性,因此地磁儀器的發展趨勢就是實現自動化及數字化,地磁臺站實現無人職守。This can be achieved once gps timing synchronization is ready
各觀測站之間的儀器需先互相校準,以求精確比較時間數據。分享友人
