  【農(nóng)機(jī)網(wǎng) 會(huì)展預(yù)告】PIS 2022第八屆精準(zhǔn)農(nóng)業(yè)與信息化高峰論壇“大咖”駕到!
 

  主題探究
 
  金雙根院士長(zhǎng)期從事衛(wèi)星導(dǎo)航、大地測(cè)量、衛(wèi)星遙感和空間行星探測(cè)及應(yīng)用,取得了多項(xiàng)原創(chuàng)性成果。
 
  ? 衛(wèi)星導(dǎo)航(Satellite navigation)是指采用導(dǎo)航衛(wèi)星對(duì)地面、海洋、空中和空間用戶(hù)進(jìn)行導(dǎo)航定位的技術(shù)。常見(jiàn)的GPS導(dǎo)航,北斗星導(dǎo)航等均為衛(wèi)星導(dǎo)航。
 
  ? 大地測(cè)量是為建立和維持測(cè)繪基準(zhǔn)與測(cè)繪系統(tǒng)而進(jìn)行的確定位置、地球形狀、重力場(chǎng)及其隨時(shí)間和空間變化的測(cè)繪活動(dòng)。大地測(cè)量確定地面點(diǎn)位、地球形狀大小和地球重力場(chǎng)的精密測(cè)量。內(nèi)容包括三角測(cè)量、精密導(dǎo)線測(cè)量、水準(zhǔn)測(cè)量、天文測(cè)量、衛(wèi)星大地測(cè)量、重力測(cè)量和大地測(cè)量計(jì)算等。大地測(cè)量學(xué)屬于空間地理信息科學(xué),是對(duì)物體的信息的描述,具體體現(xiàn)在3W(what何物、where何地、when何時(shí))上,廣義上講大地測(cè)量學(xué)就是描述物體空間信息的科學(xué)。
 
  ? 衛(wèi)星遙感,是指從地面到空間各種對(duì)地球、天體觀測(cè)的綜合性技術(shù)系統(tǒng)的總稱(chēng)??蓮倪b感技術(shù)平臺(tái)獲取衛(wèi)星數(shù)據(jù)、由遙感儀器以及信息接受、處理與分析。遙感技術(shù)是正在飛速發(fā)展的高新技術(shù),它已經(jīng)形成的信息網(wǎng)絡(luò),正時(shí)時(shí)刻刻、源源不斷地向人們提供大量的科學(xué)數(shù)據(jù)和動(dòng)態(tài)信息。
 
  ? 行星探測(cè)是人類(lèi)長(zhǎng)期借助于天文望遠(yuǎn)鏡觀測(cè)行星圓面的細(xì)節(jié),發(fā)現(xiàn)了土星環(huán)、木星衛(wèi)星和天王星;運(yùn)用萬(wàn)有引力定律陸續(xù)發(fā)現(xiàn)了海王星和冥王星;借助于近代照相術(shù)、分光術(shù)和光度測(cè)量技術(shù)對(duì)行星表面的物理特性和化學(xué)組成有了一定的認(rèn)識(shí)。
