導讀：PIS 2022第八屆精準農(nóng)業(yè)與信息化高峰論壇“大咖”駕到！

　　【農(nóng)機網(wǎng) 會展預告】PIS 2022第八屆精準農(nóng)業(yè)與信息化高峰論壇“大咖”駕到！
 

　　主題探究
 
　　金雙根院士長期從事衛(wèi)星導航、大地測量、衛(wèi)星遙感和空間行星探測及應用，取得了多項原創(chuàng)性成果。
 
　　? 衛(wèi)星導航(Satellite navigation)是指采用導航衛(wèi)星對地面、海洋、空中和空間用戶進行導航定位的技術。常見的GPS導航，北斗星導航等均為衛(wèi)星導航。
 
　　? 大地測量是為建立和維持測繪基準與測繪系統(tǒng)而進行的確定位置、地球形狀、重力場及其隨時間和空間變化的測繪活動。大地測量確定地面點位、地球形狀大小和地球重力場的精密測量。內(nèi)容包括三角測量、精密導線測量、水準測量、天文測量、衛(wèi)星大地測量、重力測量和大地測量計算等。大地測量學屬于空間地理信息科學，是對物體的信息的描述，具體體現(xiàn)在3W(what何物、where何地、when何時)上，廣義上講大地測量學就是描述物體空間信息的科學。
 
　　? 衛(wèi)星遙感，是指從地面到空間各種對地球、天體觀測的綜合性技術系統(tǒng)的總稱。可從遙感技術平臺獲取衛(wèi)星數(shù)據(jù)、由遙感儀器以及信息接受、處理與分析。遙感技術是正在飛速發(fā)展的高新技術，它已經(jīng)形成的信息網(wǎng)絡，正時時刻刻、源源不斷地向人們提供大量的科學數(shù)據(jù)和動態(tài)信息。
 
　　? 行星探測是人類長期借助于天文望遠鏡觀測行星圓面的細節(jié)，發(fā)現(xiàn)了土星環(huán)、木星衛(wèi)星和天王星；運用萬有引力定律陸續(xù)發(fā)現(xiàn)了海王星和冥王星；借助于近代照相術、分光術和光度測量技術對行星表面的物理特性和化學組成有了一定的認識。
