gps控制網(wǎng)設(shè)計與質(zhì)量分析_畢業(yè)論文(2)3

1、西南科技大學城市學院本科生畢業(yè)論文IGPS控制網(wǎng)設(shè)計與質(zhì)量分析控制網(wǎng)設(shè)計與質(zhì)量分析摘要：摘要：本文研究的中心內(nèi)容是如何優(yōu)化建立GPS控制網(wǎng)并對影響其質(zhì)量的因素進行分析，本文從GPS控制網(wǎng)原理四類設(shè)計以及四大原則進行設(shè)計討論和研究如何求得既滿足測量結(jié)果的必要精度，又盡可能少地花費人力、物力、財力和時間，也就是在一定支出下，取得最大經(jīng)濟效益的網(wǎng)形和觀測綱要，同時又使數(shù)據(jù)處理工作量最小，解決這樣的布網(wǎng)設(shè)計問題。結(jié)論是，要提高GPS控制網(wǎng)的精度

2、指標：首先，增加觀測期數(shù)，優(yōu)化布網(wǎng)原則，這樣測得的獨立基線數(shù)就會增加，可以提高控制網(wǎng)的可靠性精度。關(guān)鍵詞：關(guān)鍵詞：GPS控制網(wǎng)；優(yōu)化設(shè)計；布網(wǎng)原則；質(zhì)量分析；西南科技大學城市學院本科生畢業(yè)論文IIII目錄前言....................................................................................................................
