1、本科畢業(yè)設(shè)計(jì)RTKGPS板卡驅(qū)動(dòng)電路設(shè)計(jì)與開發(fā)摘要自從GPS問世以來,就以其高精度,全天候,全球覆蓋,方便靈活和優(yōu)質(zhì)價(jià)廉吸引了全世界許多用戶。目前,國(guó)內(nèi)GPS應(yīng)用發(fā)展勢(shì)頭迅猛,短短幾年間,GPS在我國(guó)的應(yīng)用已經(jīng)從少數(shù)科研單位和軍用部門迅速擴(kuò)展到各個(gè)民用領(lǐng)域,GPS的廣泛應(yīng)用改變了人們的工作方式,提高了工作效率,帶來了巨大的經(jīng)濟(jì)效益,具有廣闊的應(yīng)用前景。TrimbleBD970GNSS接收模塊作為在GNSS領(lǐng)域的Trimble公司最新技術(shù),應(yīng)用于裝備原始設(shè)備制造商和系統(tǒng)集成,是一款緊湊型的多星座模塊,專為滿足各種精確到厘米級(jí)的定位精度應(yīng)用需求而設(shè)計(jì)。本文闡述了能夠測(cè)試TrimbleBD970
2、GNSS接收模塊的功能的驅(qū)動(dòng)電路板的設(shè)計(jì)原理。此驅(qū)動(dòng)電路板主要由電源模塊,串口通信模塊和LED提示模塊組成。通過此驅(qū)動(dòng)電路板,能夠?qū)崿F(xiàn)上位機(jī)與TrimbleBD970GNSS接收模塊的通信,對(duì)TrimbleBD970GNSS接收模塊的定位輸出、差分輸入、LED指示等功能進(jìn)行方便測(cè)試。關(guān)鍵詞:GPSGNSS驅(qū)動(dòng)電路功能測(cè)試TheDriverCircuitDesignOfTrimbleBD970GNSSReceiverModuleYangLijian(CollegeofScience,SouthChinaAgriculturalUniversity,Guangzhou510642,China)
