【摘要】：隨著科技的發(fā)展，GPS手持機(jī)生產(chǎn)工藝的提高和成本的降低，，越來越多的新型手持機(jī)不斷涌現(xiàn)，并且精度不斷提高。由于其體積小巧、攜帶方便、具有全天候、全方位、實(shí)時(shí)三維導(dǎo)航與定位能力，且具有高靈敏度、高精度、自動(dòng)化、價(jià)廉、使用方便等優(yōu)點(diǎn)，所以手持機(jī)在測繪行業(yè)已經(jīng)有越來越多的應(yīng)用。 CORS技術(shù)的應(yīng)用和發(fā)展日益成熟，使得常規(guī)RTK作業(yè)的精度和距離有了較大的提高，由于網(wǎng)絡(luò)技術(shù)，計(jì)算機(jī)網(wǎng)絡(luò)管理、無線電通信技術(shù)等因素的進(jìn)步，使得手持RTK接收機(jī)測量技術(shù)更加可行。 論文概述了GNSS、CORS、影響GPS測量精度的因素和手持機(jī)，重點(diǎn)介紹了手持RTK測量技術(shù)；手持RTK精度的對比分析；手持RTK相對于常規(guī)RTK精度的比較分析；手持RTK在數(shù)字測圖中的應(yīng)用分析。 由于手持RTK接收機(jī)測量技術(shù)與其他測量技術(shù)相比，具有更多的優(yōu)點(diǎn)。在數(shù)字測圖方面，它可以滿足大部分的測圖要求，所以，手持RTK接收機(jī)測量技術(shù)應(yīng)用于數(shù)字測圖已經(jīng)是一個(gè)發(fā)展趨勢，它的應(yīng)用對于測繪行業(yè)來說其效益是顯而易見的。
[Abstract]:With the development of science and technology, more and more new handsets are emerging and the precision is improving. Because of its small volume, convenient carrying, all-weather, omni-directional, real-time three-dimensional navigation and positioning ability, it has the advantages of high sensitivity, high precision, automation, cheap, easy to use, etc. The application and development of CORS technology is becoming more and more mature, which makes the accuracy and distance of conventional RTK work greatly improved. As a result of network technology, computer network management, With the development of radio communication technology and other factors, the measurement technology of handheld RTK receiver is more feasible. This paper summarizes the factors of GNSS,CORS, affecting the accuracy of GPS measurement and handheld machine, especially introduces the hand-held RTK measurement technology, the comparison and analysis of hand-held RTK accuracy, the comparison and analysis of hand-held RTK relative to conventional RTK accuracy, and the application of hand-held RTK in digital mapping. Compared with other measurement techniques, handheld RTK receiver measurement technology has more advantages. In the aspect of digital mapping, it can meet most of the mapping requirements. Therefore, the application of hand-held RTK receiver measurement technology in digital mapping has been a development trend, and its benefits are obvious to the surveying and mapping industry.
