摘要: 随着科学技术的发展,测量工具和测量手段也发生了变化,其中测量型GNSS呈现价格降低、体积缩小的趋势。目前市场上一整套商用GNSS测量系统的价格从几万到几十万不等,且由于地面基站和移动站体积大、携带不方便等原因,使得商用GNSS测量系统的使用人群仅限于部分专业测量人员,难以在大众市场普及。当今众多领域如无人机、机器制导、精密农业等对高精度定位需求的增加,又促使GNSS测量系统向低成本、高精度、小型化、轻型化发展。本文对U-BLOX的NEO-M8P低成本OEM型GNSS接收机进行50 km基线下的静态观测,基于RTKLIB的测试结果和精度分析表明,低成本GNSS测量系统能够达到厘米级定位精度,能够满足测量工作和GIS应用的需求。试验证明,使用此低成本测量系统能降低测量任务的经济成本,是测量级GNSS接收机中经济适用的选择。

Abstract: With the development of science and technology, measuring tools and measuring methods have also changed, the measurement type GNSS showed a trend of price to reduce and the shrinkage of the whole. On the market at present commercial prices ranging from tens to hundreds of thousands of GNSS measuring system, and ground base station and mobile station due to large size, unconvenient to carry, making commercial GNSS measurement system using the crowd is limited to some measurement professionals, in the mass market popularity in many fields. Because of the increase in demand for high precision positioning, such as unmanned aerial vehicle (uav), machine guidance, precision agriculture today, prompted GNSS to low-cost and high-precision measurement system miniaturization Light-duty development. In this paper, the U-type BLOX NEO-M8P low-cost OEM GNSS receiver, the static under 50 km baseline observation, based on RTKLIB accuracy of test results and analysis showed that low-cost GNSS measurement system can achieve cm-level positioning accuracy, meet the needs of measurement and GIS application tests. It showed that using the low-cost measurement system can reduce the economic cost of measurement tasks, which is a measuring levels of GNSS receiver economical choice.
