【摘要】 普通手持式GPS应用于精准农业中时,其定位精度如何;两台GPS同时测定是否能够提高测定精度。文中通过实验结果对这些问题进行了分析。结论是在宽阔、无遮挡、无干扰的地区普通手持式GPS的定位精度可以达到在5米的范围以内;而用两台GPS同时测定时,其定位点的漂移变化并无相关性,从而说明这样测定并不能提高定位精度。更多还原

【Abstract】 By analyzing experimental results, this paper not only researched the accuracy of ordinary hand-held GPS receiver for positioning in precision agriculture, but also discussed the feasibility of improving precision using two hand-held GPS receivers at the same time. It is presented that the positioning accuracy variety range can get to 5 meters when ordinary hand-held GPS receiver is used in a wide, bare region without disturbed. When two ordinary hand-held GPS receivers worked at the same time, there were no pertinency between two series of excursion data of the fixed points. It indicated that the method can’t be used to improve positional accuracy.更多还原
