摘　　要：在采用VE464进行可控震源施工时,会出现箱体记录的导航数据丢失情况,需要对这些缺失数据进行复测。文章针对VE464箱体记录的导航数据丢失情况,为了减少野外测量补点数量,通过对震源导航原始数据进行统计和分析,对硬件的缺陷进行验证,找出丢失数据的原因。针对原因制定出可行的解决方法,来减少因为箱体本身缺陷丢失导航数据,减少野外可控震源的测量补点数量。When the VE464decoder is used for seismic construction,the navigation raw data recorded by VE464 is lost,and surveying group needs to collect the missing data in the field.In view of these data loss recorded in the VE464,in order to reduce re-surveying these missing points in the field.This paper verifies the defects of hardware by statistics and analysis of vibroseis navigation original data,and finds out the reasons for the loss of data.For these reasons,a feasible solution is developed to reduce the number of re-surveying points in the field.
