摘　　要：全球导航卫星系统(Global Navigation Satellite System,GNSS)的应用日趋广泛,然而各接收机生产商提供的数据记录格式各不相同。国际上普遍采用RINEX(一种与接收机无关的转换格式)格式数据作为数据后处理的标准输入。RINEX格式从其出现至今经过了一系列演化,诞生了不同的版本。在实际应用中涉及不同版本的数据时。尤其是编程读写RINEX文件时,对读写数据格式定义的不恰当可能造成严重的错误。本文集中对RINEX迄今为止广泛应用的几个版本的观测数据文件的标准格式进行说明,并就不同版本RINEX格式观测数据文件的应用进行比较,结合我国正在建设的北斗卫星导航系统(BDS)引出关于数据文件格式方面的一些认识。Global navigation satellite system （GNSS） has been applied more and more widely, however the data re- cord formats provided by different receiver manufacturers are quite different. The Receiver Independent Exchange Format RINEX is internationally used to format the standard import while post-processing data. Ever since it was proposed, RINEX has been optimized and several versions have been developed. Even the identical operation on different RINEX versions of data may look different, in which case the inappropriate definition of data format can lead to fatal errors. This paper introduces several versions of RINEX observation data which are most widely used so far, compares different versions of RINEX files and presents preliminary discussion on data file formats to be used in Chinese BeiDou Navigation Satellite System.
