摘　　要：在海上环境的影响下,测量船测量的数据存在一定的随机误差。通过介绍外测测量数据包含的数值项,即系统误差、随机误差、趋势项值和周期项值等,重点介绍了数据处理时对测量值中趋势项、周期项等数据的分离,进而得出随机误差项。然后介绍了利用最小二乘拟合残差法分离拟合多向式的可行性,并提出了该方法在数据处理中应用的可行性。Under the influence of marine environment, there are some random errors in the measurement data. Through the introduction of tracking measurement data, including numerical, system error, random error and the trend value and cycle value, this paper introduced separation in the measured value trend and periodic item data in the data processing, and then draws a random error term. Then, this paper introduces the feasibility of using the least squares fitting residual method to separate and fitting the multi direction, and puts forward the feasibility of the application of the method in data processing.
