摘要
随着航天技术的飞速发展以及新型号航天发射任务对测控系统提出的新要求,采用新技术新方法提高航天测量船的岸船对时精度非常必要。重点介绍卫星双向时间比对技术的基本原理,分析岸船卫星双向时间比对中影响岸船对时精度的主要误差源及其精度,提出实现高精度岸船对时需注意的问题。
Along with the high speed development of spaceflight technology and the new demand of new spaceflight launch task put forward to TT&C system,it is necessary to adopt new technology and new method to improve the ship-land time synchronization precision.This paper emphatically introduces the base principle of two-way satellitte time synchronization technology,analyzes the primary error and its precision which affects the ship-land time synchronization precision in the ship-land two-way satellitte time synchronization,and puts forward some attentive problems in the high precision ship-land time synchronization realization.
