基于移动基准站的舰船系统试验数据处理方法研究

针对舰船系统试验基准数据处理利用GNSS定位数据通过固定基准站差分解算后再获得相对关系解算的不足,分析该方法面临的难题及难以满足远距离大航区试验的现实问题,提出基于载波相位实时动态差分处理的移动基准站解算方法。在研究GNSS差分定位原理基础上,结合经典载波相位双差方法,通过单历元实时差分,建立无固定基准站的相对数据解算模型。基于采集的实测数据,分析基线解算精度,验证所提出方法在舰船系统试验基准数据处理中的可行性和质量效果。

A data processing method in warship system test based on moving base station

Aiming at the insufficiency of benchmark data processing in warship system test based on fixed base station differential calculation through GNSS positioning data,this paper analyses the difficulty that conventional method is facing with,which can not fit the test of long-range and great navigation area.It proposes the data processing method of carrier phase differential calculation based on moving base station. Based on these analyses of GNSS differential calculation principle,combined with classic carrier phase double-difference,it builds a differential calculation model based on moving base station through real-time single epoch processing.Using the data collected in real-time situation,it gets the baseline calculating precision, and validates the feasibility and result quality in warship system test benchmark data processing.
