data correlator

As a radio astronomical observation technology with very high space resolution, Very Long Baseline Interferometry ( VLBI) has been widely used in the high accuracy deep space probe tracking activities. The correlator is the key data-preprocessing device.

甚长基线干涉测量（VLBI）是重要的射电天文技术，具有极高的空间分辨率，是国际上广泛采用的深空探测器高精度测量手段，相关处理机则是VLBI数据预处理的核心设备。
