天文射电干涉大地测量原理天文射电干涉大地测量(原文简称ARIES)是美国国家宇航局喷气推进实验室的一项计划项目,该室位于加利福尼亚的帕萨迪纳,由加州理工学院管理。ARIES 原理就是通过利用远在我们星系以外、实际上位于所知宇宙的边缘的河外射电源,高精度地测量地面位置间的距离。这些遥远的类星体和射电星以随机射电信号的形式发射巨大的能量,信号最终以宽阔的波前达到地球。ARIES 系统由一对天线组成,其中一根为固定的,另一根为可
Astronomy Radio Interferometry Geodesy Principles Astronomy Radio Interference Geodesy (ARIES) is a planned project for NASA’s Jet Propulsion Laboratory in Pasadena, California, managed by Caltech. The ARIES principle is to measure the distance between ground locations with high accuracy by utilizing an out-of-river radio source that is actually located at the edge of the known universe beyond our galaxy. These faraway quasars and radio stars emit huge amounts of energy in the form of random radio signals that eventually reach the Earth with a wide wavefront. The ARIES system consists of a pair of antennas, one of which is stationary and the other of which is ok
