Abstract

Intercomparison of radio signals received simultaneously at several sites from several sources with small mutual angular separation provides a powerful astrometric tool. Applications include tracking the Lunar Rover relative to the Lunar Module, determining the moon's libration, measuring winds in Venus's lower atmosphere, mapping Mars radiometrically, and locating the planetary system in an inertial frame.

摘要

同时从几个源在几个站点接收的具有小相互角分离的无线电信号的相互比较提供了一种强大的天文测量工具。应用包括跟踪月球车相对于登月舱的位置，确定月球的天平动，测量金星低层大气中的风，对火星进行辐射测量制图，以及在惯性参考系中定位行星系统。
