恒星坐标系的建立及其潜在的应用前景研究

Establishment of stellar coordinate systems and its potential applications

摘要

本文提出了一种模拟赤道坐标系建立的新的坐标系即“恒星坐标系”。它们均为确定天体在天球上位置的关键工具，赤道坐标系以地球自转轴的无限延伸线作为主轴，这一主轴会受到地球自转轴的进动和章动的影响。而恒星坐标系则基于遥远的北极星与地球中心的连线作为主轴，具有相对较高的稳定性，有效避免了因地球自转和公转所引起的不稳定漂移，且不受岁差和章动的影响。恒星坐标系在多个领域可能会发挥重要作用：包括但不限于天文学研究、航天测控与导航、深空探测、卫星通信与地球观测、导航与定位技术、时间系统校准，以及军事应用等等。这些领域的广泛应用进一步证明了恒星坐标系在科学研究和实际应用中的重要价值。

Abstract

This paper proposes a new coordinate system based simulates the equatorial coordinate system. They are all key tools to determine the position of celestial bodies on the celestial sphere. The equatorial coordinate system takes the infinite extension line of the earth’s rotation axis as the main axis, which is affected by the precession and rotation of the earth’s rotation axis. The stellar coordinate system is based on the connection between the distant North star and the center of the earth as the main axis, has a relatively high stability, effectively avoids the unstable drift caused by the earth’s rotation and revolution, and is not affected by the age difference and rotation.
