Abstract

We show in this note a simple exercise to overcome a common preconception among Geodesy students about the “best” reference ellipsoid. This helps students to overcome their previous ideas based on a purely geometric vision of the reference ellipsoids and advance to a more physical point of view, where the Earth’s gravity plays a fundamental role.

学生对物理测地线的先入之见:“最佳”参考椭球

在这篇笔记中，我们展示了一个简单的练习，以克服大地测量学学生对“最佳”参考椭球体的普遍偏见。这有助于学生克服他们以前基于参考椭球的纯粹几何视觉的想法，并推进到更物理的观点，其中地球引力起着基本的作用。

期刊介绍： The journal publishes original research papers in the field of geodesy and geophysics under headings: aeronomy and space physics, electromagnetic studies, geodesy and gravimetry, geodynamics, geomathematics, rock physics, seismology, solid earth physics, history. Papers dealing with problems of the Carpathian region and its surroundings are preferred. Similarly, papers on topics traditionally covered by Hungarian geodesists and geophysicists (e.g. robust estimations, geoid, EM properties of the Earth’s crust, geomagnetic pulsations and seismological risk) are especially welcome.
