Abstract. The determination of parameters of the Earth's ellipsoid is quite a difficult task that gives no rest to scientists to this day. One of the more famous works is the Struve Geodetic Arc, which was stretched from the Black Sea to the Arctic Ocean by employing the method of a triangulation network and which is included in the UNESCO World Heritage Site list. However, until this project was implemented, many steps of scientific and technological advancement had to be taken, the entirety of which created the conditions for the realization of this project. A study of the method of triangulation measurements, the development of geodetic devices, the state politics of the Russian Empire in the 17th–19th centuries in the field of geodesy, and the development of triangulation during this period are presented in the article. Moreover, a study of the origins of the Struve Geodetic Arc project that led to such a grand result is conducted. The obtained results reveal that certain factors predetermined the favourable conditions for the successful execution of the project of this geodetic arc.

Struve大地弧：三角剖分的发展，技术可能性以及项目的启动

摘要。确定地球椭球体的参数是一项艰巨的任务，至今仍未给科学家带来任何休息。最著名的作品之一是“斯特鲁夫大地弧”，它通过三角网的方法从黑海延伸到北冰洋，被联合国教科文组织列为世界遗产。但是，在实施该项目之前，必须采取许多科学和技术进步的步骤，这些步骤的整体性为实现该项目创造了条件。本文介绍了三角测量方法的研究，大地测量设备的发展，大地测量学领域的17-19世纪俄罗斯帝国的国家政治以及此期间三角测量的发展。此外，对导致如此巨大结果的Struve大地弧项目的起源进行了研究。所获得的结果表明，某些因素为成功执行该大地弧项目预先确定了有利条件。
