One of the fundamental tasks of geodesy is to unifing the height systems of countries worldwide or within a specific region. This will help ensure accuracy in research for transnational and intercontinental projects, such as sea level rise or transnational construction projects. However, traditional methods such as spirit leveling are not feasible due to their high time and cost. One of the recent research directions is the application of relativistic geodesy to unifing the global height system. In this study, the authors developed a simulation to standardize the Asian height system using a network of high-precision optical clocks. The simulation results show that it is possible to unifing the Asian height system with an accuracy of 2 ÷ 3cm. This is a promising result for further practical research.
