This study focuses on the establishment of a unified height system for Africa called AFRUHS (African Unified Height System) by utilizing atomic 8 clocks and clock networks. The International Association of Geodesy (IAG) has 9 long aims to construct an International Height Reference Frame (IHRF), but the lack of accurate and globally harmonized vertical coordinates, particularly in Africa, has posed a challenge. To overcome this, the researchers propose using clock networks to determine geopotential or elevation differences between distant stations by measuring the gravitational redshift (GR) through clock frequency comparisons. The research employs simulation studies using the ACES (Atomic Clock …
