Fiji’s Geodesy Section of the Ministry of Lands and Mineral Resources, through the Pacific Community (SPC) Pacific Geospatial & Surveying Council (PGSC) Partnership Desk requested Geoscience Australia to compute International Terrestrial Reference Frame (ITRF) coordinates for one hundred and fifty-four (154) geodetic control stations across the Islands in the Fiji Archipelago, Rotuma and its dependencies Archipelago and Ceva-i-ra Island. The following three (3) geodetic survey campaigns GPS/GNSS measurements observed from 10th to 17th November 2019, 8th to 15th December 2019, and 26th January to 2nd February 2020 (Lal et al., 2022). The GPS data was processed using version 5.2 of the Bernese GPS Software in a regional network together with selected International GPS Service (IGS) sites. The GPS solutions were constrained to the ITRF2020 reference frame through adopting IGS20 coordinates on selected IGS reference sites and using the final IGS earth orientation parameters and satellite ephemerides products. These coordinates provide the coordinate reference frame for the project of the modernisation of Fiji’s geodetic datum.
