About

SabahPOS realises the Sabah Geocentric Datum 2020 (SGD2020) (ITRF2014 @ epoch 2020.9467, GRS80) from the SLSD/JTU CORS network using double-difference GNSS processing. Results are delivered in SGD2020, the legacy cadastral BRSO grid (Timbalai 1948 / RSO Borneo, EPSG:29873), and orthometric height from the MyGeoid model — the coordinate systems Sabah surveys use today, on a modern GNSS foundation.
