ABSTRACT
The Sultanate is bordered on the west by Saudi Arabia, United Arab Emirates, Yemen, and on the north, east, and south by the Gulf of Oman and the Arabian Sea. The only known classical geodetic datum in Oman is the Fahud Geodetic Datum of 1954, which was established by the Iraq Petroleum Corporation for the Petroleum Development Oman operation. Beginning in 1964, Hunting Surveys, Ltd., established an extensive control network based on the Fahud Datum of 1954, and this enterprise took over 8 years to develop. The astronomical observations were approximately located on a 25 km grid in order to provide control for relative gravity surveys. Six to ten pairs of circum-meridian observations and 8–13 pairs of time stars were generally observed for the astrofixes.
