Linking Saudi Arabia Loran-C Chain to Mediterranean Chain.

Publication Date	1987

Page Count	9
Abstract	The National Institute for Standards (NIS) is maintaining the Egyptian National Standards. International comparisons of NIS Frequency standard are continuously carried out. To obtain the required traceability, the most widely used system for time dissemination has been the navigational system of the U.S. Coast Guard Loran-C. The only chain that was available for timing in Cairo, Egypt was the Mediterranean (7990). The NIS receives the Loran-C signals from Sellia Marina (7990-M) and Kargabarun (7990-Y). The data are stored and compared with the data received from BIH at Paris and USNO at Washington, DC. By 1985, however, two chains covering Saudi Arabia, came into operation. Since both Loran-C chains can be received at NIS, which is nicely situated between them, it was obvious that NIS can contribute to link them together. Kargabarun, Turkey (7990-Y) of the Mediterranean chain is at 1244 km from NIS and Ash Shaykh Homayd, (8990x) of the North Saudi Arabia at 408 km. This paper presents the results obtained from the two Loran-C chains and comparisons with reports from BIH and USNO. If the necessary arrangements are made, continuous comparisons can be done and information sent to all interested organizations.
