It is situated at the School of Civil and Structural Engineering of the Nanyang Technological University in Singapore (NTUS). The station was established under an agreement for cooperation between NTUS and the 'Delft Institute for Earth Oriented Space Research' (DEOS) at 'Delft University of Technology' (DUT) in the Netherlands. This agreement was conceived under the umbrella of the 'GEODYnamics of South and South-East Asia' (GEODYSSEA) project, sponsored by the European Union (EU), in which both institutes took part together with many other institutes in several European and Asian countries. We have decided to use the NTUS acronym as the 4-character ID of the station. For the time being, DEOS will act as the operational center for this new station, expanding its international network which already comprises the KOSG, WSRT, IRKT and MDVO stations. However, pending the outcome of ongoing discussions, the 'Bundesambt fuer Kartografie und Geodasie' (BKG) in Germany (formerly IfAG), will probably take over the responsibility for this station later this year, which will allow DEOS to move the receiver to yet another station in Bandung, Indonesia. The antenna of the GPS system at NTUS is mounted on a steel mast of about 1 m high, located on the roof of the building of the School of Civil and Structural Engineering of NTUS. It consists of a strong and rigid 7 storyconcrete construction firmly anchored to and partially embedded in a range of low hills on the west side of the city of Singapore. The geographic location fills a large hole in the coverage of the global IGS network. The GPS system consists of an Allan Osborne TurboRogue SNR-8000 receiver (ser.no. 175) connected to a Dorne Margolin T chokering antenna (ser. no. 177). It is running from its internal clock and at the moment there are no plans to provide an external frequency source. The approximate coordinates of the station are: X = -1508023 m Y = 6195577 m Z = 148799 m and the height of the antenna reference point (bottom of chokering) above the geodetic marker on top of the mast is 77.6 mm. A station log sheet with complete information will be submitted later today. As of August 30, 1997 (DOY 242), the data will be submitted to the European Regional Data Center at BKG (IfAG) in Germany, which will take care of further distribution to the IGS community. Test data which have been collected since June 28, 1997, will be available on request. Requests should be sent to: Boudewijn.Ambrosius@lr.tudelft.nl. Last but not least I would like to thank Prof. Pan Tso-Chien, dr. Tor Yam Khoon and dr. Cheong Hee Kiat from NTUS for all their efforts to enable the establishment of this new station in such a remarkably short time. Less than 3 months elapsed between the initial contact and the beginning of operations. I am sure the station will provide a valuable contribution to the IGS and that it will be of great importance for many kinds of GPS applications in Asia and for Singapore in particular.
