Visit to Nanyang Technological University

26 September - 9 October 1999, Singapore

This will be one of the many visits by some of the staff and graduate students from the SNAP group on the Singaporean Multi-Base Station GPS Network and Applications project (click here for more information) at Nanyang Technological University (NTU). This visit involved working with Khoo Hock Soon and Chen Xiaoming on aspects of the data model used to store GPS data collected from the four stations situated around the island. Initial development had been carried out at the University of New South Wales using a Leica CRS1000 logging data into an Oracle 8 database. NTU will be using Leica SR9500's logging data into Microsoft SQL Server. The visit also involved testing the transmission of GPS data from the Yishun base station into the server located at NTU.

Server installation at Surveying & Mapping Lab, Nanyang Technological University. Two 64K ISDN leased lines have already been installed connected to the server via a router. Database development will be carried out on both Microsoft SQL Server and Oracle 8/8i relational databases.
