1 Introduction MRT48 and BT68 were the geodetic infrastructures used for geodetic, mapping and cadastral survey for Peninsular Malaysia and East Malaysia respectively The introduction of GPS at JUPEM in 1987 lead to the establishment of GPS networks in the Peninsular Malaysia, Sabah and Sarawak. The presence of these passive networks serves its purpose relatively well, especially in mapping and engineering applications. However, nowadays most precise applications of GPS such as for the establishment of zero-order networks, make use of active GPS stations, for eg. MASS With the widespread use of GPS and technological innovations nowadays, real-time GPS applications began to gain even wider group of users 2 Sydney, Australia, April

6 MyRTKnet Data Flow Reference station data streams into the GITN IP cloud via 64K leased lines. From the GITN cloud, all reference station data is immediately sent to Seksyen Geodesi KL over a 1M leased line. Remote users connect by getting onto the internet using GPRS or GSM to ISP and selecting the IP address of the GITN Internet Gateway port The GITN Internet Gatway forwards requests on port 8080 to the GPStream computer on which the NTRIP server is running. Other users can also access the wenserver at for access to customizable Rinex files for post processing and other services. Courtesy of John Serink of Trimble Upon receipt of the NMEA GGA string from the particular user, the system will begin to stream network RTK corrections to the user.

15 CONCLUSION The introduction of MyRTKnet to surveying and mapping communities has opened up new applications and vast possibilities to the world of navigation and positioning in Malaysia. Currently MyRTKnet with 78 stations and spacings of between 30 to 120 km is providing real-time corrections with a latency of less than one second using Virtual Reference Station (VRS) technique. Under the 10th Malaysia Plan ( ), an additional of another 70 stations is proposed with emphasis on the public delivery system CONTRIBUTION TO IGS 30 Sydney, Australia, April
