i. Owned and Operated by Department of Survey and Mapping Malaysia (JUPEM).
ii. Objectives:
* For GNSS Real-time Positioning.
* Reference Frame and Coordinates System.
* Geodynamic Studies.
iii. Use of a network of reference stations to model the systematic errors and provides the possibility of an error reduction.
i. Network of 50 dual frequency GNSS reference stations in Peninsular Malaysia
ii. Network of 28 dual frequency GNSS reference stations in East Malaysia
iii.Control Centre at JUPEM Headquarter, Kuala Lumpur.

Marine Navigation - SISPELSAT
IALA Recommendation on the Performance andMonitoring of DGNSS Services in the Frequency Band283 - 325 kHz
DGNSS system with coverage of Peninsular Malaysia :Control Station: Port Klang2 Remote Monitoring Station4 Broadcasting (Reference) Station:
By improving accuracy and safety of maritime navigation, the DGNSS system is able to accomplish the following:
�Increased nominal accuracy from 10-15m (GPS only) to 1-3m with DGPS.
�Faster transit times for commercial shipping
�Increased safety through reduced risk of collisions
�Cleaner seas through reduced risk of maritime accidents
�Better position for marine studies – hydrographic survey
�Aids to navigation system – positioning of Buoy
�Oceanographic studies/research
�Oil exploration
�Fisheries
Benefits Of SISPELSAT
ISKANDARnet
� A GPS positioning support system that provides a precise and accurate GPS satellite data correction services.
� Coverage of Iskandar
Development Region (IDR)
� Three CORS stations.

The Way Forward
� Ensure full capitalization of GNSS usage in country
� Participate in International works on GNSS applications and development
� Promote and Optimized GNSS infrastructure usages
� Intensify GNSS related R&D
� Encourage local GNSS industries development
� Encourage locally produced GNSS applications
