  3. Introduction • In Malaysia, navigation technology has become an essential tool in various applications for positioning in military and civilian sectors. • With the full operational constellation and modernization of the GNSS such as GPS and GLONASS, the accuracy of positioning has definitely improved.

  4. The Signal Integrity • GNSS signals are weak and easily be interrupted. • Affected by variety types of errors at various stages • Such as: - satellite clock and orbit errors; - ionospheric and tropospheric delays; - receiver clock error; - possible cycle slips; - multipath; - and etc. • Several incidents indicated signals in failure mode and resulted significant position errors.

  6. Aims & Objectives • The National Space Agency (ANGKASA) in collaboration with universities, government and industries sectors is currently in the midst of developing an integrity monitoring system for space-based positioning in Malaysia. • The aim of this project is to provide an integrity monitoring system for space-based navigation and positioning in Malaysia. This aim embarks three objectives: • To establish GPS/GNSS CORS network over Peninsular Malaysia • To determine on integrity and reliability of GNSS and DGPS signals over country • To provide a warning of any signal anomalies at all time. Geospatial World Forum 13-16 May 2013, Beurs-World Trade Centre Rotterdam

  7. Scope of Work • Set-up GNSS ground stations with real-time data streaming. • Set-up control centre at ANGKASA & processing centre at UTM. • Set-up database for GNSS & DGPS integrity monitoring system. • Set-up web-based service for GNSS & DGPS integrity monitoring system.
