• To support geodetic and cadastral surveying.

http://www.rtknet.gov.my/


MyRTKNet Configuration:

● Network of 50 dual frequency GPS reference stations in Peninsular Malaysia

● Network of 28 dual frequency GPS reference stations in East Malaysia

● Control Centre at JUPEM Headquarter, Kuala Lumpur.


GNSS CORS: ISKANDARnet

• Setup by UTM-GNSS & Geodynamics Research Group.

• Comprises of 4 stations; UTM JB, Port of Tanjung Pelepas , Kolej KomunitiPasir Gudang & Majlis PerbandaranKulai.

• Currently provide GPS observation data & positioning related services.

• A research platform and to support positioning activities.

A Proposed System Design...Radio Occultation (RO) observation & global distribution of RO events.


SISPELSAT (SATELLITE SAILING SYSTEM)

● Owned and operated by Marine Department ofPeninsular Malaysia.

● The primary navigational-aid for vessels navigatingwithin the shore of Peninsular Malaysia

● Design based on International Association ofLighthouse Authorities (IALA) guidelines for thePerformance & monitoring of a DGNSS Service in theband 283.5 – 325 kHz.

● Guarantees service performance of providing(positioning) accuracy of better than 5m at 95%reliability level.


Next…Collaboration

• Inter-Agencies collaboration • Inter-Universities collaboration

(University consortia). • Regional collaborations through

relevant professional organisations.

Partnership cluster

To allow for:• Exchange of data.• Exchange of knowhow.• Collaboration in national and

international cross discipline projects.

• Sharing of cost/facilities.


Collaboration

EUROPEE-GVAP: EUMETNET (European meteorological network) GPS water Vapour Programme; a regional collaboration between 12 European countries, UK and IGS ACs on GPS data sharing for met.
