    a. Background

    As part of Singapore's cadastral survey modernisation initiatives, the coordinated cadastre was established and SVY21 was gazetted as the spatial reference system for Singapore.

    SiReNT is a new infrastructure replacing SIMRSN, i.e. Singapore Integrated Multiple Reference Station Network. The primary objectives of having SiReNT and SIMRSN are similar: to define Singapore's official spatial reference framework and to support the gazetted cadastral system in SVY21.




    b. System Overview

    SiReNT comprises five GPS reference stations connected to a Data Control Centre (DCC) at Government Data Centre (GDC). The entire set-up is made up of advanced GPS equipment and sophisticated computer hardware, software, communications and network.

    SiReNT supports a great variety of applications. It provides data reliability, efficiency and productivity of survey work for land surveyors with the aid of GPS technology. It also offers a wide range of GPS data services with various accuracy levels ranging from metres to centimetres to suit different applications.




    c. Reference Stations

    SiReNT has 5 GPS Reference Stations. These GPS Reference Stations receive satellite signals 24 hours a day and transmit GPS data continuously to the Data Control Centre (DCC) for storage and processing. The five reference stations are strategically located at extreme corners of Singapore Island - Senoko, Nanyang Technological University (NTU), Keppel, Nanyang Polytechnic and Loyang, so as to provide an island-wide coverage.




    d. Services

    SiReNT offers 3 types of service, namely Post Processing (PP) On-Demand, Post Processing (PP) Archive, Real Time Kinematic (RTK) and low accuracy Differential Global Positioning System (DGPS) to suit different applications.




    e. Applications

    SiReNT offers a channel for various GPS applications in the market to further enhance positional accuracies and network coverage. It can support an infinite list of applications.

    You can use SiReNT for:
    • cadastral surveying
    • engineering surveying
