Near Real-Time GPS PPP Time Transfer for Business Continuity in Singapore

Driven by the smart nation initiatives, the role of precise time source becomes more significant in highly demanded seamless and efficient municipal services in Singapore. One of the critical requirements is the time continuity which promotes us to build up a Business Continuity (BC) site for continuous time services. Global Positioning System (GPS) based Precise Point Positioning (PPP) technique is one of solutions for precise time transfer from our main laboratory to the BC site for the local realization of Coordinated Universal Time (UTC). In this paper, some preliminary results and observations will be discussed.
