Abstract:	Precise point positioning (PPP) provides a precise navigation solution with world-wide coverage using a single GNSS receiver. Single-frequency (SF) PPP has gained more interest in the recent years because of the low-cost of SF-GNSS receivers and their wide applications in the mass market. Real-time SF-PPP is now possible with the availability of both commercial and free real-time precise augmentation corrections. The two major sources of freely available real-time corrections are International GNSS Service real-time service (IGS-RTS) and GNSS augmentation systems such as the satellite-based augmentation system (SBAS). Profound Positioning Inc. (PPI) has developed a real-time SF-PPP technology known as “Instant PPP”. This paper demonstrates the capability of the instant PPP technology to work with the freely available real-time PPP corrections through static and kinematic analysis. The instant PPP was tested with corrections from two different IGS-RTS streams and two SBAS systems. The static test utilized six IGS stations located in North America, Europe and Asia. Furthermore, a kinematic road test is carried out in a suburban area with several overpass bridges. The results from both static and kinematic tests showed that instant PPP with precise corrections can achieve half-meter level horizontal accuracy and one-meter accuracy in the vertical direction in static and suburban scenarios.
