Fast precise point positioning (Fast‐PPP) provides Global Navigation Satellite System corrections in real time. Satellite orbits and clock corrections are shown to be accurate to a few centimeters and a few tenths of a nanosecond which, together with the determination of the fractional part of the ambiguities, enable global high‐accuracy positioning with undifferenced Integer Ambiguity Resolution. The new global ionospheric model is shown to provide corrections accurate at the level of one total electron content unit over well‐sounded areas and differential code biases at the level of tenths of a nanosecond. These corrections are assessed with permanent receivers, treated as rovers, located at 100 to 800 km from the reference stations of the ionospheric model. Fast‐PPP achieves decimeter level of accuracy after a few minutes, several times faster than single‐ and dual‐frequency ionospheric‐free solutions, using a month of Global Positioning System data close to the last Solar Maximum and including equatorial rovers.
