An assessment of the precise products on static Precise Point Positioning using Multi-Constellation GNSS [PDF]
Precise point positioning (PPP) is highly dependent on the precise ephemerides and satellite clock products that are used. Different ephemeris and clock products are available from a variety of different organizations.

Multi-Frequency Precise Point Positioning using GPS and Galileo data with smoothed ionospheric corrections [PDF]
The poor signal visibility and continuity associated with urban environments together with the slow convergence/reconvergence time of Precise Point Positioning (PPP), usually makes PPP unsuitable for land navigation in cities.
