A device may use Precise Point Positioning (PPP) correction information to generate Real Time Kinematic (RTK) correction information that can be sent to other devices for RTK-based positioning. In particular, according to some embodiments, the first device having access to PPP correction information may obtain the PPP correction information and generate RTK correction information by determining a virtual RTK base station location and generating, based on the PPP correction information, a virtual Multi-Constellation Multi-Frequency (MCMF) measurement corresponding to the determined virtual RTK base station location. This virtual MCMF measurement (and/or data derived therefrom) can then be sent to other devices as RTK correction information.
