About this app

We provide SSR2OSR, our software utility for converting SSRZ stream data into observation-space RTCM MSM correction data for Pseudo Reference Station (PRS / VRS) applications.

SSR2OSR app consumes SSRZ and ephemeris data streams from standard NTRIP casters, connected by mobile Internet, takes your approximate position from smartphone/tablet, and generates RTCM MSM correction data output. This will enable your GNSS RTK rover to use SSRZ broadcast data.
