SSRZ Format
SSRZ is a general, highly flexible, open SSR correction format developed by Geo++. SSRZ includes various bandwidth-optimization concepts as well as flexible resolutions and message streams to allow for scalable positioning services or SSR corrections exchange.
The following table lists all SSRZ providers as of April 16, 2025, along with their corresponding organizations and relevant web resources.
The SSRZ format includes a unique “Provider ID” and “Stream ID” to clearly identify each SSRZ data stream. This allows users to effectively differentiate between multiple SSRZ streams. Geo++ centrally manages the SSRZ Provider ID, following a structure similar to the SSR Provider ID in RTCM. Updates to the online table occur more frequently than those to the SSRZ Format document.
Organizations operating an SSRZ stream that is not yet listed are encouraged to reach out to us at support@geopp.de for inclusion.
