SAPOS data can contain information from a networking calculation or can be generated in a networking calculation. With SAPOS data provided via different transmission media and techniques, GNSS-based position determinations can be performed in different defined service areas (SAPOS services) much more accurately than with the use of the uncorrected GNSS.
