commercial service (GPS, Galileo) (CS)
Commercial Service(CS) is the name of the Galileo service with the highest position resolution. It is a paid service with a horizontal resolution of less than 1m. It is received with a dual- frequency receiver.
Galileo supports this service with various value-added services which, among other things, provide higher local accuracy. Procedurally, differential correction signals are used, comparable to Differential Global Positioning System( DGPS), which are transmitted by local transmitters. Other value-added services include high data ratedata transmission and time-related services.
In addition to the Commercial Service, other Galileo services include the Open Service, the Safety-of-Life( SoL) Service, the Public Regulated Service( PRS) and the Search and Rescue( SAR) Service.
