The mission of Letové prevádzkové služby Slovenskej republiky štátny podnik (LPS SR), a state enterprise, is the provision of air navigation services in airspace and on assigned aerodromes of the Slovak Republic. Every passenger on scheduled or charter flight over the territory of the Slovak Republic is an indirect client of LPS SR.
