Sammendrag Jordas atmosfære står for store og små forstyrrelser av GNSS signaler som skal nå en bruker på jordas overflate. Forstyrrelsene fører til at posisjonsbestemmelse med romgeodetiske teknikker avviker fra den potensielle nøyaktigheten et gitt GNSS tilbyr. Den største feilkilden fra signalets gang gjennom atmosfæren er forårsaket av ionosfæren. Ionosfæren er et dispersivt medium for frekvenser over 30MHz som gjør det mulig for to-frekvente mottakere å estimere eller eliminere signalets forsinkelse gjennom ionosfæren. Tradisjonelt blir den ionosfære forskyldte forsinkelsen også da TEC estimert ved å anvende kode og fasemålinger sammen. Selv om kodemålinger er mindre nøyaktig enn fasemålinger blir de benyttet for å estimere fa...
