Abstract

Fremgangsmåte for å firme data for bruk av en mottaker i et satellittposisjonssystem eller GNSS, irmbefattende utledning av dataene fjernt fra mottakeren i en server (200), ved å bruke meteorologisk informasjon og en regional eller global, fredimensjonal avbildning av gitterpunkter fra hvilket det beregnes froposfæriske forsinkelser ved hjelp av sfrålefølging gjermom det refraktive feltet utledet fra atmosfæriske målinger av tykk, temperatur og varmdatairmhold, slik som målinger som er tilgjengehge fra meteorologiske myndigheter. Når brukt for å forbedre posisjon bestemt av en brukermottaker som inkluderer en ikke-meteorologisk, klimabasert modell (130) ved å gi zenith-forsinkelser og irmretning (130') for å avbilde dem på bestemte inklinasjoner, serveren inkluderer også en kopi av en slik ikke-meteorologisk modell (230) og gir sine strålefiilgte forsinkelsesverdier som zenith-forsinkelse. Settet med zenith-forsinkelsesverdier for tilsvarende gitterpunkter er sammenlignet i serveren (260) og modifikasjoner blfr utviklet (foretrukket i fraksjonsform) med hvilket den ikke-meteorologiske forsinkelsesverdien krever å bh korrigert for å være nøyaktig. Korreksjonssettet blir redusert ved bilde- kompresjonsteknikker (270) og sendt via satellittene (llOi etc.) i GNSS på lav datarate til brukermottakeren, hvor mottakeren enkelt anvender korreksjonene på zenith-forsinkelser utledet fra sin egen modell. Dersom en brukerposisjon er kjent, kan serveren utlede nøyaktige, froposfæriske forsinkelsesverdier direkte for mottakerposisjonen direkte for sending.
