Abstract

Fremgangsmåter og systemer for bestemmelse av posisjon til seismiske kilder og mottakere er offentliggjort. Signaler som er mottatt av en første antenne behandles for å bestemme dens 3D-koordinatposisjon. Signaler som er mottatt av den første antennen og en andre antenne kombineres og behandles for å estimere en romlig vektor mellom den første og den andre antennen. Den romlige vektoren adderes til 3D-koordinatposisjonen for den første antennen for å tilveiebringe en 3D-koordinatposisjon for den andre antennen. Ved bruk av 3D-koordinat-posisjonen for den andre antennen, kan en 3D-koordinatposisjon for en seismisk kildeenhet eller mottaker beregnes, så vel som en vertikal korreksjon for reflekterte seismiske signaler som er mottatt av mottakeren.
