Claim 14:
15. The method according to claim 1, wherein the available pseudorange measurement (Pi) is a first pseudorange measurement (Pi), the pseudorange estimate ({circumflex over (P)}k) is a first pseudorange estimate (Pi), the available carrier phase measurement (ϕi) is a first available carrier phase measurement (ϕi), the carrier phase estimate ({circumflex over (ϕ)}k) is a first carrier phase estimate (ϕk), and the another carrier frequency (fi) is a first another carrier frequency (fi), and further comprising at least one of:
without using any prior measurements from the GNSS satellite at the target carrier frequency (fk), deriving, from at least a second available pseudorange measurement (Pi), a second pseudorange estimate ({circumflex over (P)}k) at said target carrier frequency (fk); or
without using any prior measurements from the GNSS satellite at the target carrier frequency (fk), deriving, from at least said second available pseudorange measurement (Pi) and from at least a second available carrier phase measurement (ϕi), a second carrier phase estimate ({circumflex over (ϕ)}k) at said target carrier frequency (fk);
wherein said second available pseudorange measurement (Pi) and said second available carrier phase measurement (ϕi) are measurements at a second another carrier frequency (fi), the second another carrier frequency (fi) being different from said target carrier frequency (fk) and different from the first another carrier frequency (fi).
