Field: Measurement (Instruments)
Classification: CPC G | IPC G

Claim 0:
1. A method for recreating unavailable measurements in a global navigation satellite system (GNSS) receiver, the method comprising:
receiving at least one tracking signal from a GNSS satellite in a first frequency band, the first frequency band including a target carrier frequency (fk);
receiving at least one correction signal providing at least one of an available pseudorange measurement (Pi) or an available carrier phase measurement (ϕi) at another carrier frequency (fi), wherein the another carrier frequency (fi) is outside of the first frequency band; and
without using any prior measurements from the GNSS satellite at the target carrier frequency (fk), performing at least one of:
deriving, from at least the available pseudorange measurement (Pi), a pseudorange estimate ({circumflex over (P)}k) at the target carrier frequency (fk); or
deriving, from at least the available pseudorange measurement (Pi) and from at least the available carrier phase measurement (ϕi), a carrier phase estimate ({circumflex over (ϕ)}k) at said target carrier frequency (fk).
