Claim 18:
19. A system for determining a location using a global navigation satellite system (GNSS), the system comprising:
first receiving means configured to receive at least one tracking signal from a GNSS satellite in a first frequency band, the first frequency band including a target carrier frequency (fk);
second receiving means configured to receive at least one correction signal providing at least one of an available pseudorange measurement (Pi) or an available carrier phase measurement (ϕi) at a second carrier frequency (fi), wherein the second carrier frequency (fi) is outside of the first frequency band; and
processing means configured to:
(a) without using any prior measurements from the GNSS satellite at the target carrier frequency (fk), derive, from said available pseudorange measurement (Pi), a pseudorange estimate ({circumflex over (P)}k) at the target carrier frequency (fk);
(b) without using any prior measurements from the GNSS satellite at the target carrier frequency (fk), derive, from said available pseudorange measurement (Pi) and said available carrier phase measurement (ϕi), a carrier phase estimate ({circumflex over (ϕ)}k) at said target carrier frequency (fk); or
(c) both (a) and (b).
