Abstract (en)
[origin: WO2022173528A2] A first pair of a wide-lane (WL), zero-difference (ZD) bias filter and corresponding supplemental WL bias predictive filter determines the time -variant wide-lane bias for a corresponding received satellite based on adaptive estimation responsive to tuned dynamic noise (S820). A second pair of narrow-lane (NL), zero-difference (ZD) bias filter and corresponding NL bias filter/code -phase bias filter determines the time-variant NL bias for a corresponding satellite based on adaptive estimation on adaptive estimation responsive to tuned dynamic noise (S822). A correction signal comprises the WL ambiguities, the time-variant WL bias and the NL ambiguities and the time -variant NL bias, for each received satellite within a corresponding GNSS constellation (S824).
