Latest Patents

Yiquin Chen holds a patent titled "Adaptive estimation of GNSS satellite biases." This invention introduces a first pair of a wide-lane (WL), zero-difference (ZD) bias filter and a corresponding supplemental WL bias predictive filter. These components work together to determine the time-variant wide-lane bias for a received satellite based on adaptive estimation responsive to tuned dynamic noise. Additionally, a second pair of narrow-lane (NL), zero-difference (ZD) bias filter and corresponding NL bias filter/code-phase bias filter is utilized to determine the time-variant NL bias for a satellite. The correction signal generated includes the WL ambiguities, the time-variant WL bias, the NL ambiguities, and the time-variant NL bias, along with code bias or code-phase bias for each received satellite within a corresponding GNSS constellation.
