Web29 jul. 2024 · The ionosphere-weighted model takes advantage of constraining of the DD slant ionospheric delays (DD-SID) to the a priori values, which is done here by the introduction of the pseudo-observations with assigned variance factors. A similar approach is applied for zenith tropospheric delays as well as for station coordinates. Webcombinations. However, spread in the ionosphere-free position solution using L1/L5 linear combination of observations is more than that of L5 single-frequency observation. Hence, to reduce noise in linear combination of observations, we have investigated the benefits of using common Doppler estimate two-frequency signal tracking.
