Witryna2 - Narrow-lane: The second step uses the ionosphere-free combinations for phase and pseudo-range. Once the wide-lane ambiguity is known, there is one remaining ambiguity to solve for, associated to an equivalent wavelength of 10.7 cm on the iono-free phase combination (Narrow-lane ambiguity). This ambiguity fixing is performed … masking policy californiaWitrynaLikewise, we have to frequently estimate narrow-lane UPDs in our PPP-RTK model. 2.2User(solution(For the user solution, we use the UPD estimates above to correct the float wide-lane and narrow-lane BSD ambiguity estimates at a single station. Then we use sequential bias fixing (Dong and Bock, 1989) for the wide-lane ambiguity hyatt hotels isle of palms sc
