Correction to: GPS Solutions (2018) 22:67 https://doi.org/10.1007/s10291-018-0731-0
In the original article, some typos regarding Eq. (3) and Table 9 are introduced. Corrections to Eq. (3)
STEC = N1 l1 + N2� l2� N � l� N1 l1 +H⋅ 2 2 H H � � = P1 ⋅ M1 + P2 ⋅ M2
=H⋅
(3)
= M1 ⋅ 𝜇1 V + M2� ⋅ 𝜇2� V � ( ) = 1 − 𝜇2 M1 V + 𝜇2� M2� V �

V and V ′ are VTECs for the whole ionosphere at IPP1 and IPP2, respectively; 𝜇2 and 𝜇2′ are the shape functions of the voxels for the second-layer corresponding to IPP1 and IPP2; M1 and M2′ are the standard mapping functions at IPP1 and IPP2, equal to l1 ∕H and l2� ∕H respectively. The wrong table references in Section “Assessment” are corrected as below: “It is worth mentioning that the number of available days is less than 365, as shown in Tables 1, 8 and 9 in Appendix B, because the days in which the selected station was used in the GIMs computation are not considered for a fair assessment.” “As shown in Table 9, the BIMF improved dSTEC using JPLG GIMs as well, with an improvement given by %dB in more than 70% of cases.” Publisher’s Note Springer Nature remains neutral with regard to jurisdictional claims in published maps and institutional affiliations.
