From: Investigating GNSS PPP–RTK with external ionospheric constraints
Parameter | Formulation |
|---|---|
\(\overline{B}_{{r \ne p,{\text{DCB}}}}^{{}}\) | \(B_{{r,{\text{DCB}}}} - B_{{p,{\text{DCB}}}}\) |
\(\overline{b}_{r \ne p,i > 2}^{{}}\) | \((b_{r,i} - B_{{r,{\text{IF}}}} + \lambda_{i} N_{r,i}^{q} ) - (b_{p,i} - B_{{p,{\text{IF}}}} + \lambda_{i} N_{p,i}^{q} )\) |
\(\overline{I}_{r,i}^{s}\) | \(I_{r}^{s} + B_{{r,{\text{GF}}}} - B_{{{\text{GF}}}}^{S}\) |
