Formula for impact analysis in terms of \({\mathbf{\Delta d}}\)

A (PTA-p*p)

 

\(\Delta {\mathbf{e}}^{{\left( {\text{A}} \right)}} = {\mathbf{W}}\left( {{\mathbf{V}}^{\text{T}} - {\mathbf{U}}} \right)^{ - 1} \Delta {\mathbf{d}}\)

B (ITA-p*p)

 

\(\Delta {\mathbf{e}}^{{\left( {\text{B}} \right)}} = {\mathbf{W}}\left( {{\hat{\mathbf{q}}\mathbf{V}}^{ - 1} {\hat{\mathbf{g}}} - {\mathbf{U}}} \right)^{ - 1} \Delta {\mathbf{d}}\)

C (ISA-i*i)

\(\Delta {\mathbf{w}}^{{\left( {\text{C}} \right)}} = {\mathbf{W}}\left( {{\mathbf{V}}^{\text{T}} - {\mathbf{U}}} \right)^{ - 1} {\hat{\mathbf{g}}\mathbf{V}}^{{ - {\text{T}}}} \Delta {\mathbf{h}}\)

\(\Delta {\mathbf{w}}^{{\left( {\text{C}} \right)}} = {\mathbf{W}}\left( {{\mathbf{V}}^{\text{T}} - {\mathbf{U}}} \right)^{ - 1} \Delta {\mathbf{d}}\)

D (PSA-i*i)

\(\Delta {\mathbf{w}}^{{\left( {\text{D}} \right)}} = {\mathbf{W}}\left( {{\hat{\mathbf{q}}\mathbf{V}}^{ - 1} {\hat{\mathbf{g}}} - {\mathbf{U}}} \right)^{ - 1} {\mathbf{V}}{\hat{\mathbf{q}}}^{ - 1} \Delta {\mathbf{h}}\)

\(\Delta {\mathbf{w}}^{{\left( {\text{D}} \right)}} = {\mathbf{W}}\left( {{\hat{\mathbf{q}}\mathbf{V}}^{ - 1} {\hat{\mathbf{g}}} - {\mathbf{U}}} \right)^{ - 1} \Delta {\mathbf{d}}\)
