This paper gives the results of an investigation into the use of different sampling rates and models for the interpolation of perspective‐centre coordinates in GPS‐assisted aerial triangulation. Industry‐standard models and rigorous signal reconstruction filtering have been implemented for two largescale photogrammetric blocks. GPS sampling rate was found to have the most impact on bundle adjustment results in terms of the perspective‐centre residuals. However, the accuracy of object‐space point coordinates was found to be invariant to both GPS sampling rate and interpolation method
