Which countries have the highest accuracy hybrid solution?

Our Hybrid Kalman Filtered Terrestrial Multi-Stations and Precise Point Positioning (PPP) algorithm is applied in countries where we have sourced reliable terrestrial CORS data.

These countries are USA, Germany, Spain, France, Austria, Italy, Netherland, Czechia, Belgium, Poland, Portugal, UK and Ireland (partially), Switzerland, Australia, Japan and New Zealand. You will achieve 2-3 cm XYZ absolute accuracy in these countries.

Absolute Accuracy. Differences in X,Y and Z of the MakeItAccurate hybrid post-processing solution compared to results using a local base station. The GNSS data was collected in California, USA, on a KlauPPK full constellation receiver installed on a DJI Matrice210 UAV.
Precision. RMS of observations shown above.
