InstrumentEstimateHelmertTransformation
This program estimates a 3D Helmert transformation between two networks (frame realizations, e.g. GNSS satellite or station network). Each separate data represents a satellite/station/… (e.g. 32 GPS satellites). The instrument data (x,y,z position) considered can be set with startData. The Helmert parameters are set up according to parametrizationTemporal for each timeIntervals and are estimated using a robust least squares adjustment.
