GNSS transformation: significant differences between Trimble Access and STAR*NET I am currently testing least-squares adjustment software and have encountered issues when combining GNSS coordinates from a Trimble rover with MicroSurvey STAR*NET. During testing, I observe...

Adaptive Stochastic Extended Method Boosts Least‑Squares Solving

An adaptive stochastic extended iterative method based on REK achieves provable R‑linear convergence in expectation for the minimum‑norm least‑squares solution, reported in September 2025. getnews.me/adaptive-stochastic-exte... #leastsquares #stochastic

a plot of 400 values of a measured quantity (dependent variable, vertical axis) vs. measurement index (independent variable, horizontal axis), overlaid with a simple linear regression (ordinary least squares) fit involving 16 sinusoidal frequencies

this is an uncanny fit to 400 measured values using 16 sinusoidal frequencies! this time it's grant work, not contract work, so i will be able to explain this in more detail eventually... for now, it's just a work in progress that looks cool :)
