Zusammenfassung:	Method for detecting motion of an object using GNSS signals, including (i) measuring distances between a GNSS antenna and GNSS satellites with carrier phases at a first time; (ii) computing distances between known positions of antenna and satellites at first time; (iii) for each satellite, calculating first set of residuals=distances in (i)- distances in (ii); (iv) measuring distances between antenna and satellites with carrier phases at a second time; (v) computing distances between known positions of antenna and satellites at second time; (vi) for each satellite, calculating second set of residuals=distances in (iv)- distances in (v); (vii) differencing first and second sets of residuals; (viii) computing a metric based on set of differences in (vii); (ix) comparing metric to a threshold; (x) based on comparison in (ix), determining if object moved or possibly moved between first time and second time.
