Subseasonal GNSS Positioning Errors

Linear rate & annual GPS position errors are well studied flicker phase noise (time-correlated) dominates velocity errors crustal pressure load models explain only part of annual signals many other effects contribute to annual signals GPS draconitic errors are pervasive
