Research on Common Mode Error Extraction Method for Large-Scale GPS Network

  • Based on 138evenl y distributed  IGS coordinate  time  series  spanning more than 10years site -to-site  coefficents  in  lar ge scale GPS network were anal yzed.Their  site -to-site  coefficients  indicate si gnificant  corelationshi p even when the between-site  distance more than 5 000km.Thereforethis paper  proposes  a new method introducing coefficients  as weight  factor  to  calculate  common mode errorand  it  improved  the  correlation-based spatial  filterin g techni que.Time series  from global  and regional  networks were used  to verif y this new method.The results  show that  this  improved coefficientbased spatial  filterin g techni que overcomes  the  spatial  scale  limit  and effectivel y extracts  common mode error  of GPS coordinates  time  series.
