  Introduction
  The pseudorange-based differential global positioning system
  
  DGPS technique is extensively used for ground control point
  
  GCP establishment of medium and high resolution satellite imagery
  because this technique can provide accurate positioning results
  at the 1 m level, provided the correction data age is less than
  10 s, and the user is within 50 km of the reference station
  Parkinson
  and Enge 1996. Rizos and Satirapod
  2001 stated that the
  DGPS technique generally provides an accuracy of ter than 3
  m in the horizontal component at twice the distance root mean
  square error
  2.DRMS. It is, however, important to note that the
  effectiveness of the relative positioning technique is largely dependent
  on the distance ween the two receivers. If the distance
  ween the receivers increases, the residual errors will become
  larger, and hence the quality of the positioning results degrades.
  This is a limitation of the DGPS technique. In additi
