Evaluation of GPS Baseline Quality Based on Probabilistic Characteristic of Integer Ambiguity

  • Received Date: 16 Nov 2006
  • Publish Date: 25 Dec 2007
  • To simplify the evaluation of GPS(global positioning system) baseline quality,a closed-form probability density function(PDF) of fixed GPS baseline solution was presented,and the effects of some factors influencing the PDF of fixed GPS baseline solution,such as the integral region of the PDF,the precision of ambiguity float solution,the precision of baseline float solution and the correlation coefficient of the two solutions,on the improvement of GPS baseline quality were discussed through numerical analyses.The experimental results show that the precisions and correlation coefficient of the ambiguity float solution and the baseline float solution have a great effect on GPS baseline quality,and the precisions of the two solutions have a positive effect on the improvement of GPS baseline quality,while their correlation coefficient has a negative effect.
