The application of wavelet analysis technology on GPS data processing
He Feng · Cehui kexue · 2009
Recently,wavelet analysis technology has been widely applied in many technology area such as data processing,image processing,sound identification and synthesis,celestial bodies recognition,machines vision,default diagnosis and monitoring.Because there exist some errors in data gathering and processing in GPS dynamic surveying,these errors will affect the precision of the surveying,it is a big issue to eliminate these errors to improve the results.In this paper,two NovAtel DL-4 plus GPS receivers were used tto design the GPS kinematic experiments based on dynamic inspection platform.The GPS data was processed by GrafMov data processing software.Then the result was denoised with wavelet technology,the distribution and characteristic of the noise signals were obtained.In the ends,the influence of this noise was evaluated and analyzed.
