Mobile positioning via fusion of mixed signals of opportunity

  title={Mobile positioning via fusion of mixed signals of opportunity},
  author={Chun Yang and Thao Nguyen and Erik Blasch},
  journal={IEEE Aerospace and Electronic Systems Magazine},
In this article, we investigated several SOOPs for mobile positioning without GPS and compared their signal characteristics for navigation and tracking. Critical issues in positioning with SOOP were discussed, which include the lack of independent SOOP (poor GDOP), SOOP clock errors, 2-D vs. 3-D solutions, multipath and NLOS signals, and signal integrity, among others. We described the development of mobile test-beds with hardware and software features and presented field test results. The… CONTINUE READING
