The study of error sources for MOSAIC/DME system: A single station based positioning system for APNT
This paper presents a new kind of navigation system, a single station based 3-dimensional positioning system, named MOSAIC/DME. Particularly, its possible error sources, such as tropospheric delay, antenna misalignment and multipath are studied and applied to simulations for understanding and verification of this system. For tropospheric and multipath simulations, WAAS tropospheric model and ray-tracing approach are applied respectively. The results present that MOSAIC/DME system is vulnerable to small errors in signal, because of the bad geometry using only a single station for positioning. But this system also has its own advantage to treat those errors.
