A Research on All Source Navigation and Positioning and Its Critical Technology

摘要

Due to the increased complexity of the application scenario, the conventional navigation and positioning system, which uses a single method, can't meet the challenge of accuracy and reliability. Comparing with multi-sensor fusion, All Source Navigation and Positioning (ASPN) provides an all-in-one solution. It uses a uniform architecture to achieve data fusion of numerous sensors and data filtering with the ability of re-configuration. It tries to provide the maximum accuracy and reliability when some navigation and positioning methods, especially the GNSS, are not available. This paper mainly introduces the ASPN's concept and its development status. It also analyses and predicts the critical technology of ASPN.
