Communication Satellite Location /Cell Location integrated navigation system for all-blind war

The Communication Satellite Location/Cell Location (CSL/CL) integrated navigation system will play key role in all blind war. Recent studies show the CSL can provide location services and satellite communication services. However, CSL can not provide reliable and continuous information at any time, because its signals are often screened or disturbed when the users are in the urban canyon, tree-covered areas, or tunnels. CL aware services are becoming attractive with the deployment of next generation wireless networks and broadband wireless networks especially in indoor and city areas. In addition, Cell network have the greatest strength and coverage of signals in the all blind war. We improve the LS algorithm in the system and the Robust Least Squares algorithm is used to deal with the observations of CSL/CL integrated navigation system in the article. It is shown, the CSL/CL integrated navigation system, can not only provide continuous information at any time, but also the new algorithm controls the influences of measurement outliers of field strength measuring.
