Abstract
The present invention consists of a method to ensure the integrity of the navigation solution even when the user is in a non controlled environment as it is the case of urban and road applications. The method requires the existence of a Signal In Space with guaranteed integrity as the one today provided by SBAS systems or from GBAS, Galileo or GPS-III in the future. The invention covers the algorithms to detect and isolate errors present in non controlled environments such as multipath and compute resulting position error bounds with the required level of integrity. This invention substantially increases the field of application of satellite navigation systems with associated integrity to the so-called liability critical applications.
