Determining the integrity of navigation signal in a multi constellation navigation receiver SNA

This report examines the concept of integrity of navigation signals and its impact on equipment users of satellite navigation systems. The sources of data integrity for multi constellation receiver GALILEO / GPS / GLONASS / SBAS, developed by «Orizon-Navigation», and «KB Navis» in the framework of the implementation of the project Galileo were reviewed.

The using satellite navigation systems as the primary means of navigation on the accuracy of the coordinates is superimposed a number of requirements that can not be guaranteed throughout the entire session (positioning). Failures of satellite or terrestrial systems may lead to the fact that the navigation receiver will use the data which contain errors and calculate the coordinates of the level of accuracy in excess of allowable value for your application.
