<p>The method involves determining errors caused during determination of a pseudo rank between satellites (14) and observation areas (22), where the errors influence integrity of a satellite navigation system (10). Error budgets are formed for different categories of the errors, and the error budgets are transmitted to a utilization system (18) using a navigation signal (16) of the satellites over earth stations. The signal is received by the utilization system, and the integrity of the navigation system is evaluated based on the error budgets present in the received signal. Independent claims are also included for the following: (1) a utilization system for measuring integrity of a satellite navigation system (2) a device for enhancing integrity communication of a satellite navigation system comprising a unit for determining errors.</p> |
