DEVICE FOR PROCESSING NAVIGATION DATA OF A SATELLITE NAVIGATION SYSTEM FOR DELIVERING INTEGRITY AREA MAPS
First Claim
1. A device (PD) for processing navigation data related to satellites in a satellite navigation system orbiting around a heavenly body, characterized in that it comprises processing means (PM) configured to compare integrity data (ID) representative of reliability values for corrections of errors in the orbital positioning and/or synchronization of said satellites, to at least one selected set of N selected threshold values, N being an integer greater than or equal to one, in such a way as to deliver at least one group of cartographic data representative of at most N+1 geographic areas defined with respect to said heavenly body and in which said integrity data is less than said N threshold values of said selected set, greater than said N threshold values of said selected set Si, or between two threshold values of said selected set.

Abstract
A device (PD) is dedicated to processing navigation data related to satellites in a satellite navigation system in orbit around a heavenly body. This device (PD) comprises processing means (PM) tasked with comparing integrity data (ID), which represents reliability values of corrections to errors in the orbital positioning and/or synchronization of the satellites, to at least one selected set of N selected threshold values, N being an integer greater than or equal to one, in such a way as to deliver at least one group of cartographic data representative of at most N+1 geographic areas defined with respect to said heavenly body and in which said integrity data is less than the N threshold values of the selected set, greater than the N threshold values of the selected set Si, or between two threshold values of the selected set.
