Abstract
A method includes obtaining position information of a first vehicle collected in real time by a first positioning system during a first trip on a route, post-processing the collected position information to determine corrected position data of the first vehicle during the first trip, computing position errors of the first positioning system at a plurality of locations during the first trip, determining integrity performance of the first positioning system at the plurality of locations, and providing the integrity performance of the first positioning system at the plurality of locations to the first vehicle or a second vehicle for determining real-time integrity performance of the first positioning system on the first vehicle or a second positioning system on the second vehicle at the plurality of locations.
