| 20110231038 | AIRCRAFT LANDING SYSTEM USING RELATIVE GNSS - A method for confirming mobile base station integrity in a relative GNSS aircraft landing system, the method comprising: determining a relative position of a first GNSS antenna fixed to the mobile base station with respect to a second GNSS antenna also fixed to the mobile base station by processing signals from a GNSS satellite constellation; calculating a distance between the first GNSS antenna and the second GNSS antenna using the measured relative position; comparing a calculated distance to a known fixed distance; and confirming mobile base station integrity if the calculated distance is within a predetermined threshold of the known fixed distance. | 09-22-2011 |
