Aircraft steering assistance system for global navigation satellite system based landing system, has multimode receivers with digital processing cards, where elaboration function of guiding data is distributed on reference modules and cards

摘要

The system has an inertial reference system including reference modules (ADIRU 1-ADIRU 3). Multimode receivers provide guiding signals and global navigation satellite system (GNSS) data. Each receiver has digital processing cards with a function of mutual control of data elaborated by the cards. An elaboration function of guiding data from the GNSS data and inertial data at detection of faults is distributed on the modules and cards. An independent claim is also included for a utilization of a steering assisting system in an aircraft, for implementation of global navigation satellite system (GNSS) based landing system (GLS) guiding with inertial improvement for approach operations of categories I to III.
