Abstract

The invention discloses an integrated data acquiring and processing system of multi-source aviation navigation signals, belonging to the technical field of combination navigation and flight check. The system mainly comprises a signal acquiring and pre-processing sub-system, a signal evaluation and multivariate graph display module and a navigation signal simulation sub-system, wherein the navigation signal simulation sub-system is used for sending analogue signals to the signal acquiring and pre-processing sub-system; the signal acquiring and pre-processing sub-system communicates with the signal evaluation and multivariate graph display module through a network communication module; and various navigation data blocks transmitted by the signal acquiring and pre-processing sub-system are analyzed and processed, so that error and tolerance results of the navigation signals are obtained. By utilizing modular design, the integrated data acquiring and processing system disclosed by the invention has the advantages of being flexible for construction and strong in expansibility; and functions of the integrated data acquiring and processing system of the multi-source aviation navigation signals can be extended conveniently, so that acquisition support on novel navigation signals is provided.

Description

technical field [0001] The invention belongs to the technical field of integrated navigation and flight verification, and specifically relates to a comprehensive data collection and processing system for multi-source aviation navigation signals. The system can collect ILS, VOR, DME, GPS, VDB, inertial navigation and atmospheric data, etc. A kind of aviation navigation signal is provided to the application layer for further processing in a unified data format and flexible interface. Background technique [0002] There are a variety of radio systems currently used in aviation navigation, including the VHF omnidirectional beacon system (VOR) for providing azimuth information, the range finder (DME) for providing distance information, the Tacan system (TACAN), Instrument Landing System (ILS), inertial navigation system, and GPS-based satellite navigation system developed in the last 20 years to provide glide path and glide slope information. Because a specific navigation system...
