Embodiment Construction

[0021] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0022] The system consists of a system operation control center, N navigation sources (N≥3) and a dedicated navigation terminal. The user realizes positioning and timing by receiving navigation signals from M navigation signal sources. The accompanying drawings are examples for illustration. Four navigation sources are designed in the embodiment of the drawings.

[0023] The specific implementation steps are as follows:

[0024] (1) The system operation control center generates the original message information {M1_a, M2_a, M3_a, M4_a} of multiple navigation sources. The original message contains the reference position information of each navigation source and other information necessary to complete positioning and timing; and multiple The navigation source performs mixed encoding processing on the original message information flow {M1_a, M2_a, M3_a, M4...

Abstract

The invention provides a design method of a distribution typetrusted radio navigation system architecture for situations where current radio navigation systems are susceptible to fraudulent interference. The method designs navigation system compositions and navigation signal generation and transmission and reception methods, achieves effective resisting on the navigation spoofing means and the like through improving the system architecture and the signal broadcasting mode of the radio navigation system, thereby greatly improving the safety of the radio navigation system including satellite navigation.

Description

technical field [0001] The invention relates to the field of satellite positioning and navigation technology and communication, in particular to a method for designing a distributed trusted radio navigation system architecture. Background technique [0002] After years of development, radio navigation with satellite navigation and ground-based navigation as the main application forms has been widely used in various industries of the national economy and military operations, and has played an important role. [0003] Radio navigation has outstanding advantages such as wide service range, high navigation and positioning accuracy, and convenient use. The most widely used satellite navigation system can provide full-time continuous positioning, timing and navigation services for the whole world by broadcasting navigation signals through dozens of satellites deployed in space orbit. While the navigation and positioning based on the radio system has the above-mentioned outstandin...
