Embodiment Construction

[0014] The present invention will be described in further detail below in combination with specific implementation examples and accompanying drawings.

[0015] figure 1 It is a three-level structural diagram of the navigation signal simulator, which adopts a three-level structure of "system-component-unit", in which several core units with identical hardware structures constitute the functional core of core components, and several core components with identical hardware structures constitute satellites. The functional core of the navigation signal simulator system.

[0016] figure 2 It is a schematic diagram of the system composition structure. The VXI chassis is the hardware platform of the system, which provides the power management required by each board module and the floor switching bus, and completes the management and control of each board module together with the zero-slot board. VXI bus technology is developed on the basis of VME, the size is larger than VME, and t...

Abstract

The invention provides a hierachical structure and an implementing method thereof for a satellite navigation signal simulator. The structure of the navigation signal simulator is divided into three layers of a system, components and units, a functional core of the system is composed of a plurality of core components with same structures, and the functional core of each core component is composed of a plurality of core units with same structures. The implementation method includes that the system is divided according to function modules and integrated on different board cards, and the f board cards are inserted into a (VXI) bus case form the navigation signal simulator. The navigation signal simulator comprises a plurality of navigation radio frequency signal simulation core components and basic components (including a C size 13-slot VXI case, a 0-slot control card, an optical fiber interface card, a time-frequency component and two signal synthesis and power control components.

Description

technical field [0001] The invention relates to the field of satellite navigation instruments, mainly to the field of design and production of a navigation signal simulator, and relates to a hierarchical structure and realization of a satellite navigation signal simulator. The invention can be applied to the design and realization of a satellite navigation signal simulator. Background technique [0002] The satellite navigation signal simulator is a key instrument in the development of satellite navigation systems and various receiving equipment (especially high dynamic receivers), and has always been concerned by the military and industrial sectors. The use of satellite navigation signal simulators for detection and calibration has become an internationally recognized best method. Satellite navigation signal simulators have been widely used in academic and industrial fields, and have entered many different applications, including military or civilian Purposes of navigation...
