Embodiment Construction

[0022] The technical solution of the present invention will be further described in detail with specific embodiments below.

[0023] see figure 1 The synchronous control method of the present invention includes three modules: time synchronous setting of digital simulation software, data synchronous control of driving software, and multi-board cooperative work control.

[0024] A. The function of the time synchronization setting module of the digital simulation software is: perform synchronous simulation on multiple frequency points of multiple systems selected by the user, and package and number the one-second control signal generated by the simulation, and finally transmit it downward For mid-range drivers.

[0025] B. The functions completed by the data synchronization control module of the driving software are: due to differences in computer performance, number of frequency points, and initial calculation amounts of different systems, different digital simulation computers...

Abstract

The invention discloses a multi-board synchronous control method of a GNSS signal simulation system, including three modules of digital simulation software time synchronization setting, driving software data synchronous control, and multi-board cooperative work control, so that multi-constellation and multi-frequency point navigation The synergistic generation of signals ensures the time synchronization of the navigation signals of each frequency point generated by the GNSS signal simulation system composed of multiple digital simulation computers, multi-frequency points, and multi-board cards. The method of the present invention can upgrade the platform structure of the GNSS signal simulation system from a singular computer imitation, single frequency point, and single board structure to a plurality of computer imitation, multi-frequency points, and multi-board structures, so that it has the ability to generate compatible and interoperable multiple The function of system multi-frequency point navigation signal is of great significance to GNSS system compatibility performance evaluation test and receiver interoperability test test.

Description

technical field [0001] The present invention relates to a new multi-constellation, multi-frequency point navigation signal collaborative generation method, more specifically, a GNSS signal simulation system composed of a plurality of imitation computers, multi-frequency points, and multi-board cards to collaboratively generate multi-constellation , The method of multi-frequency point navigation signal. Background technique [0002] GNSS is the abbreviation of Global Navigation Satellite System, and the Chinese name is Global Navigation Satellite System. [0003] In order to accurately simulate, verify and evaluate multi-constellation GNSS compatibility and interoperability, multi-constellation and multi-band navigation signals need to be generated synchronously. For the GNSS signal simulation system composed of most computer-like, multi-frequency points, and multi-board structures, in order to make multi-constellation, multi-frequency point navigation signals collaborativel...
