Abstract

The invention provides a consistency verification method for a satellite navigation simulation model. The consistency verification method comprises the following steps: establishing a test task classification model; establishing a test task verification target system according to different attributes of the test task; determining a check object of the test task; defining task evaluation content covering comprehensively; and designing various test tasks according to models and contents involved in the evaluation contents. The invention further provides a system for verifying the consistency ofthe satellite navigation simulation model. The system comprises a satellite model, an application model, a main control station model, a measurement and control station model, a monitoring station model, an injection station model, a combined model management module, a basic module model parameter and attribute configuration module and a test task parameter configuration module. According to the scheme, a top-down simulation verification method can be provided for a satellite navigation simulation model, comprehensiveness of test tasks is guaranteed to the maximum extent, and a verification result can be directly used for optimization and upgrading of a Beidou engineering system.

Description

technical field [0001] The invention mainly relates to the technical field of satellite navigation, in particular to a method and system for verifying the consistency of a satellite navigation simulation model. Background technique [0002] Large-scale and complex satellite networks have large scale, many entities, and extensive services. In order to reduce the operational risk of the real system, the construction of large-scale complex satellite systems is often accompanied by the construction of its digital twin software simulation system to simulate the operation of the real satellite system. The software simulation system has advantages that hardware systems cannot match, such as flexibility, openness, and foresight. However, the software simulation system must first pay attention to the equivalence of the simulation system to the real system. The correctness of the simulation model is directly related to the effectiveness of the entire simulation system. sex. The Beido...
