Embodiment Construction
[0139] The present invention will be described in detail below with reference to the accompanying drawings and examples.
[0140] A method for comprehensive evaluation of system effectiveness of a navigation constellation of the present invention, the steps are as follows:
[0141] (1) According to the operating characteristics of the navigation constellation, the performance of the navigation constellation system is divided into the performance of the single-star system and the logical relationship between the stars. The performance of the navigation constellation system is a comprehensive function of the performance of the single-star system and the logical relationship between the stars;
[0142] (2) Determine the single-track availability A according to the navigation satellite outage status and status parameters SLOT (t), according to the single-star fault type and fault parameters to determine the single-star reliability R NAV (t), determine the single-star capability C...
