Description

Technical Field

[0001] The present invention relates to the field of spatial information analysis, and particularly relates to a method for implementing a satellite simulation event manager based on multiple spatial events. Background Art

[0002] In the current increasingly complex space environment, each country is committed to developing its own giant constellation. This requires considering events such as spacecraft collisions, sub-satellite separation, satellite maneuvering orbit change, or satellite disintegration. On this premise, the ability to perform deduction and event management in a simulation environment is required.

[0003] Currently, when creating an event, generally, an event is directly created for a single object without managing the event time and the whole, and the specific parameters of the event creation cannot be viewed. It is very inconvenient for modifying subsequent events and event backtracking. Therefore, there is an urgent need for research on a manager that can manage and query events as a whole, view the distribution of different events on the time axis, and view the execution status of specific events in the event list. Summary of the Invention

[0004] To solve the existing problems, the present invention provides a method for implementing a satellite simulation time manager based on multiple spatial events. The specific scheme is as follows:

[0005] A method for implementing a satellite simulation time manager based on multiple spatial events, comprising the following steps:

[0006] S1, create an event list by obtaining events;

[0007] S2, perform grouped judgment on the event list, and respectively enter the operation in step S3A - satellite platform service and the operation in step S3B - device service;

[0008] S3A, if it is an event list of a satellite object, perform operations for satellite object events;

[0009] S3B, if it is an event list of a device object, directly pass it into the event management service for the next operation;

[0010] S4, in the event management service, create and store an event time axis for display according to time and real-time update of the event status at the front end;

[0011] S5, save another event time axis in the event management for event iteration driven by time;

[0012] S6. In time-driven event judgment, to avoid repeated loop judgments during event judgment, after arranging in sequence according to time, during event loop, if an event is less than the current time, execute and delete the current event, and jump out of the current event loop.

[0013] Preferably, step S3A specifically includes the following steps:

[0014] S3A1. Traverse the event list of the satellite object in a loop;

[0016] S3A3. Perform satellite-related operations according to the type of the event, calculate the corresponding orbit after the satellite event operation, and add the calculation result to the event list.

[0017] Preferably, the types of the satellite object events in step S3A2 include satellite orbit change events and satellite disintegration events.

[0018] Preferably, step S3A3 is specifically: perform orbit change or disintegration of the satellite, then calculate the orbit after the satellite orbit change or the orbits of the debris after the satellite disintegration, and add the above calculation results to the event list.

[0019] The present invention also discloses a computer-readable storage medium, on which a computer program is stored. After the computer program runs, it executes the method as described above.
