For example, some operations / steps can be decomposed, and some operations / steps can be combined or partially combined, so the actual execution order may change according to actual conditions.

[0037] In order to achieve the above technical effects, this embodiment Figure 1 A rocket launch simulation method based on rocket satellite telemetry data is provided, comprising:

[0038] Use the initialization environment to obtain geographic information; the obtained geographic information includes map data, terrain data and spatial environment information. At the same time, the geographic information is hierarchically managed according to the map and terrain levels, and the hierarchically managed resources are published in the local area network through links. As resource sharing, it can be directly used by other systems that need to obtain geographic information, completing the construction of shared resources for all geographic information. At the same time, various types of map slice skins are provided, and map skins can be selected according to the display style when displaying;

[0039] Obtain mission information and telemetry parameters for rocket launch;

[0040] The mission information of the rocket launch is obtained through the mission information table, as shown in Table 1 below;

[0041] Table 1 is the task information table

[0046] Use the acquired task information to acquire T0, important events, and model data; after acquiring T0, compare it with the theoretical T0. When there is an actual T0, it is judged to be more detailed, and it is necessary to re-acquire important events and T0, that is, it is necessary to re-acquire the task information, re-acquire T0 and important events from the task information, and push the acquired important events to the display end for display. The display end distinguishes between important events that have occurred, have not occurred, and are in progress.

[0047] And obtain the loading model according to the acquired model data; the loading models in this embodiment are rocket models and satellite models. Before obtaining the loading model, a loading model library is first established. The model library includes loading models corresponding to different model data. When obtaining the loading model, the model data is input into the model library to match the corresponding loading model (rocket model and satellite model). This technology belongs to the common knowledge in the technical field and will not be described in detail here.

[0048] The launch scene model is built using the acquired geographic information. When building the scene model, a simulation scene model is produced based on the environmental characteristics of each rocket launch site in the country. The produced scene model has the advantages of being vivid, realistic, and easy to identify the location of the launch site.

[0049] The telemetry parameters are bound to important events. In this embodiment, the telemetry parameters are bound to rocket key events (important events). The purpose of binding is to find the relationship between the telemetry parameters and the rocket key events. For example, when the telemetry parameter is A, the rocket key event should be B. After the binding is completed, the corresponding telemetry data is obtained, and the corresponding telemetry parameters are obtained using the telemetry data. When the telemetry parameters meet the conditions, that is, the corresponding rocket key event is triggered, the trigger model is driven to perform the same action as the key event to complete the launch action of the rocket model, and each key event is used to complete the launch simulation of the entire rocket model. The simulated animation is displayed through the display end.

[0050] like Figure 2 A rocket launch simulation device driven by rocket satellite telemetry data includes:

[0051] Geographic information unit is used to manage maps, terrain data, and spatial environment information. The geographic information unit manages hierarchically according to the map and terrain levels, and publishes the hierarchically managed resources in the local area network through links. As resource sharing, it can be directly used by other systems that need to obtain geographic information, completing the construction of shared resources for all geographic information. At the same time, it provides multiple types of map slice skins, which can be selected according to the display style when displaying;

[0052] The basic information management unit is used to configure and manage the obtained loading model, scenario model, key time, T0 and telemetry parameters, and use the obtained T0 to determine whether to update the information of important events. If it is necessary to update, the obtained information of important events is updated; the updated information of important events includes occurred, not occurred and in progress;

[0053] The telemetry processing unit is used to receive the telemetry data, parse the telemetry data according to the byte position of the telemetry code value in the telemetry table and the telemetry processing formula, and translate the parsed telemetry parameter value;

[0054] The simulation unit is used to bind telemetry parameters with important events. When the obtained telemetry parameters meet the requirements of triggering important events, the action of the important event is triggered and loaded into the loading model.
