Embodiment Construction

[0016] like figure 1 As shown, it is a data flow diagram of the satellite orbit attitude visualization three-dimensional display method of the present invention, and the main steps are as follows:

[0017] (1) Set up the network address and port of the database server; the database server mainly stores the various components in the whole star state, including the 3DS model of the east / west / south / north plate of the satellite, the 3DS model of the center bearing tube, the thrust 3DS model and installation location coordinates of the controller, 3DS model and installation location of the gyroscope, 3DS model and installation location of the momentum wheel, 3DS model and installation location of the solar panel drive mechanism, 490N engine and installation location. The 3DS model here is directly converted from the satellite 3D mechanical model through Deep Exploration software;

[0018] (2) Build a 3D model, read the 3DS model in the database, check whether the model is complete...

Abstract

Provided is a satellite orbit gesture visual three-dimensional displaying method. The satellite orbit gesture visual three-dimensional displaying method comprises the steps: (1) building a three-dimensional model, reading a 3DS model in a database, checking whether models are complete or not, sending the 3DS model to a state display if the models are complete, and if the models are not complete, building relevant models, and sending a data request data package to a server and receiving the data request data package at the same time; (2) checking and comparing data in the data package, finding out data needed by the state display, analyzing the data, and dividing the data into two parts, wherein one part of data are ground equipment data, and the other part of data are on-star remote sensing data; (3) for the ground equipment data, extracting time information, calculating sun and moon ephemeris, and calculating the positions of the sun, the earth and the moon, satellite orbit data and the like to be sent to the state display; (4) for the on-star remote sensing data, classifying the data into three types to be displayed, wherein one type of data are health state data, one type of data are component power source state data, and another type of data are gesture information. The state display adopts the OpenGL to carry out three-dimensional model drawing and display.

Description

technical field [0001] The invention belongs to the field of comprehensive ground testing of spacecraft, relates to a three-dimensional display method using OpenGL and 3DS import technology, and is suitable for applications such as satellite orbit design, satellite attitude simulation and dynamic simulation demonstration. Background technique [0002] The comprehensive test is an experimental verification method after the satellite assembly is completed. Through the comprehensive test, it can be realized to verify whether the satellite interface characteristics, functional characteristics and status meet the design requirements. At present, the comprehensive test of the satellite control and propulsion subsystem is to execute the subsequent test instructions after manual interpretation of the telemetry data. If the three-dimensional display technology is used, the current attitude state and orbit change state of the satellite can be intuitively displayed, and at the same tim...
