At present, in the traditional satellite test, due to the reasons of tight coupling of software and hardware of a satellite and the like, a set of software execution environment which is the same as that of an orbiting satellite cannot be provided in a pure software mode, the test can be carried out only by depending on a physically or semi-physically simulated desktop satellite, and due to the fact that the simulator has different operation environments and different operation modes, the problem of inconsistent integration degree exists.

Based on the virtual satellite, the test platform based on the software and the algorithm of the virtual satellite and the method, provided by the embodiment of the invention, the virtual satellite program execution environment is completely compatible with the orbiting satellite, and the test platform is provided with a plurality of background simulation programs and load simulators, so that an operation view consistent with that of a real satellite is provided for an application program. The virtual satellite testing environment can be loaded and operated as required, the testing requirements of multi-region cooperation, distributed execution and large-scale parallel are met, and the problems that the desktop satellite in the prior art is high in manufacturing cost and limited in quantity and cannot meet the testing work of multi-region cooperation, distributed execution and large-scale parallel are solved.
For the convenience of understanding the present embodiment, a detailed description will be given to a virtual satellite disclosed in the present embodiment.
The first embodiment is as follows:
the present embodiment provides a virtual satellite, a schematic structural diagram of which is shown in fig. 1, and the virtual satellite includes: the system comprises a satellite platform simulator 120, a cloud computing platform simulator 110 and a load simulator 130, wherein the cloud computing platform simulator 110 is connected with the satellite platform simulator 120 through a data center 140, and the cloud computing platform simulator 110 is decoupled from the satellite platform simulator 120 and the load simulator 130 by taking the data center 140 as an interface.
The cloud computing platform simulator 110 is used for providing the same basic service as the in-orbit satellite and reading satellite platform data and load data;
a satellite platform simulator 120 for simulating a satellite platform system and outputting satellite platform data;
and a load simulator 130 for simulating the payload system and outputting the payload data.
Specifically, the cloud computing platform simulator 110 interacts data and instructions with the satellite platform simulator 120 and the load simulator 130 through the data center 140. In practical applications, the data center 140 may include a database for simulating an integrated unit portion of a real satellite, directly receiving or reading externally stimulated data. The data center 140 releases the coupling relationship between the satellite platform simulator 120, the load simulator 130 and the cloud computing platform simulator 110, so that the parts except the cloud computing platform are integrated into the virtual satellite as components, and the problem of inconsistent integration degree caused by different simulator operating environments and different operating modes is solved.
Both the satellite platform simulator 120 and the load simulator 130 can simulate satellite platform systems and payloads with different capabilities according to certain configuration parameters, thereby defining satellite services for different types of software. The simulators are designed in a plug-in mode, a simulator interface is defined by using a database, and the simulators are used as plug-in components, so that the simulators can be customized independently and can be used in a plug-and-play mode, and the application convenience of the simulators in the simulated satellite is greatly improved.
In practical application, the satellite platform mainly has the functions of thermal control, power supply, attitude and orbit control, measurement and control, data management and the like.

In some implementations, referring to another structural schematic diagram of the virtual satellite shown in fig. 3, the cloud computing platform simulator 110 may be a Sputnix virtual machine that provides a certain basic service based on a Sputnix system, and the coupling relationship between software and hardware of the satellite may be released through the Sputnix virtual machine, so that the cloud computing platform simulator 110 may be free from the limitation of the satellite hardware and provide an execution environment that is fully compatible with the software-defined satellite in an in-orbit flight. The Sputnix virtual machine is loaded with the same basic services as the orbiting satellite, such as measurement and control services, monitoring management services, data transmission services, injection services, platform data services, camera services and the like.
Considering that the testing process of the software and algorithm to be tested is not related to the data forwarding link, the present embodiment may use the data center 140 (in the present embodiment, the data center 140 is a database) to simulate the acquisition unit portion of the real satellite, and directly receive or read the preset external excitation data of the measurement and control data transmission simulator 150, the imaging load simulator 131, the satellite platform simulator 120, and the like by the database.
For example, the imaging payload simulator 131 may send the imaging payload data to a database through a camera service; the satellite platform simulator 120 may send the satellite platform data to the database through a platform data service; the database can transmit data transmission data to the measurement and control data transmission simulator 150 through data transmission service; the measurement and control data transmission simulator 150 can transmit the measurement and control instruction to the database through the measurement and control service; the database may also interact with the satellite platform simulator 120, the cloud computing platform simulator 110, and the load simulator 130 for data instructions through software/algorithms, monitoring management services, injection services, and the like.
In the embodiment, the data center 140 releases the coupling relationship between the satellite platform simulator 120, the imaging load simulator 131 and the cloud computing platform simulator 110, so that the parts except the cloud computing platform are integrated into the virtual satellite as components, and the problem of inconsistent integration degree caused by different running environments and running modes of the simulators is solved.
