Abstract

The present invention provides an intelligent satellite platform system and on-orbit application expansion method. The system comprises: an embedded processor configured to operate a real-time embedded operation system; an application processor configured to operate a multi-task intelligent operation system and a user defined application program, wherein the intelligent operation system comprises process management, memory management and file management functions, and the intelligent operation system provides the support of process scheduling, memory management and file system and network interfaces, the application programs are mutually called through communication between the processes, the application programs call the interfaces provided by the operation system through calling of the system; and a CAN bus, wherein the embedded processor and the application processor are connected with the CAN bus. User can perform development of application programs on the ground according to their requirements, and the application programs are installed on the satellite through a satellite communication network so as to realize the infinite extension and flexible configuration of the satellite functions and realize redefinition of the on-orbit satellite function and software upgrading of the on-orbit satellite.

Description

technical field [0001] The present invention generally relates to the technical field of satellite platforms, and more specifically, relates to the application extension technology of in-orbit satellites. Background technique [0002] The traditional satellite platform design idea is to use information bus and energy bus to form a network, and the form of each equipment node and the on-board network form a function-intensive and flexible distribution system structure. The star management software is the control and command center of the entire satellite operation, and the on-board operating system is the platform for the development and operation of the entire star management software. [0003] The traditional on-board operating system generally uses an embedded real-time operating system, which has the characteristics of miniaturization, strong real-time performance, high stability, tailorable, and solidified codes. However, such an operating system and architecture have t...
