Problems solved by technology

The debugging and testing of application software is an extremely important and long-term part of the development of the spaceborne aircraft, which has caused delays in the development of the spaceborne aircraft.
This serial development mode is increasingly incompatible with the fast and good development trend of microsatellites

Embodiment Construction

[0021] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.

[0022] The micro-operating system of the present invention is formed as attached figure 2 As shown, it includes three parts: system operation, system management, and test support.

[0023] Among them, the system operation consists of four parts: CPU initialization and setting module, interface initialization and setting module, clock initialization and setting module, and trap initialization and setting module. The CPU initialization and setting module is responsible for the initialization of CPU registers and CPU-related state settings; the interface initialization and setting module is responsible for interface initialization and setting of interface-related states; the clock initialization and setting module is responsible for the setting of real-time clock and general clock; trap initialization and setting Responsible for trap initializat...

Abstract

The invention provides a building method of a micro-operating system for microsatellite onboard apparatuses. The micro-operating system built by the building method is task independent; the problem that onboard apparatus application software is unable to be debugged and tested when development of onboard system software is not in place can be solved; the micro-operating system provides a running environment for the onboard apparatus application software (such as housekeeping software and attitude and orbit control software; each piece of application software is imparted respective development debugging and testing conditions; parallel development of the microsatellite onboard apparatus software is guaranteed; the contradiction between high quality of microsatellite software products and short development cycle of software is effectively overcome; the ability to quickly develop microsatellites is effectively improved.

Description

technical field [0001] The invention relates to the technical field of micro-satellites, in particular to a method for constructing a micro-operating system of a micro-satellite. Background technique [0002] Micro-satellite on-board software mainly includes three parts: system software, star software and attitude control software. Among them, the system software belongs to the operating system software, which is responsible for interacting with the hardware of the spaceborne aircraft, providing an operating environment for application software (including star software and attitude control software), and responsible for many tasks such as fault handling. attached figure 1 Shown is a schematic diagram of the composition of the microsatellite onboard aircraft system. Compared with the system software that can run directly on the hardware of the spaceborne aircraft, the star mission software and attitude control software as application software do not have the ability to run ...
