Embodiment Construction

[0016] refer to image 3 , Figure 4 . The invention takes the quad-core microprocessor of the computer processing module as the core; the microprocessor communicates with other sub-systems and modules through the bus scheduling module; the storage module stores the initial important parameters of the pico-satellite; Provide the voltage required for the chip to work properly. Picosatellite computer system based on quad-core microprocessor of Android mobile phone includes computer processing module, storage module, power management module, bus scheduling module and circuit protection module

[0017] Computer processing module: It mainly includes three parts: commercial quad-core microprocessor, built-in ADC module and built-in power management module. At present, the performance of the on-board microprocessor suitable for most spacecraft data processing applications is relatively low, and the application is limited. Computer systems using high-performance quad-core micropro...

Abstract

The invention relates to a pico-satellite computer system based on a quad-core microprocessor of an android mobile phone, which aims at solving the technical problem of poor information processing capacity of the existing pico-satellite computer system. The pico-satellite computer system adopts the technical scheme that the system comprises a computer processing module, a storage module, a power source management module, a bus scheduling module and a circuit protection circuit, wherein the computer processing module is used for controlling running attitudes, arbitrating states, and sending control commands, and can realize communication with an attitude control system, a communication system, a satellite-borne power source system, the storage module, a function debugging module and a power source protection module through the bus scheduling module. The commercial quad-core microprocessor has the advantages that the power consumption is low, the data processing speed is high, the on-chip available resources are rich, the property is optimum, and the operation temperature meets the requirement of working environment of pico-satellites, so the cost of spacecrafts is reduced, the development and manufacturing period is shortened, and the requirements of small size, low power consumption, high reliability and high data processing speed of the satellite-mounted computer system by the pico-satellites are met.

Description

technical field [0001] The invention relates to a pico-satellite computer system, in particular to a pico-satellite computer system based on a quad-core microprocessor of an Android mobile phone. Background technique [0002] Picosatellites generally refer to small satellites under 1 kg and based on MEMS technology. Picosatellites have outstanding advantages such as low cost, short development cycle, and flexible launch. They can complete tasks that are difficult for a single large satellite by forming constellations, formations, or satellite groups. However, the development of pico-satellite technology in various countries in the world today has put forward more and higher requirements for the on-board computer, which is an important part of the spacecraft platform, such as smaller volume, quality, greater storage capacity, and stronger information processing capacity. . However, due to reasons such as volume, quality, and data throughput, the relatively mature computer s...
