Problems solved by technology

[0005] Domestic micro-nano satellites generally follow the traditional satellite design idea. The on-board computer, attitude and orbit control computer, measurement and control, navigation, data transmission, IO drive, power supply, load interface and data processing are basically separated into several dedicated modules, with varying degrees of integration. High, poor module generalization
[0006] 2. Product customization, poor scalability
[0009] 3. The degree of standardization is low and the degree of batching is weak

Abstract

The invention provides a mini high-functional-density integrated satellite electronic system which is high in functional density, expansibility and standard degree. The system is applied to a 10kg, 50kg or 100 kg micro / nano satellite, and comprises a core board card and an expanded board card which communicate with each other via a high-speed interconnection bus. The expanded board card is connected with satellite hardware equipment via interfaces, concretely, connected with a microwave network interface of a satellite antenna, a load interface of a satellite load, an analog collection interface of a satellite single-end analog collector, an instruction interface of instruction reception, a primary bus interface of a satellite storage battery, a power driving interface of a power driver, aheat control loop interface of heat control equipment and a sensor interface of a sensor. The core board card obtains data of the satellite hardware equipment via the expanded board card to realize functions including satellite affair management, attitude and orbit control, measurement and control, navigation, data transmission and power supply management.

Description

technical field [0001] The invention relates to the professional technical field of on-board integrated electronics and measurement and control. Background technique [0002] Compared with the foreign advanced level, the development status of domestic micro-nano satellite electronic systems mainly has the following gaps: [0003] 1. Low functional density, low degree of miniaturization [0004] Foreign micro-nano-satellite integrated electronic systems represented by OneWeb satellites have realized the integration of functions such as star management, measurement and control digital transmission navigation, and attitude-orbit calculation, achieving the unity of high functional density, low power consumption, and low quality. [0005] Domestic micro-nano satellites generally follow the traditional satellite design idea. The on-board computer, attitude and orbit control computer, measurement and control, navigation, data transmission, IO drive, power supply, load interface an...
