Embodiment Construction

[0087] In the present invention, a method for allocating indicators of a communication satellite service interruption caused by a space single event event, the steps are as follows:

[0088] Step 1, determine the subsystems and stand-alone single-particle sensitive devices and protective measures that affect the continuity of satellite business;

[0089] Step 2, calculating and obtaining the weight of the single event flipping of products at all levels of the satellite system;

[0090] Step 3, determine the short-time interruption index of the satellite system service;

[0091] Step 4, allocate short-term interruption indicators of satellite services for subsystems and stand-alone products.

[0092] The concrete process of described step one is:

[0093] 11) According to the satellite business requirements, sort out the subsystems and stand-alone machines that may cause short-term interruption of the satellite business, and make preliminary statistics on the number of space ...

Abstract

The invention discloses an index distribution method for communication satellite service interruption caused by a space single event. On the basis of fully considering the complexity of each single machine and each device and the single particle protection capability, index distribution is carried out according to the weight of each level of product, and the indexes of the number of times of service interruption allowed by a user are decomposed step by step into subsystems, single machines and bottom layer components. According to the method, the complexity and the single particle protection capability of each single machine and each device are fully considered, index distribution is performed according to the weight of each level of product, main factors influencing the whole satellite service are focused, and the rationality of index distribution and the design realizability are ensured. According to the method, overall designers are helped to decompose the requirements of users on service continuity into specific design indexes which can be operated by single machine and component designers, and landing and implementation of the requirements of the users and subsequent design verification are facilitated.

Description

technical field [0001] The invention belongs to the technical field of allocation of communication satellite service interruption indicators, and in particular relates to an index allocation method for communication satellite service interruption caused by space single event events. Background technique [0002] With the development of satellite communication technology, satellite users have higher and higher requirements for communication capacity, speed, and security. The risk of user business interruption is greatly increased. [0003] At present, the reliability indicators of communication satellites are mainly life and reliability. Satellite systems, sub-systems, stand-alone machines and even components all have clear requirements for reliability indicators. However, under mission environment conditions, the existing reliability indicators of components mainly consider the random occurrence of non-recoverable permanent faults, but the space radiation related to single-...
