查看航天器上的处理器的源代码

== 概述 ==

空间环境对电子信号的最大威胁就是电离辐射，其能使本来是1的数字信号“翻转”变成0，反之亦然

因此航天处理器的主要性能指标就是抗辐射性、容错性，还有就是可靠、稳定

=== Mongoose-V ===

;Feature:

<pre>
        Radiation hardened
        10~15 MHz version of the MIPS R3000
        Developed by Synova, Inc.
</pre>


;Applications:

* NASA's Earth Observer 1 (EO-1) satellite (launched in Nov. 2000) --- Main flight computer
* NASA's Microwave Anisotropy Probe (MAP), (launched in June 2001) --- Main flight computer similar to that on EO-1.
* NASA's three microsatellites of Space Technology 5 (ST5) (launched in Mar. 2006) --- Onboard flight computer (the Command & Data Handling system)
* NASA's New Horizons spacecraft --- Two computer system, the Command and Data Handling system and the Guidance and Control processor. Each of the two systems is duplicated for redundancy, giving a total of four computers.
