U.S. Marine Corps Wants to Change OS for Radar System from Windows XP to Linux
|
||||
================================================================================
|
||||
**A new radar system has been sent back for upgrade**
|
||||

> When it comes to stability and performance, nothing can really beat Linux. This is why the U.S. Marine Corps leaders have decided to ask Northrop Grumman Corp. Electronic Systems to change the operating system of the newly delivered Ground/Air Task-Oriented Radar (G/ATOR) from Windows XP to Linux.
|
||||
|
||||
The Ground/Air Task-Oriented Radar (G/ATOR) system has been in the works for many years and it's very likely that when the project was started, Windows XP could have been considered the logical choice. In the mean time, things changed. Microsoft has pulled the support for Windows XP and very few entities still use it. The operating system is either upgraded or replaced. In this case, Linux is the logical choice, especially since the replacement cost are probably much smaller than an eventual upgrade.
|
||||
|
||||
It's interesting to note that the Ground/Air Task-Oriented Radar (G/ATOR) was just delivered to the U.S. Marine Corps, but the company that built it chose to keep that aging operating system. Someone must have noticed the fact that it was a poor decision and the chain of command was informed of the problems that might have appeared.
|
||||
|
||||
### G/ATOR radar software will be Linux-based ###
|
||||
|
||||
Unix systems, like BSD-based or Linux-based OSes, are usually found in critical areas and technologies that can't fail, under any circumstances. That's why most of the servers out there are running Linux servers, for example. Having a radar system with an operating systems that is very unlikely to crash seems to fit the bill perfectly.
|
||||
|
||||
"Officials of the Marine Corps Systems Command at Quantico Marine Base, Va., announced a $10.2 million contract modification Wednesday to the Northrop Grumman Corp. Electronic Systems segment in Linthicum Heights, Md., to convert the Ground/Air Task-Oriented Radar (G/ATOR) operator command and control computer from Windows XP to Linux. The contract modification will incorporate a change order to switch the G/ATOR control computer from the Microsoft Windows XP operating system to a Defense Information Systems Agency (DISA)-compliant Linux operating system."
|
||||
|
||||
'G/ATOR is an expeditionary, three-dimensional, short-to-medium-range multi-role radar system designed to detect low-observable targets with low radar cross sections such as rockets, artillery, mortars, cruise missiles, and UAVs," reads the entry on [militaryaerospace.com][1].
|
||||
|
||||
This piece of military technology, the Ground/Air Task-Oriented Radar (G/ATOR) was first contracted from the Northrop Grumman Corp. back in 2005, so it's easy to understand why the US Marines might want to hurry this up. No time frame has been proposed for the switch.

美国海军陆战队想把雷达操作系统从Windows XP换成Linux
|
||||
================================================================================
|
||||
**一个新的雷达系统已经被送回去升级了**
|
||||
|
||||

>一谈到稳定性和性能，没什么能真的比得过Linux。这就是为什么美国海军陆战队的领导们已经决定让Northrop Grumman Corp. Electronic Systems把新送到的地面/空中任务导向雷达（G/ATOR）的操作系统从Windows XP换成Linux。
|
||||
|
||||
地面/空中任务导向雷达（G/ATOR）系统已经研制了很多年。很可能在这项工程启动的时候Windows XP被认为是合理的选择。在研制的这段时间，事情发生了变化。微软已经撤销了对Windows XP的支持而且只有极少的几个组织会使用它。操作系统要么升级要么被换掉。在这种情况下，Linux成了合理的选择。特别是当替换的费用很可能远远少于更新的费用。
|
||||
|
||||
有个很有趣的地方值得注意一下。地面/空中任务导向雷达（G/ATOR）才刚刚送到美国海军陆战队，但是制造它的公司却还是选择了保留这个过时的操作系统。一定有人注意到的这样一个事实。这是一个糟糕的决定，并且指挥系统已经被告知了可能出现的问题了。
|
||||
|
||||
### G/ATOR雷达的软件将是基于Linux的 ###
|
||||
|
||||
Unix类系统，比如基于BSD或者基于Linux的操作系统，通常会出现在条件苛刻的领域，或者任何情况下都不能失败的的技术中。例如，这就是为什么大多数的服务器都运行着Linux。一个雷达系统配上一个几乎不可能崩溃的操作系统看起来非常相配。
|
||||
|
||||
“弗吉尼亚州Quantico海军基地海军陆战队系统司令部的官员，在周三宣布了一项与Northrop Grumman Corp. Electronic Systems在林西科姆高地的部分的总经理签订的价值1020万美元的修正合同。这个合同的修改将包括这样一项，把G/ATOR的控制电脑从微软的Windows XP操作系统换成与国防信息局（DISA）兼容的Linux操作系统。”
|
||||
|
||||
‘G/ATOR是一个远征三维中短距离多用途雷达系统。这个系统被设计成能够探测拥有低雷达截面的低可观测目标，比如火箭弹，火炮，迫击炮，巡航导弹以及无人机。”这些内容可以在[militaryaerospace.com][1]看到。
|
||||
|
||||
这项军用科技，即地面/空中任务导向雷达（G/ATOR），早在2005年就与Northrop Grumman签订了第一次合同。所以不难理解为什么美国海军可能想把这件事快点弄完。这次更换的时间限制还没有被提议。
