Defined Radio (RTL SDR), combined with an easy Homemade Quadrifilar Helix QFH antenna, . The software component of the station is built with GNU Radio, an open source tool with a rich set of signal processing features, Gpredict, a satellites tracker and Wxtoimg, a free weather satellite decoding program which can decode the APT signal Keywords— RTL-SDR, GNU Radio Companion, Ground Station, NOAA. I. INTRODUCTION The techniques of weather satellites images reception has immediately advanced in the

management and networking tasks. Lonix OS drivers are either directly integrated with the kernel or come in as additional modules created while the system is awake. Independent developments with kernel interface improve the functionality and performance. GNU user land association with Linux based systems provides majority executions in the C library, a command-line interface (CLI) shell and the most common tools of UNIX to carry out performance execution. A GUI is created on each implementation of the X

The Linux was originally founded by Linus Torvalds. In 1991, he was a second year computer science student in Finland. He sought after an operating system that was similar to the UNIX system, but both UNIX and the hardware it ran on were excessively expensive. A UNIX version called Minix was available for free, but it did not reasonably meet his needs as it was simply an operating system for students, designed primarily as a teaching tool rather than an industry strength operating system. As a result

individuals do today and there were many reasons for this. During the French Revolution there was a large amount of taxation for certain class groups, “While average tax rates were higher in Britain, the burden on the common people was greater in France” (GNU, 2008, pg. 2). Due to these large taxations on the peasants and lower class and not on the clergy and nobles it caused excessive conflict between the classes. Not only was taxation a cause of conflict between classes but so was the corrupt monarchy

You can’t know where you’re going unless you know where you been, this saying rings true when thinking of Lunix. In order to know the start of Lunix one would have to travel back in time quite a bit. In this paper, I will research the start of Linux, the growth, and the future. When thinking of computers imagine they are as big as the tallest building or stadium. While the size of those computers posed problems, there was the one thing that made them worse: every computer had a different operating

William Wang Christian 5th 7 April 2015 Capstone project Have you wonder where the power of technology and computers and all of the applications came from? Well there are a lot of computer applications like local security applications, protocols, well I am going to explain some security applications to you. There are many kinds of different security applications. I am going to explain two of different applications Linux and security policy settings. Now what are security policies? Security policy

The Different Flavors of Linux CIS 155: Operating Systems 6/7/2012 Depending on your personal preference and need, there are a variety of operating systems available to users today. Whether it’s MAC OS, UNIX, Windows, etc they each have their own aspects and appeal that draw users in. The spotlight however, for the duration of this paper will be placed on a derivative of the UNIX family of operating system, Linux. The topics covered will include the history to include a handful of versions

the work being undertaken by the software engineer. The software must contain a custom driver to unpack the VITA-49 packet outlined before. This driver will be written to work with a Ubuntu Linux distribution. The unpacked data will then be handed to GNU Radio Companion and the signal processed. The FFT, dynamic peak algorithm, spectrum display and list of signals are default tools that can be downloaded from the file repository [16]. The module will require a custom module called an “out of the tree

Over the weekend nights, Stoll found two huge breakthroughs when he analyzed the intruder’s activities recorded in the eighty feet of single-spaced computer paper by. These breakthroughs are not just of interest, but of great importance. When the hacker dialed in that weekend, Stoll located the phone line, which was coming from the Tymnet routing service instead of through dialed-in modem. Tymnet is a series of fiber-optic cables that interconnected the computers around the world. This indicates

“I'm doing a (free) operating system (just a hobby, won't be big and professional like gnu) for 386 (486) AT clones. This has been brewing since april, and is starting to get ready. I'd like any feedback on
