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

Software has become an integral part of our society. The economic success of our country depends on the success of the software industry. ``Open source ' ' software, software which users are allowed to modify and redistribute, is a very important part of the software industry Copyright and patent laws are inappropriate for computer software, their imposition slows down software development and reduces competition. Computer software has become more and more important. Software has played an important

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

powerful, free and inexpensive to own based on UNIX [1]. It is a POSIX-compliant with versions available to install in cell phones, supercomputers and most computing systems [1]. Linux is an open source program as its source code is available to the general public for use and the right to modify from its original design without any charges [1]. New code will be added to the next version made available with Linux if it is accepted as a universal improvement [1]. The code will continue to exist and developed

Ewing wore that was given to him by his grandfather, while attending Carnegie Mellon University. The distribution was then bought in 1995 by Bob Young who had incorporated the ACC Corporation in 1993. Red Hat Software was then born and then went public on Wall Street on August 11, 1999. Only a few months after that with the new CEO, Matthew Szulik, Red Hat began acquiring other companies, such

In this report, I will be discussing operating systems, management of information, security and application software within a school environment and personal use. The context of this report will be inclusive of my internal assessments of which I have completed at school, and at home. Operating software (OS) An operating system has the ability to manage both the hardware and software of a computer or device. It is the most important part of a computer and controls every action and task which is

the FOSS model as a viable business model. (Upfold, Peter 2006) My personal opinion is that this was an attack on the open source community. Microsoft hasn’t actually changed its tune; it’s still actively attacking free software and trying to abolish GNU/Linux while promoting Windows and other proprietary software as though they are complementary to free software, which they are not. It’s PR nonsense and Microsoft is good at PR. Since then, Novell was sold in 2010 to Attachmate Corp. and a concurrent

Machine Learning. This Chapter presents a general overview of R and Python, their characteristics and usage for machine learning. Lastly, a comparison matrix of R and Python for ML is provided at the end of this chapter. About R R stands for both the statistical programming language and the software environment. It is one of the most popular statistical environment for machine learning and general data analysis. R is licensed under the GNU General Public License, with copyright held by The R Foundation
