Book Description
Is your picosatellite ready for launch? Can it withstand rocket thrusts and the vacuum of space? This do-it-yourself guide helps you conduct a series of hands-on tests designed to check your satellite’s readiness. Learn precisely what the craft and its electronic components must endure if they’re to function properly in Low Earth Orbit. The perfect follow-up to DIY Satellite Platforms (our primer for designing and building a picosatellite), this book also provides an overview of what space is like and how orbits work, enabling you to set up the launch and orbit support you’ll need. Go deep into the numbers that describe conditions your satellite will face Learn how to mitigate the risks of radiation in the ionosphere Pick up enough formal systems engineering to understand what the tests are all about Build a thermal vacuum chamber for mimicking environment of space Simulate the rocket launch by building and running a vibration shake test Use a homebuilt centrifuge to conduct high G-force tests Get guidelines on scheduling tests and choosing an appropriate lab or clean room

Book Description
Want to build your own satellite and launch it into space? It’s easier than you may think. The first in a series of four books, this do-it-yourself guide shows you the essential steps needed to design a base picosatellite platform—complete with a solar-powered computer-controlled assembly—tough enough to withstand a rocket launch and survive in orbit for three months. Whether you want to conduct scientific experiments, run engineering tests, or present an orbital art project, you’ll select basic components such as an antenna, radio transmitter, solar cells, battery, power bus, processor, sensors, and an extremely small picosatellite chassis. This entertaining series takes you through the entire process—from planning to launch. Prototype and fabricate printed circuit boards to handle your payload Choose a prefab satellite kit, complete with solar cells, power system, and on-board computer Calculate your power budget—how much you need vs. what the solar cells collect Select between the Arduino or BasicX-24 onboard processors, and determine how to use the radio transmitter and sensors Learn your launch options, including the providers and cost required Use milestones to keep your project schedule in motion

Book Description
La 4e de couverture indique : "Whether your picosatellite is watching the Earth or gazing at the stars, you need to know what you're sensing. This do-it-yourself guide explains what you can measure---and the constraints on those measurements---when you're orbiting the Earth. Learn exactly what physical quantities you can measure, and how to plan your sensor loadout. The perfect follow-up to DIY Satellite Platforms (our primer for designing and building a picosatellite), this book takes you beyond just flying a camera in space and shows you what data you can gather and play with using your own personal satellite. Learn about all the sensors you can select for your mission; get acquainted with key electronic communications protocols; I2C, TTL, SPI, analog, and digital; find out how much more your instruments can "see" when they're above the atmosphere; Understand how to calibrate sensors and how to pick the signal out of the noise; determine the optimal data acquisition rate for your available bandwith; [and] look at off-the-shelf sensor hardware and CPU choices (such as Arduino)"

Book Description
Radio spectrum for commanding and recording from our satellites is a shared resource with subtle hurdles. We walk the path originally paved by AMSATs to discuss the steps and licensing needed to set up and operate both a command uplink and a data download station and network. Find out how playing nicely with others maximizes your ability to get your data down.
Tcl/Tk in a Nutshell
Author: Paul RainesPublisher: "O'Reilly Media, Inc."
ISBN: 0596555792
Category : Computers
Languages : en
Pages : 458
Book Description
The Tcl language and Tk graphical toolkit are simple and powerful building blocks for custom applications. The Tcl/Tk combination is increasingly popular because it lets you produce sophisticated graphical interfaces with a few easy commands, develop and change scripts quickly, and conveniently tie together existing utilities or programming libraries.One of the attractive features of Tcl/Tk is the wide variety of commands, many offering a wealth of options. Most of the things you'd like to do have been anticipated by the language's creator, John Ousterhout, or one of the developers of Tcl/Tk's many powerful extensions. Thus, you'll find that a command or option probably exists to provide just what you need.And that's why it's valuable to have a quick reference that briefly describes every command and option in the core Tcl/Tk distribution as well as the most popular extensions. Keep this book on your desk as you write scripts, and you'll be able to find almost instantly the particular option you need.Most chapters consist of alphabetical listings. Since Tk and mega-widget packages break down commands by widget, the chapters on these topics are organized by widget along with a section of core commands where appropriate. Contents include: Core Tcl and Tk commands and Tk widgets C interface (prototypes) Expect [incr Tcl] and [incr Tk] Tix TclX BLT Oratcl, SybTcl, and Tclodbc
