h1. Link simulation using LabVIEW tool

LabVIEW (Laboratory Virtual Instrument Engineering Workbench) is a system-design platform and development environment for a visual programming language from National Instruments.

The graphical language is named "G". Originally released for the Apple Macintosh in 1986, LabVIEW is commonly used for data acquisition, instrument control, and industrial automation on a variety of platforms including Microsoft Windows, various versions of UNIX, Linux, and OSX. The latest version of LabVIEW is LabVIEW 2015, released in August 2015.

The net result of using a tool such as LabVIEW is that higher quality projects can be completed in less time with fewer people involved.

So productivity is the key benefit, but that is a broad and general statement. To understand what this really means, consider the reasons that have attracted engineers and scientists to the product since 1986. At the end of the day, engineers and scientists have a job to do, they have to get something done, they have to show the results of what they did, and they need tools that help them do that. Across different industries, the tools and components they need to succeed vary widely, and it can be a daunting challenge to find and use all these disparate items together. LabVIEW is unique because it makes this wide variety of tools available in a single environment, ensuring that compatibility is as simple as drawing wires between functions.

LabVIEW itself is a software development environment that contains numerous components, several of which are required for any type of test, measurement, or control application.

In this project, we mainly use the G programming component to simulate the Downlink performance of Voyager 1 (from spacecraft to the earth station). And to assess the solution performance that we propose in order to conquer more and more longer communication distance.
