Analytical Graphics has decided to begin giving away its flagship product, the Satellite Tool Kit software. The software has thousands of features designed to help engineer, build and operate spacecraft, such as calculating how big solar panels should be by determining how long a satellite will be in shadows. The company has sold 1,500 copies of the software since 1992 at $10,000 a pop. But Analytical President and CEO Paul Graziani believes giving it away will greatly increase market penetration, thus spurring sales of "add-on" products that will more than offset the revenue loss. The software can be downloaded off the Internet at www.stk.com Getitgetitgetit! (I already have, needless to say. The Windows 95/NT version is 5.78 MB.) For those who don't know, a large part of STK is an orbital analysis suite.
