New Feature: Coverage
(Massively Parallel Access Calculations)

One of the great features coming soon in AGI Components is Coverage analysis.  I am going to talk a bit here about what Coverage is, what you can do with it, and what sort of features will be coming in the components.  Coverage is a term used by James Wertz and Wiley Larson in Space Mission Analysis and Design (or SMAD for short).  Here is what SMAD has to say:

"Earth coverage refers to the part of the Earth that a spacecraft instrument or antenna can see at one instant or over an extended period.  The coverage available for a particular location or region is frequently a key element in mission design." p 163

So essentially, Coverage is a means by which we can take a set of resources or "assets" and analyze their ability to observe (and possibly interact) with a set of locations (or objects) on the ground.  Numerically, this usually entails representing a given area on the surface of the Earth (or other CentralBody) as a set of grid points.  What this means is hundreds if not thousands of access calculations happening in parallel between each grid point and any number of time-dynamic 'assets'.  The goal is to allow the user to conveniently assemble the problem and run the analysis without having to manually configure each access calculation.  SMAD goes on to talk about the use of "Figures of Merit" (p173) which represent scalar fitness values based on statistical analysis of the results of the coverage computation.  This allows the user to effectively analyze and design complex missions based on various fitness criteria.

Have your analysis and eat your visualization, too

The various libraries that compose AGI Components are great for analyzing the time-dynamic relationships in all sorts of aerospace and defense scenarios, but that's only half the story. Our company is called Analytical Graphics for a reason. We're all about high-precision analysis, but we're also all about letting you see your analysis results in an intuitive and precise manner using 3D graphics.

Sure, AGI Components works great for generating analysis results which can then be pumped out to any number of virtual globes like Google Earth, Microsoft Virtual Earth, or NASA World Wind. But we happen to think that our own virtual globe, available in STK and and 4DX, blows all of these away. This is particularly the case when you need to visualize things that.. well.. move.

On that note, I'm very excited to pass along word that AGI's Point Break team has just completed an Alpha release of the visualization component of the AGI Components family.
