Applying Analysis Workbench to your Interplanetary Missions

By: Lauren McManus

Analysis Workbench just might be one of the most powerful tools in STK. It allows you to access STK’s physics-based engine in order to manipulate and create new calculations and geometry. Analysis Workbench has four calculation types: Vector Geometry, Time, Calculation, and Spatial Analysis.

Analysis Workbench is useful for any STK scenario, but its capabilities can be particularly powerful for interplanetary missions. All STK scenarios have a reference central body and there are some calculations that only work properly for the reference central body. As long at the scenario all takes place at that body, everything works perfectly, but once you leave, things work a little differently. But have no fear! You can create custom components in Analysis Workbench to perform these same calculations at any planet, moon, or asteroid your heart desires! Here are just a couple of examples:

  1. Use the vector geometry and calculation tools in Analysis Workbench to calculate the subsolar or sub-observer points. The subsolar point is the point on a planet where the sun is perceived to be directly overhead. Likewise, the sub-observer point is where a satellite is perceived to be directly overhead. Check out the FAQ on this topic for detailed steps.
  2. Use the vector geometry tool in Analysis Workbench to set Nadir-like attitude profiles for satellites at various central bodies. There is also an FAQ for how to implement this!
