I'm new to using STK and I'm trying to get a better understanding of the types of analysis that can be performed using this software. It seems like a lot. Specifically, I'm interested in knowing which types of analysis are considered the most useful or commonly used. Any insights or recommendations would be greatly appreciated! Thanks for the continued help.

Welcome to the STK community! STK is a powerful tool that offers a wide range of analysis capabilities. Here are some of the useful types of analysis you can perform in STK. STK is so broad, it was tough to come up with this short list so here are the first things I thought of!  

  1. Access Analysis: This type of analysis helps you determine the visibility or access between objects in your scenario, such as satellites, ground stations, and other assets. You can find the Access tools in the Analysis menu. This was the main reason why STK was built, for Line of Sight Analysis. It was the first and most used analysis in STK.  
  2. Coverage Analysis: This analysis allows you to evaluate how well a set of assets covers a specific area or volume. It's particularly useful for satellite constellation design and ground station coverage. Coverage tools are available from the Analysis menu and from STK Coverage object menus. This builds on the Access capabilities, which extends Access from 1 to 1, to 1 to a region or 1 to the entire globe. 
  3. Communications Analysis: This type of analysis is essential for evaluating the performance of communication links between assets. It helps you understand signal strength, interference, and other communication parameters. This can be found by running access from a Transmitter to a Receiver Object. 
  4. Geometric Analysis with Analysis Workbench: STK's Analysis Workbench capability includes tools for creating custom geometric, temporal and volumetric components and inserting them into your scenarios. This allows for more complex and tailored analyses to solve specific problems. These geometric capabilities include vectors, angles, coordinate systems, and planes among other things. Temporal is all things times, so any time instances, or time spans can be analyzed here. Volumetric is an advanced way of computing coverage that allows for 3D coverages. 
  5. Deck Access: This type of analysis is essential when have a single object and trying to access an entire database of analysis. For example, using a telescope to try to detect satellites, STK can run deck access to tell your telescope where to point. 


Each of these analysis types can be incredibly useful depending on your specific needs and the scenarios you're working with. If you need more detailed guidance, the STK Help documentation and tutorials are great resources to explore.

Great summary! I'd like to add a couple of tips: I run analysis in STK and these are the analysis capabilities I found most useful.

  1. EOIR: Can generate highly accurate simulated imagery for electro-optical and IR sensors. See more here.

  2. Conjunction Analysis: Scan the trajectory of all your assets against STK’s regularly updated 20,000+ object TLE database to assess conjunction risk. You can define the maximum allowable distance between your satellite and the other objects to account for positional uncertainty. See more here.

  3. Launch Window Analysis and LaserCAT: You can use the same conjunction analysis functionality for launch trajectories to determine safe launch windows into space, and to determine safe pointing for laser-based systems to ensure non-target objects do not pass within the range of the laser system. More info here and here.

  4. Chain Analysis: STK can chain line of sight access to determine the optimal route from one object to another through entire networks of objects. It’s a very powerful feature that was added recently to STK that’s worth checking out! See more info here.

  5. Scheduling: Designed for satellite operators, STK Scheduler can connect to your STK analysis, and add on contact scheduling and planning for operating and optimizing operations of multiple satellites. This is great for scheduling the optimal times for data downlink when large numbers of satellites are sharing a few ground stations, for planning data management for imaging satellites, and can grab necessary report from STK for availability windows, such as communications windows between the various satellites and ground stations. More info here. 

Happy analyzing!


Best,

Drew
