If – Else Vector

There are a number of features in STK that don’t quite get the love they deserve and the Scheduled Vector is definitely one of them. Do you ever need a vector to point in different directions depending on some condition? For example:

• Point your sensor in a certain direction except when the Sun comes within x degree of the sensor boresight.
• Point your satellite solar panels at the Sun except when in umbra, then point them parallel to the velocity vector to reduce drag.
• …

Back in the dark ages (before STK11), this required you to write a vector plugin, but can now easily be built in the GUI. Below is an example of a sensor on an aircraft that points towards nadir and can gimbal up to 25 degrees. So when the bank angle is < 25 degrees, the sensor points towards nadir. When the bank angle gets > 25 degrees, the sensor points at 25 degrees towards nadir.
