The USCHO Fan Forum has migrated to a new plaform, xenForo. Most of the function of the forum should work in familiar ways.
Please note that you can switch between light and dark modes by clicking on the gear icon in the upper right of the main menu bar.
We are hoping that this new platform will prove to be faster and more reliable. Please feel free to explore its features.

"The missile knows where it is at all times. It knows this because it knows where it isn't. By subtracting where it is from where it isn't, or where it isn't from where it is (whichever is greater), it obtains a difference, or deviation.
The guidance subsystem uses deviations to generate corrective commands to drive the missile from a position where it is to a position where it isn't, and arriving at a position where it wasn't, it now is."
