How is the AN/TPS-75 Aircraft Control and Warning System antenna aligned to the north?

The AN/TPS-75 Aircraft Control and Warning System antenna is aligned to the north electronically, which allows for precise and efficient operation. Electronic alignment utilizes sensors and calibration methods to detect the current orientation of the antenna and adjust it in real-time. This technique enhances the accuracy of target tracking and system performance, as it can account for any movements or shifts in the antenna's position.

Magnetic or mechanical methods could introduce variability or inaccuracies depending on environmental conditions or physical mechanics, which is why electronic alignment is preferred in modern radar systems. Though there may be some automatic processes in initialization, the core method of alignment specifically relies on electronic means to ensure optimal functionality.
