What specific info does the INFS provide to the ECS?

The INFS (Inertial Navigation Flight Sensor) provides essential information to the ECS (Engagement Control Station) about the orientation and movement of the missile system. Specifically, azimuth, roll, and cross roll are critical for accurately determining the missile's position in three-dimensional space and ensuring it is aimed correctly for optimal targeting. This data allows the ECS to make real-time adjustments to the missile’s trajectory based on its current flight dynamics, ensuring that it can maintain the correct path and achieve its intended impact point. Understanding this information is crucial for effective missile guidance and control during operations.
