What component is used to find north manually on the sentinel radar?

The Boresight telescope assembly is the correct component used to find north manually on the Sentinel radar. This device allows operators to visually align the radar with true north, ensuring that the radar's operational parameters and data accurately represent the surrounding environment. The functionality of the assembly involves aiming the telescope at a known landmark or celestial body at known coordinates, providing a reliable reference point to calibrate the radar system.

Understanding the role of the Boresight telescope assembly enhances the operator's capability to effectively utilize the radar system for target detection and tracking. This manual alignment process is essential in maintaining the system's accuracy, particularly in situations where electronic compass readings might be unreliable due to interference or environmental conditions.
