Target Tracking Gimbal - Active Control
Many ISR, military, and law enforcement applications require pointing a sensing payload at a moving target. Aircraft can be fitted with a sophisticated sensor suite consisting of Electro-Optical/Infra Red (EO/IR) instruments in combination with a laser rangefinder (LRF), or other remote sensing systems and combinations on a two-axis gimbal to enable precise target tracking. This note provides a detailed analysis for choosing the right GNSS/INS system for such applications, alongside other integration considerations that will determine total system performance. The error budget is derived and an example provided to demonstrate the impact of various design choices.
