The SV-2-80D Dual-Optical Platform Image Seeker is a two-axis stabilized seeker that identifies and tracks targets in visible and infrared bands and outputs the target deviation angle from the optical axis to guide the carrier precisely. With a 3840×2160 CMOS daylight camera (26° × 15° FOV) and an uncooled 640×512 long-wave infrared camera (23° × 18° FOV), the seeker provides autonomous recognition at 1.2 km and human-in-the-loop lock-on tracking at 2 km for a 5 m × 5 m target on visible light, and 750 m / 1.2 km respectively on infrared. The stabilized frame covers pitch from −80° to +25° and yaw from −60° to +60° with isolation of 2% or better and frame angle accuracy of 0.3°. Line-of-sight angles are output at 50 Hz with tracking angular rates of ±20°/s and misalignment of 0.3° or less. Weighing ≤400 g in a Φ80 × 105 mm body, the SV-2-80D suits medium- and low-speed UAVs up to 80 m/s, drawing ≤20 W from 18–32 V and operating from −40 °C to +60 °C.
