The SV-1-80 Dual-Optical Strapdown Image Seeker uses high-definition visible-light and infrared detectors to image the brightness and thermal signatures of targets, identify and track them, and output the deviation angle of the target from the optical axis so the carrier can be guided precisely onto it. Because it is strapdown — fixed to the airframe without a stabilization gimbal — the seeker weighs only 150 g in a Φ80 × 80 mm housing and withstands 300 g longitudinal overload, ideal for small guided munitions and foldable fixed-wing or multi-rotor carriers. The 4K CMOS channel (3840×2160, 60° × 36° FOV) tracks typical targets reliably beyond 1.5 km, while the uncooled 640×512 infrared channel (32° × 24° FOV) maintains reliable tracking beyond 1 km for day/night operation. Line-of-sight angles are output at 50 Hz with error of 0.2° or better across the ±15° field, and disturbance resistance is 60°/s or more. Power draw averages ≤20 W from an 18–32 V supply, with RS422/RS232 and 100M Ethernet interfaces and −40 °C to +60 °C operation.
