01
Ultra-Long-Range Precision Laser Ranging
Equipped with a 1535±5 nm eye-safe laser, the JV-LRFM series delivers fast and precise ranging with ±1 m accuracy, 1–10 Hz measurement frequency and a ≥98% ranging success rate. The JV-LRFM4 supports large-target ranging ≥5.6 km, while the JV-LRFM8 extends the maximum range to ≥10 km for demanding long-distance observation.
02
Day & Night Observation with Multi-Sensor Positioning
Featuring a built-in 1920×1080 low-light camera and 3.3×~80× optical zoom, the system supports clear target observation in both daytime and low-light conditions. Integrated BeiDou/GPS/GLONASS positioning, automatic magnetic-declination correction and 0.5° RMS azimuth accuracy enable reliable ranging, positioning and directional measurement in complex field environments.
