Anti-Jamming Multi-GNSS High Precision Antenna for Autonomous Driving

　　Why Choose Our Anti-Jamming Multi-GNSS Antenna for Autonomous Driving?

　　Tailored for all levels of autonomous driving (L3-L5)—including urban Robotaxis, highway freight autonomous trucks, mining unmanned vehicles, and closed-scenario autonomous shuttles—our anti-jamming multi-GNSS high precision antenna delivers uninterrupted, centimeter-level positioning even in harsh electromagnetic environments, serving as the "core positioning anchor" for safe, reliable autonomous navigation.

　　1. Multi-Layer Anti-Jamming Technology: Conquer Complex Urban/Highway Interference

　　Wideband Anti-Jamming Capability: Equipped with adaptive beamforming + 12-channel interference suppression (supports 200MHz-6GHz anti-jamming bandwidth)—effectively resists electromagnetic interference from urban infrastructure (e.g., 5G base stations, power lines), vehicle-mounted electronics (e.g., motors, radar systems), and intentional jamming signals, ensuring positioning stability in downtown areas with dense electromagnetic sources.

　　Anti-Multipath Optimization: Integrated high-performance choke ring + low-noise amplifier (LNA, noise figure ≤0.8dB)—eliminates signal distortion caused by multi-path reflection (e.g., high-rise building canyons, tunnel entrances/exits, highway overpasses), a key pain point for urban autonomous driving.

　　GNSS Redundancy Shield: Simultaneously tracks 6 global satellite systems (GPS L1/L2/L5, BDS B1/B2/B3, GLONASS G1/G2, Galileo E1/E5a/E5b, QZSS L1/L2/L5, NavIC L5)—avoids positioning failure due to single-system interference (e.g., GPS signal blockage), achieving 99.999% positioning availability (meets ISO 21448 "Safety of the Intended Functionality" for autonomous driving).

　　2. Ultra-High Precision & Low Latency: Meet Autonomous Driving Dynamics

　　Dynamic Positioning Accuracy: ≤3cm horizontal precision (dynamic RTK mode); ≤5cm vertical precision—fully complies with SAE J3164 (Positioning Accuracy Requirements for Autonomous Vehicles), supporting precise path planning for L4 Robotaxis (e.g., lane-level switching, narrow road passing) and high-speed autonomous trucks (e.g., 90km/h adaptive cruise positioning).

　　Low Latency Response: ≤10ms positioning data update rate—matches the real-time decision-making needs of autonomous driving systems (e.g., emergency braking, obstacle avoidance), avoiding delays caused by signal processing.

　　Static Drift Suppression: ≤0.3cm/hour during low-speed urban driving—ensures consistent positioning accuracy when stopping at traffic lights or navigating congested roads, preventing "positioning drift" that leads to lane departure.

　　3. Automotive-Grade Reliability: 24/7 All-Scenario Operation

　　Automotive-Grade Environmental Adaptation: Passes IP6K9K (high-pressure water washing + dustproof) + -40℃ to 95℃ (-40℉ to 203℉) wide-temperature testing—resists vehicle high-pressure cleaning, engine compartment heat radiation, and extreme weather (snow, heavy rain) for year-round stable operation.

　　Vibration & Shock Resistance: Complies with ISO 16750-3 (mechanical load for automotive electronics)—withstands 2000Hz vibration (matching highway driving vibration frequency) and 50G impact (emergency braking/collision prevention), avoiding antenna damage from vehicle dynamics.

　　EMC Compliance: Meets CISPR 25 Class 5 (electromagnetic compatibility for automotive components)—no electromagnetic radiation interference with on-board sensors (lidar, millimeter-wave radar, cameras), ensuring multi-sensor fusion stability for autonomous driving.

　　4. Seamless Integration with Autonomous Driving Systems

　　Standardized Automotive Mounting: Supports ISO 15118-compliant roof/windshield mounting (compatible with Tier1 standard brackets)—no vehicle body modification, enabling integration into production lines (e.g., Tesla, Waymo, Cruise vehicle platforms) in 8 minutes.

　　Multi-Sensor Synergy: Compatible with mainstream autonomous driving domain controllers (e.g., NVIDIA Orin, Mobileye EyeQ6) and V2X (Vehicle-to-Everything) systems—realizes "GNSS + V2X + lidar" multi-source positioning fusion, enhancing positioning reliability in signal-degraded scenarios (e.g., long tunnels).

　　Automotive Power Compatibility: Works with 12V/24V vehicle power systems (working current ≤35mA)—avoids overloading the vehicle electrical network, suitable for both passenger cars (12V) and heavy-duty trucks (24V).
