High performance roof-mount GNSS antenna

　　High-Performance Rooftop GNSS Antenna – Boost Positioning Accuracy from the Top

　　In the world of in-vehicle navigation and telematics, where every meter of accuracy and every second of signal reliability matter, GNSS antenna placement and performance can make the difference between success and failure. Our high-performance rooftop GNSS antenna is designed to transform your vehicle's roof into a strategic advantage, providing unobstructed satellite connectivity, industrial-grade durability, and precise positioning for fleets, autonomous vehicles, and dedicated transportation systems.

　　Why the Roof-Mount Design Superior Performance

　　1. Unobstructed Signal

　　Mounted on the roof, this antenna eliminates signal interference from metal chassis, tinted glass, and cargo, ensuring:

　　360° Satellite Visibility: Captures signals from low-altitude satellites (down to 5°), critical in urban canyons, dense forests, or mountainous terrain—areas where built-in or bumper-mounted antennas struggle.

　　Minimizes Multipath Error: Reduces signal reflections from nearby buildings, trees, or other vehicles by up to 80%, eliminating positioning drift in dynamic environments like city centers or highways.

　　Maintain a stable lock even while in motion: Maintain a stable connection during sharp turns, heavy acceleration, or off-road driving, ensuring a continuous data stream for real-time tracking and navigation.

　　2. Multi-constellation Precise Positioning: Global Coverage, Ubiquitous

　　Designed to leverage the power of the global satellite network, this antenna supports:

　　GPS (L1/L5), GLONASS (G1/G2), Galileo (E1/E5), BeiDou (B1/B2/B3), and QZSS, ensuring reliable positioning in areas where single-constellation coverage is difficult, such as remote deserts, coastal roads, or international borders.

　　Sub-meter Accuracy: When used with RTK/PPP correction services, it achieves horizontal accuracy of less than 1 meter, which is critical for fleet management (route optimization), lane keeping for autonomous vehicles, and emergency services (ambulance/fire truck dispatch).

　　Fast Time to Fix (TTFF): Locks onto satellites 30% faster than low-mounted antennas, reducing downtime during vehicle startup or after signal loss in tunnels.

　　3. Built for the Toughest Driving Environments

　　Vehicles face a variety of extreme conditions—this antenna is durable enough to handle them:

　　IP67 Water and Dust Resistance: Withstands heavy rain, snow, and road debris, making it an ideal choice for delivery trucks, construction vehicles, and off-road fleets.

　　Extreme Temperature Resistance: Operates flawlessly in temperatures from -40°C to +85°C (-40°F to 185°F), withstanding desert heat, extreme cold, and soaring under-hood temperatures.

　　Vibration and Shock Rated: Certified to withstand 20G vibration and 50G shock, ensuring durability even on rough terrain, unpaved roads, and unexpected bumps.

　　4. Seamless Integration with Vehicle Systems

　　Designed to work seamlessly with your telematics and navigation setup:

　　Universal Compatibility: Connects to fleet management systems (Geotab, Samsara), autonomous driving stacks, and GNSS receivers (u-blox, NovAtel) via a standard SMA/N connector.

　　Flexible Mounting Options: Choose between a magnetic (15 kg pull force, quick installation) or bolt-on (permanent, theft-resistant) mount for trucks, vans, buses, or specialty vehicles.

　　Low-Profile Aerodynamic Design: The sleek design (less than 50 mm in height) minimizes wind drag and fuel consumption, even at highway speeds.

　　Trusted Cross-Vehicle Applications

　　Commercial Fleets: Optimize routes, monitor driver behavior, and prevent theft with real-time, high-precision tracking.

　　Autonomous Vehicles: Provides reliable lane positioning and obstacle avoidance for self-driving cars, shuttles, and delivery robots.

　　Emergency Services: Ensures ambulances, police cars, and fire trucks reach their destinations with the fastest, most precise routes.

　　Construction and Mining: Tracks heavy machinery at remote work sites, ensuring efficient deployment and safety.

　　Recreational Vehicles: Provides consistent navigation for RVs and off-road vehicles in remote camping or adventure areas.

　　Globally Road Certified

　　CE, FCC, and E1 Marking Compliant: Meets stringent automotive and telecommunications standards for European, North American, and global markets.

　　ISO 9001 and IATF 16949 Certified Manufacturing: Stringent quality controls ensure every unit passes vibration, temperature, and signal performance tests.

　　Improve Vehicle Positioning Capabilities

　　Don't let substandard antenna placement limit your fleet's efficiency or safety. Our high-performance roof-mounted GNSS antennas transform your vehicle's roof into a precision hub, providing the reliability your operations demand.

　　Field-Tested Samples: Verify performance in your specific vehicle model and environment.

　　Customized Solutions: Request extended cable lengths (3 to 10 meters) or branded housings for fleet uniformity.
