Product Introduction
1. Triple-band Full-Area Coverage
Simultaneously supports GPS L1/Glonass G1 (positioning) and LTE 698-2690MHz (communication), meeting both positioning and data transmission needs with a single device.
2. Military-Grade Signal Enhancement
A built-in 28dB high-gain LNA (±3dB fluctuation) and an ultra-low noise figure of ≤1.5dB improve positioning accuracy by 40% in weak signal scenarios.
3. Industrial Environment Hardiness
A ceramic antenna substrate and PC+ABS explosion-proof housing withstand extreme temperatures of -40°C to 85°C. 3M adhesive/screw mounting for vibration resistance.
4. Automotive-Grade Plug-and-Play
Comes standard with FAKRA automotive connectors and RG174 shielded cables, compatible with BMW, Volkswagen, and other vehicle systems, enabling quick deployment in 5 minutes.
5. Multi-Scenario Adaptability
RHCP circular polarization anti-interference design enables compatibility with complex environments such as drone image transmission, agricultural machinery navigation, fleet management, and marine positioning.
Application Scenarios
Smart Agriculture: Centimeter-level navigation for combine harvesters, with real-time crop data upload to the cloud platform.
Logistics Fleets: Temperature-controlled positioning of cold chain vehicles throughout their journey, with 4G LTE backhaul of location and cargo compartment status.
Industrial Drones: Power inspection drones maintain stable positioning in signal-blocked areas, with simultaneous HD imaging.
Marine Fisheries: Fishing vessels use satellite positioning in offshore waters without base stations, with automatic LTE switching nearshore.
Construction Machinery: High-precision attitude control for mining excavators in vibrating environments.
FAQ
Q: Does the GL312 support Galileo/Beidou systems?
A: Currently, only GPS L1 and Glonass G1 dual-satellite positioning are supported. Beidou requires a custom GL315 model (ODM service available).
Q: Will a 2dBi LTE antenna gain affect communication?
A: 2dBi is omnidirectional gain. Combined with a low VSWR of ≤3, it is optimized for urban multipath interference environments, with a measured coverage radius of ≥5km.
Q: What is the waterproof rating? A: The housing is IP67 rated (dustproof and immersion-resistant). The cable connector requires a waterproof rubber sleeve (optional accessory).
Q: Can a magnetic mount be used instead?
A: 3M VHB adhesive is included standard. The magnetic mount requires the optional GL312-MAG kit (load capacity ≥ 2kg).
Q: Are the FAKRA connector colors available?
A: The default color is blue (for GPS signals), but white, green, or purple can be customized to match automotive wiring harness standards.
Q: How is the power supply for an operating current ≤ 20mA?
A: It supports a wide voltage range of 3-5.5V and can be powered directly from a vehicle's 12V to 5V converter or a drone flight controller.
Q: Will the ceramic antenna break?
A: It uses an aerospace-grade aluminum nitride ceramic substrate, has passed a 1.5m drop test, and is resistant to aging for life.
