2. Military-Grade Signal Processing
▸ GNSS LNA gain of 40±2dB, noise figure ≤1.5dB (25% lower than the previous generation GL208)
▸ LTE MIMO dual-antenna gain: 2.5dBi primary channel/2.0dBi secondary channel, enhancing transmission stability in weak network areas
3. Precision Measurement Guarantee
Phase center error of ±2mm, 360° horizontal coverage, and axial ratio ≤3dB, meeting millimeter-level surveying and mapping accuracy requirements
4. Ultra-Low Power Design
• GNSS power consumption ≤45mA @ 3-12V DC (25% lower than GL208)
• Dual-system coordinated power supply, suitable for solar-powered mobile devices
5. Industrial-grade protection
-40°C to +85°C wide operating temperature range
▸ Dedicated cables: RG316 shielded cable for GNSS, dual RG178 cables for LTE for interference resistance
▸ Supports custom interfaces such as Fakra
Application Scenarios
Smart infrastructure monitoring: Real-time monitoring of bridge/dam deformation (GNSS acquisition + LTE backhaul)
Unmanned mapping platform: Topographic mapping and data synchronization by drones/drone vessels
Precision agriculture: Real-time cloud upload of autonomous agricultural machinery operation trajectories
Emergency mapping: Rapid mapping of disaster sites and data exchange with command centers
Internet of Vehicles (IoV) terminal: High-precision positioning + integrated on-board 4G/5G communications
FAQ
Q: Does it support 5G NR frequency bands?
A: The LTE antenna covers 1710-2690MHz, including some 5G Sub-6G bands (n1/n3/n7, etc.), but requires terminal device support.
Q: How are the GNSS and LTE antennas powered?
A: They share a 3-12V wide-band input. The GNSS LNA requires a separate power supply, and the LTE antenna is powered by the terminal device.
Q: Is the Fakra interface compatible with standard devices?
A: The Fakra interface is standard (other types can be customized), directly compatible with vehicle-mounted communication hosts and industrial routers.
Q: Will the two antennas interfere with each other?
A: They use an isolated design with individually shielded cables (RG316 for GNSS and RG178 for LTE), with a V.S.W.R. ≤ 2.0 to ensure signal purity.
Q: Can it be used with the North American FirstNet emergency network?
A: It supports Band 14 (700MHz), covering the 698-960MHz frequency band, and meets FirstNet device requirements.
Q: Does the phase center parameter include the influence of the LTE antenna?
A: Factory calibration is only for the GNSS antenna (±2mm). LTE linearly polarized antennas do not affect positioning accuracy.
Q: Is the cable length customizable? A: Support RG316/RG178 cable length customization
