Product Description
Product Description
The GL-385 is a high-performance multi-GNSS antenna engineered for professional applications requiring extensive signal compatibility. It supports a wide range of frequencies from BDS, GPS, GLONASS, and Galileo, including advanced E6 and L-Band signals. With an LNA gain of 36±2dB, excellent phase center stability (±5mm), and a robust N-F connector, it ensures reliable, high-accuracy positioning. Designed for durability, it operates from 3.0–12V DC, withstands temperatures from -40℃ to +80℃, and is built for demanding environments. Ideal for reference stations, precision surveying, and scientific monitoring where signal integrity and multi-frequency performance are paramount.

FAQ
Q1: What level of positioning accuracy can this antenna support?
A: This antenna is designed to support centimeter to millimeter-level accuracy when used with a compatible GNSS receiver in RTK (Real-Time Kinematic) or PPK (Post-Processed Kinematic) modes. Its stable phase center (±5mm) and low axial ratio ensure reliable signal quality for high-precision applications.
Q2: Is the antenna compatible with my existing GNSS receiver?
Q2: Is the antenna compatible with my existing GNSS receiver?
A: Yes, it supports all major GNSS systems (GPS, GLONASS, Galileo, BDS) across multiple frequencies. It uses a standard SMA connector and operates on 3–12V DC, making it compatible with most industrial and surveying-grade receivers.
Q3: Can it be used in harsh environmental conditions?
A: Absolutely. The antenna is built to operate in temperatures from -40℃ to +85℃ and withstand up to 95% non-condensing humidity, making it suitable for outdoor, marine, and industrial environments.
Q4: How should the antenna be mounted for optimal performance?
A: For best results, mount the antenna on a stable, metallic ground plane with a clear view of the sky. Ensure the polarization (RHCP) is oriented upward, and avoid obstructions near the antenna's horizon.
Q5: Is the antenna suitable for moving platforms like drones or vehicles?
A: Yes. Its lightweight design (≤150g), low power consumption, and robust performance across dynamics make it ideal for UAVs, autonomous vehicles, agricultural machinery, and marine navigation systems.
