GPS Active Antenna1575.42 MHz 28dBi
Product Introduction
The BGS‑MM1575‑463515B‑5M is a professional‑grade active antenna module designed for high‑precision positioning applications. Optimized for the 1575.42 MHz (L1 band), it supports concurrent reception of GPS, BeiDou, GLONASS, and Galileo signals. Delivering centimetre‑level accuracy in challenging environments such as urban canyons, the module features a compact form factor and a standard 5‑meter cable length, making it easy to integrate into various outdoor mobile devices and fixed stations.
Typical Application Areas
| Field | Specific Use Cases |
|---|---|
| Precision Agriculture | Autonomous tractors, variable‑rate fertilization systems, field mapping – requiring sub‑metre / centimetre accuracy. |
| Intelligent Transportation | Bus / logistics fleet management, lane‑level navigation, high‑precision positioning for autonomous driving test vehicles. |
| Surveying & Mapping | GIS data collection, engineering stakeout, bridge / slope monitoring – static or RTK operation. |
| UAVs & Robotics | Agricultural drones, inspection robots, automatic mowers – resistant to vibration with fast re‑acquisition. |
| Marine & Port | Ship autopilot, container positioning in ports, buoy monitoring – salt‑mist resistant and anti‑corrosion. |
| Security & Timing | Power / communication base station timing, police positioning devices, personnel trackers – low latency and high reliability. |
