Product Introduction
Dual-Band GPS/GNSS Support
Covers 1575.42MHz (GPS L1) and 1176.45MHz (L5) frequencies, ensuring compatibility with modern high-precision navigation systems.
High-Performance Ceramic Design
Ceramic material provides low signal loss and stable RF performance, ideal for demanding environments.
Ultra-Compact & Lightweight
Available in 18x18x2mm and 25x25x2mm sizes, perfect for space-constrained devices like drones, wearables, and IoT trackers.
Robust Temperature Stability
Frequency temperature coefficient ≤20ppm/°C, maintaining accuracy across -40°C to +85°C operating ranges.
Optimized Signal Integrity
Right-Hand Circular Polarization (RHCP) and 50Ω impedance minimize multipath interference for reliable satellite signal reception.
Autonomous Drones/UAVs: Ensures stable GPS signals for precision navigation and geofencing.
Smart Agriculture: Integrate into soil sensors or tractors for field mapping and automated guidance.
Fleet Management: Embed in vehicle trackers for real-time logistics monitoring.
Wearable Tech: Compact size suits fitness trackers or emergency locators requiring GPS.
Industrial IoT: Deploy in harsh environments for asset tracking and machinery positioning.
Q:Is this antenna compatible with Galileo/GLONASS systems?
A:Yes. The dual-band design supports GPS L1/L5, Galileo, and other GNSS constellations.
Q:Can it operate in extreme temperatures?
A:Absolutely. It functions reliably in -40°C to +85°C, ideal for outdoor/industrial applications.
Q:Does it require an external amplifier?
A:No. The ceramic design ensures low signal loss, but pairing with an LNA can further enhance performance.
Q:What mounting options are available?
A:It supports standard PCB surface mounting, optimized for automated assembly processes.
Q:Is it ROHS compliant?
A:Contact Global East Asia Technology for certification details.
