Full-Band Survey GNSS Antenna for GPS, BDS, GLONASS & Galileo
A high-precision survey GNSS antenna supporting all frequency points of GPS, BDS, GLONASS and Galileo, built for BeiDou-3 and multi-system compatibility in professional surveying equipment.
- High gain and wide beam: strong low-elevation reception and stable satellite tracking even in heavily obstructed environments
- High out-of-band rejection against interference from communication base stations and other signals
- IP67 waterproof, dustproof and UV-resistant housing for long-term outdoor use
Product Overview
This full-band survey GNSS antenna is engineered for centimeter-level positioning work where signal quality decides accuracy. It covers GPS L1/L2/L5, BDS B1/B2/B3, GLONASS L1/L2/L3, Galileo E1/E5a/E5b/E6 and L-Band, so your GNSS receiver can track every available constellation and frequency.
With a maximum gain of 5.5 dBi, a phase center error of only ±2 mm and a built-in low noise amplifier, it is a dependable choice for surveying and mapping, marine surveying, geological monitoring, bridge deformation monitoring, automated ports, UAVs, UGVs and other demanding applications.
Key Features of the Survey GNSS Antenna
High Gain, Wide Beam
Excellent reception of low-elevation satellite signals, with normal tracking maintained in severely obstructed environments such as urban canyons, forests and open-pit sites.
Advanced Antenna Design
Innovative coupled feed with broadband phase balancing technology, plus a low-loss composite polymer dielectric substrate, delivers consistent phase performance across the band.
Multi-System, Multi-Frequency
Wide operating bandwidth supports multi-constellation, multi-frequency operation, including the globally deployed BDS B3, L5 and L-Band frequency points, which greatly improves system stability.
High Out-of-Band Rejection
Effectively suppresses interference from communication base stations and other RF sources, preventing instability in your GNSS receiver.
Low-Noise Amplification
Built-in LNA with 38±2 dB (L1) and 40±2 dB (L2) gain and a noise figure of 1.8 dB or less preserves weak-signal sensitivity.
Rugged IP67 Housing
Compact, reliable structure that is waterproof, dustproof and UV-resistant, rated from -40°C to +85°C for long-term outdoor deployment.
Built for Reliable Surveying Equipment
The Φ150 × 61 mm body weighs 400 g or less and mounts directly on a standard 5/8"×11 imperial thread, so it fits survey poles, tripods, base stations and CORS installations without adapters. A TNC-K connector provides a secure, low-loss RF connection.
Right-hand circular polarization with an axial ratio of 3 dB or less and a 0°–360° horizontal coverage angle ensure uniform reception from every direction.
