Details
Designed for single-frequency, multi-constellation reception (GPS L1, GLONASS L1, BDS B1, GALILEO E1) in positioning and measurement projects.
Support options include sourcing, customization, and technical assistance for integrators and project deployments.
Core electrical and mechanical parameters are summarized for quick integration checks, including LNA gain, voltage range, and IP67 waterproofing.
Multi-constellation coverage and stable reception help address common issues like poor positioning accuracy and weak signal environments.
Multi-system compatibility supports wider satellite availability, paired with 360° horizontal coverage for outdoor installations.
High LNA gain (38±2 dB) and a 2.8–5 V supply range suit many GNSS receiver and controller setups.
A compact low-profile housing measures Φ160 × 66.5 mm for easy mounting on vehicles, tripods, and equipment frames.
An IP67-rated housing with UV-resistant material is built for long-term outdoor exposure.
Mounting hardware options include a 5/8"-11 UNC deep 20 thread plus eight screw holes, with a TNC-K interface for the feed cable.
Suitable for a range of positioning workflows, from field RTK setups to fixed outdoor measurement points.
Common uses include precision agriculture, geodetic and channel surveying, marine measurement, logistics tracking, and driving training.
Choose antenna-only or a bundle with matching cable/connector options based on your receiver interface and cable-length needs.
