STA-901 GNSS Antenna — reliable satellite reception for weight‑sensitive and field applications Key benefits Multi-constellation reception: Supports BDS-3, GPS, and GLONASS to improve satellite availability and positioning continuity across different environments. Compact and lightweight: Designed for UAVs and handheld devices so you can add dependable GNSS performance without increasing payload or reducing portability. High gain with noise suppression: Built-in high-gain amplification and advanced noise reduction minimize signal loss and interference, preserving lock in electrically noisy or congested areas. Durable, all-weather construction: IP67 waterproof rating and ABS+PC radome protect the antenna from dust, rain, and rough handling for dependable outdoor operation. How this antenna solves common problems Reduces dropouts and short outages by combining multiple satellite constellations and high gain, delivering more consistent position fixes in urban canyons, under foliage, or near structures that block signals. Maintains signal quality in environments with electromagnetic interference thanks to active noise suppression, reducing the need for repeat passes or manual rework. Keeps system weight and form factor minimal so UAVs retain flight performance and handheld devices remain easy to carry and operate. With IP67 protection and a robust ABS+PC radome, the antenna withstands field conditions that would damage less rugged components. What makes the STA-901 stand out Purpose-built for mobile and airborne platforms where size and weight matter but GNSS reliability cannot be compromised. Balanced design that combines active signal amplification with interference mitigation and hardened materials for long-term field use. Broad compatibility with navigation applications and receivers that accept antennas supporting BDS-3, GPS, and GLONASS. Typical applications UAV mapping and aerial surveying: Mount on small to medium drones to improve satellite lock for photogrammetry, orthophoto capture, and LiDAR integration. Handheld field surveying and asset inspection: Use with portable GNSS receivers for faster fixes and fewer re-observations in urban or wooded areas. Outdoor navigation and remote operations: Reliable positioning for inspection teams, search and rescue, and mobile measurement systems operating in varied weather.
