Description
Product Overview EV288 UAV Anti-Jamming GNSS Antenna — Full-Frequency Multi-System GPS / BDS / GLONASS / Galileo / L-Band
Full-Frequency Multi-Band GNSS Antenna | GPS L1/L2/L5 · BDS B1/B2/B3 · GLONASS L1/L2/L3 · Galileo E1/E5a/E5b/E6 · L-Band | IP67 | GB/T Vibration & Salt Spray Certified | Precision Agriculture · Autonomous Vehicles · UAV
The EV288 Multi-Frequency Band GNSS Antenna is a full-frequency, field-certified, multi-system GNSS antenna engineered for precision agricultural automation and autonomous ground vehicle applications where GNSS signal reliability and physical durability are equally critical to mission success. Supporting GPS L1/L2/L5, BeiDou B1/B2/B3, GLONASS L1/L2/L3 — including the third GLONASS frequency L3 for improved ionospheric modeling — Galileo E1/E5a/E5b/E6, and L-Band, the EV288 provides complete signal coverage across all current and next-generation GNSS constellations in a single antenna optimized for agricultural and industrial environments.
The EV288 is unique among UAV and vehicle GNSS antennas in its comprehensive GB/T national standard field certification program. Vibration certification to GB/T 2423.100 validates continuous operation through 1-30Hz agricultural machinery ground vibration at 0.75mm amplitude for 50 minutes and 30-55Hz engine/drivetrain vibration at 0.25mm amplitude for 25 minutes across all three axes — directly simulating the vibration spectrum of operating tractors, harvesters, and autonomous vehicles. Impact certification to GB/T 2423.5 validates survival through 50m/s² acceleration at 18ms duration for 18 separate impacts. Salt spray certification to GB/T 2423.18 validates 72-hour exposure to 5% salt solution — critical for coastal agricultural operations, marine-adjacent logistics, and port autonomous vehicle deployments. Three-meter free-fall drop resistance provides additional confidence for field handling and transport.
Galileo E5a full support — in addition to E5b and E6 — gives the EV288 complete Galileo five-frequency capability including the AltBOC E5 wideband signal used for the highest-accuracy Galileo positioning. Combined with L-Band support for commercial PPP correction services and GPS L5 for the latest dual-frequency ionospheric-free combination, the EV288’s frequency coverage represents the most complete GNSS signal support available in its antenna class — future-proofing agricultural machinery and autonomous vehicle GNSS systems against evolving constellation signal additions.
At 107 × 43mm with standard 5/8″×11 imperial thread mount, a 650mm SMA-K pigtail cable, and IP67 waterproofing with tested structural integrity after 3-meter drops, the EV288 is designed for direct installation on agricultural machinery masts, vehicle rooftops, and UAV platforms using the same mounting hardware as standard survey and precision agriculture antennas. The SMA-K female connector interfaces with SMA-J male connectors on GNSS receivers, RTK modules, and autopilot GNSS ports used across professional precision agriculture and autonomous vehicle platforms worldwide.
