Strict Low-SWaP Constraints
UAVs have very limited space, power, and payload. The antenna must deliver high
performance in a small footprint.
UAV & Drones
High-reliability GNSS antenna systems engineered for aerial platforms requiring stable positioning under severe airframe vibration, rapid attitude variations, and complex onboard EMI.
HelioNavi delivers precision-engineered UAV antenna technology, ranging from full-constellation, multi-frequency Helix and Patch arrays to advanced anti-jamming solutions. By maintaining sub-millimeter phase center stability and multi-stage out-of-band filtering, our GNSS antennas guarantee reliable signal tracking and rapid RTK initialization despite severe airframe vibrations and rapid attitude shifts. These high-performance GNSS antennas provide centimeter-level accuracy for mission-critical operations, including high-precision aerial surveying & LiDAR mapping, precision agriculture, environmental monitoring, industrial inspections, and emergency disaster relief.
UAV GNSS Performance Is Difficult in Real Applications
GNSS antenna performance in UAV systems is defined by complex operating environments rather than static datasheet specifications.
Dynamic Flight Attitude Variation
Vibration, rolling maneuvers, and attitude changes cause signal fluctuation and
phase center shifts.
RF Coexistence Environment
Telemetry, video link, LTE/5G modules, and cameras increase noise floor and
interference.
Low-Elevation Tracking Instability
Multipath and signal blockage are more severe at low elevation, impacting RTK
positioning reliability.
