Robotics & UGVs GNSS Antenna Solutions
Reliable positioning systems for ground-based autonomous robots operating in complex RF and structural environments.
HelioNavi delivers high-reliability, low-profile GNSS antennas that ensure centimeter-level precision for global autonomous systems across logistics, agriculture, industry, and defense. Our GNSS antenna is specifically engineered to maintain sub-centimeter stability for ground-based platforms, overcoming severe chassis vibrations, dense structural occlusions, and harsh multipath environments.
GNSS Antenna Challenges in Robotics & UGVs
Strict SWaP Constraints
Robotics demand compact, lightweight designs that maintain high RF efficiency to fit sleek industrial profiles and minimize collision risks.
Ground-Level Occlusion
Operating near the terrain increases signal blocking from buildings and foliage, causing frequent cycle slips and slower RTK recovery.
Intense Multipath Interference
Reflections from ground surfaces and structures create noise that degrades RTK fix rates and causes positioning drift.
Complex Near-Field Coexistence
Proximity to high-power motors, AI processors, and wireless sensors leads to RF desensitization via electromagnetic interference.
Dynamic Vibration Instability
Constant shock from rugged terrain requires robust internal stabilization to prevent signal tracking degradation.
Core Engineering Capabilities
Full-Constellation Tracking
Simultaneous multi-band support (L1/L2/L5) across GPS, GLONASS, Galileo, and BeiDou for rapid RTK initialization in obstructed environments.
Optimized Low-SWaP
Compact, low-profile, or embedded designs maintain high gain without adding bulk to the robotic platform.
Phase Center Stability
Sub-millimeter PCV control remains precise even under severe mechanical shock and vibration.
Bespoke RF Integration
Custom anechoic chamber tuning and chassis optimization maximize gain and isolate co-site EMI.
