Description

The Holybro CH3602A High Precision RTK GNSS Antenna is engineered for demanding UAV applications requiring reliable, high-accuracy positioning. Its triple-band reception capability ensures robust satellite tracking across multiple global navigation constellations, even in challenging signal environments such as near tree lines or urban canyons. The antenna’s stable phase center and minimized phase center variation (PCV) are critical for maintaining the integrity of Real-Time Kinematic (RTK) corrections.

Built with an IP67-rated enclosure, the antenna is protected against dust and temporary immersion, making it suitable for agricultural, surveying, and inspection drones operating in varied conditions. The compact, lightweight form factor minimizes payload impact while the SMA connector provides a secure, industry-standard interface for integration with compatible flight controllers and RTK receivers.

Key Features

  • Triple-Band GNSS Reception: Captures L1, L2, and L5 frequency bands for enhanced signal reliability and multi-constellation support.
  • High-Precision Phase Center: Engineered for minimal phase center deviation, ensuring consistent millimeter-level accuracy for RTK and PPK workflows.
  • Rugged IP67 Design: Fully sealed housing protects internal components from moisture, dust, and vibration in outdoor and industrial environments.
  • Wide-Angle Circular Polarization (WACP): Improves signal acquisition from low-elevation satellites and maintains performance during dynamic flight maneuvers.
  • Low-Weight, Low-Power Profile: At just 25 grams, the antenna adds minimal mass and draw to the UAV's power system, extending flight times.
  • Extended Operational Temperature Range: Functions reliably in storage temperatures from -40°C to +70°C and up to 95% non-condensing humidity.

Applications

  • Precision agriculture and crop-spraying (plant protection) drones requiring centimeter-accurate swath guidance.
  • UAV power line inspection and corridor mapping in environments with partial sky obstruction.
  • GIS surveying, mapping, and cadastral surveys where high-accuracy geotagging is essential.
  • Cinematic drone filming platforms utilizing RTK for precise, repeatable shot positioning.
  • Search and rescue or infrastructure inspection drones operating in challenging weather conditions.

Frequently Asked Questions

What flight controllers is the Holybro CH3602A antenna compatible with?

The antenna features a standard SMA male connector, making it directly compatible with Holybro's own Pixhawk-series flight controllers (like the Pixhawk 6X) and any other GNSS module or flight controller with a matching SMA female port. It is designed for use with RTK-capable systems.

What is the actual positioning accuracy achievable with this antenna?

When paired with a compatible RTK base station and receiver, the CH3602A antenna supports centimeter to millimeter-level positioning accuracy in Real-Time Kinematic (RTK) mode. Its stable phase center and triple-band reception are key to achieving this high precision.

Can this antenna be used in rainy conditions or for marine drones?

Yes, the IP67 rating provides protection against temporary immersion in water up to 1 meter for 30 minutes and is dust-tight. This makes it suitable for operation in rain, snow, and humid environments, including applications over water, though prolonged submersion is not recommended.

Does the antenna require any specific configuration or setup in the flight controller software?

No specific antenna configuration is typically required. After physically connecting it to your GNSS module's SMA port, you configure your flight stack (e.g., ArduPilot, PX4) to use the connected GNSS receiver for positioning. Ensure your RTK setup (base station, correction link) is correctly configured in the ground control software.
