Frequently Asked Questions

Which product is best for drone mapping? The HB6 is our most popular choice for drone surveying, offering mosaic-X5-grade RTK accuracy in a compact form factor.

Do these receivers work with Pixhawk / PX4 / ArduPilot? Yes. All Septentrio-based receivers output SBF protocol which is natively supported by ArduPilot (GPS_TYPE=9) and PX4 (GPS_TYPE=9). The HB21 also provides standard NMEA output.

Can I use these without an RTK base station? Yes. Use NTRIP corrections via our HB21’s internal 4G modem, or leverage Galileo HAS for free satellite-delivered centimeter-level corrections.

What is the delivery time? We ship from stock within 2-4 business days. Express shipping available for urgent orders.

Do you offer OEM pricing? Yes — contact us at sales@uav-gnss.com for volume and OEM pricing.
