Frequently Asked Questions
How accurate is a Septentrio GNSS receiver?
Septentrio GNSS receivers deliver centimeter-level accuracy: 0.6 cm + 0.5 ppm horizontal and 1.0 cm + 1.0 ppm vertical with RTK corrections. With Galileo HAS (free satellite-delivered corrections), accuracies of 10–15 cm are achievable without a local base station. In standalone mode (no corrections), accuracy is typically 1.0–2.5 meters depending on satellite geometry and ionospheric conditions.
What is the best GNSS receiver for drones?
The best GNSS receiver for drones depends on your application. For drone mapping and surveying, the HB6 powered by Septentrio mosaic-X5 offers the best balance of accuracy (cm-level RTK), weight, and AIM+ anti-jamming protection. For drone base stations and delivery operations requiring 4G LTE connectivity, the HB21 is the recommended choice. For lightweight eVTOL and small UAV integration, the EV322 provides the smallest form factor.
What makes Septentrio GNSS different from other brands?
Septentrio’s key differentiator is AIM+ anti-jamming and anti-spoofing technology, which provides up to 60 dB of interference suppression — over 2× better than typical alternatives (20–25 dB for u-blox, Trimble). Septentrio also offers APME+ multipath mitigation, dual-antenna heading (mosaic-G5 P3H), and native support for ArduPilot and PX4 autopilots via SBF protocol. The mosaic-X5 tracks 448 channels across GPS, GLONASS, Galileo, and BeiDou simultaneously.
How do I choose the right GNSS receiver for my project?
Consider these factors: (1) Required accuracy — cm-level RTK vs meter-level standalone; (2) Environment — does the receiver need anti-jamming protection?; (3) Integration — OEM module for custom builds or ready-to-use box receiver?; (4) Heading — does your application need dual-antenna heading?; (5) Connectivity — do you need 4G LTE for NTRIP corrections? Our FAQ page has a detailed selection guide.
Can GNSS receivers be jammed?
Yes, standard GNSS receivers are vulnerable to jamming because satellite signals are extremely weak when they reach Earth. However, Septentrio’s AIM+ technology is specifically designed to counter this — it filters out interference in real time, allowing receivers to maintain centimeter-level positioning even when jamming signals are 60 dB stronger than the GNSS signal. This makes AIM+-equipped receivers ideal for defense operations, drone shows, and critical infrastructure applications.
Do these receivers work with Pixhawk / PX4 / ArduPilot?
Yes. Septentrio receivers output SBF protocol which is natively supported by ArduPilot (GPS_TYPE=9) and PX4 (GPS_TYPE=9). The HB21 and HB6 Pro also output standard NMEA. Integration typically requires connecting 4 wires (VCC, GND, TX, RX) and setting the correct GPS type in the flight controller firmware. See our FAQ for detailed setup guides.
