Product Overview- HB6 GNSS Box Receiver

RTK GNSS Receiver | Dual-Antenna Heading | 448 Channels | AIM+ Anti-Interference | 45g Ultra-Compact | UAV & Autonomous Systems

The HB6 GNSS Box Receiver — powered by Septentrio Mosaic X5 — is a compact, lightweight, high-precision multi-band RTK GNSS receiver engineered for the most demanding autonomous, unmanned, and precision control applications. At just 45 grams and 68.4 × 41.8 × 13.5mm, the HB6 is among the smallest and lightest RTK GNSS receivers on the market without any compromise on tracking performance, signal integrity, or anti-interference capability.

The Septentrio Mosaic X5 engine provides full multi-constellation, multi-frequency tracking across GPS, BeiDou, GLONASS, Galileo, NavIC, QZSS, and SBAS — with 448 hardware channels simultaneously tracking all visible satellites. RTK horizontal accuracy of 0.6 cm + 0.5 ppm and vertical accuracy of 1 cm + 1 ppm, combined with a fast 7-second RTK initialization time and 1-second signal reacquisition, ensure rapid, reliable centimeter-level positioning fixes for precision drone flight, autonomous ground vehicle navigation, and robotic guidance systems.

Available in both single-antenna (Mosaic X5) and dual-antenna (Mosaic-H) configurations, the HB6 supports real-time heading and pitch/roll output with orientation accuracy of 0.03° at 5-meter antenna spacing — providing compass-free, magnetically immune heading for UAVs, autonomous surface vessels, and driverless vehicles operating in electrically noisy environments.

Built on Septentrio’s proven signal integrity platform, the HB6 integrates AIM+ active interference detection and suppression with spectrum measurement, APME+ multipath mitigation, IONO+ ionospheric scintillation suppression, Lock+ anti-shock and vibration tracking robustness, and RAIM+ receiver autonomous integrity monitoring — with OSNMA anti-spoofing support for Galileo signals. The result is a receiver that maintains reliable centimeter-level RTK positioning through high-vibration UAV flight, fast ground vehicle maneuvers, and RF-contested operating environments where standard GNSS modules fail.

With operating voltage of 4.5V to 12V, current consumption of 185mA at 5V, operating temperature range of -40°C to +85°C, support for NMEA 0183, SBF, RINEX, RTCM, and CMR/CMR+ output formats, and baud rates up to 4 Mbps, the HB6 is the ideal OEM GNSS module for weight-sensitive UAV platforms, battery-powered robotics, and compact autonomous systems requiring maximum precision in minimum space.

Anti-Interference Technology — Detailed

AIM+ (Active Interference Monitoring & Mitigation)

Detects and suppresses broadband, narrowband, and swept jamming signals in real time. Features built-in interference indicator, active mitigation engine, and spectrum measurement functions — ensuring reliable RTK positioning in congested RF environments including urban drone corridors, industrial automation facilities, and electronically contested areas. Essential for professional UAV operations where RF interference is unavoidable.

APME+ (Advanced Phase Multipath Estimation)

Septentrio’s patented multipath suppression algorithm that separates direct GNSS signals from reflected signals caused by buildings, terrain, and infrastructure. Provides clean carrier phase measurements for UAV operations near structures, autonomous ground vehicles navigating urban environments, and precision agriculture systems working adjacent to farm buildings and equipment.

IONO+ (Ionospheric Scintillation Suppression)

Provides advanced real-time protection against ionospheric interference — particularly critical in equatorial regions, polar deployments, and during solar weather events. Maintains carrier phase lock and full RTK fix stability in conditions that cause signal degradation or complete loss on standard GNSS receivers, ensuring continuous positioning for long-range drone missions and wide-area autonomous operations.

Lock+ (Excellent Tracking Robustness)

Delivers robust signal tracking at high vibration and mechanical shock. Purpose-engineered for UAV motor vibration, ground vehicle engine vibration, and rapid platform maneuvers — maintaining continuous satellite lock during the high-dynamic flight and drive profiles typical of plant protection drones, inspection UAVs, and autonomous ground vehicles.

RAIM+ (Receiver Autonomous Integrity Monitoring)

Continuously monitors and validates the integrity of GNSS positioning solutions in real time. Automatically detects and excludes faulty or degraded satellite signals without user intervention — essential for safety-critical autonomous navigation, precision UAV landing, and any unmanned platform where undetected positioning errors have operational or safety consequences.

OSNMA (Open Service Navigation Message Authentication)

Provides hardware-level verification of Galileo navigation message authenticity in real time. Detects and rejects spoofed GNSS signals before they affect the position solution — critical for autonomous platforms, fleet operations, and security-sensitive precision control systems where signal spoofing poses an operational threat.
