Description
Product Overview- HB6 Pro GNSS Box Receiver with Integrated 4G LTE
RTK GNSS Receiver | 4G LTE Connectivity | Dual-Antenna Heading | 448 Channels | AIM+ Anti-Interference | Ultra-Compact | UAV & Autonomous Systems
The HB6 Pro GNSS Box Receiver with 4G — powered by Septentrio Mosaic X5 — is a compact, connected, high-precision multi-band RTK GNSS receiver engineered for autonomous and unmanned applications that demand both centimeter-level positioning accuracy and real-time field connectivity. With its built-in 4G LTE connectivity, the HB6 Pro can directly receive NTRIP RTK correction data over cellular networks, transmit positioning information in real time, and enable remote device monitoring and configuration. This eliminates the need for external cellular modems or radio correction systems, simplifying system architecture for field deployments.
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 tracking all visible satellites simultaneously. RTK horizontal accuracy of 0.6 cm + 0.5 ppm and RTK vertical accuracy of 1 cm + 1 ppm, combined with a 7-second RTK initialization time, deliver fast, reliable centimeter-level fixes for precision drone flight, autonomous ground vehicle navigation, and robotic guidance systems.
The dual-antenna Mosaic-H configuration enables real-time heading and pitch/roll output with orientation accuracy of 0.03° at 5-meter antenna spacing — providing compass-free heading for magnetically disturbed environments. Built on Septentrio’s proven signal integrity platform, the HB6 Pro integrates AIM+ active interference detection and suppression, 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 — delivering unmatched signal resilience for high-vibration, fast-moving, and RF-contested operational environments.
With a compact footprint of just 68.4 × 41.8 × 13.5mm, operating voltage of 4.5V to 12V at 185mA, operating temperature range of -40°C to +85°C, and support for NMEA 0183, SBF, RINEX, RTCM, and CMR/CMR+ output formats, the HB6 Pro is the ideal GNSS solution for OEM integration into the most demanding autonomous and unmanned platforms worldwide.

Anti-Interference Technology — Detailed
AIM+ (Active Interference Monitoring & Mitigation)
Detects and suppresses broadband, narrowband, and swept jamming signals in real time. Includes interference indicator, active mitigation, and spectrum measurement functions. Ensures reliable RTK positioning even in congested RF environments including urban airspace, industrial automation zones, and electronically contested areas.
APME+ (Advanced Phase Multipath Estimation)
Septentrio’s patented multipath suppression algorithm. Separates direct GNSS signals from signals reflected by nearby buildings, terrain, or infrastructure. Critical for UAV operations in urban environments, precision agriculture near farm structures, and autonomous ground vehicle navigation in complex surroundings.
IONO+ (Ionospheric Scintillation Suppression)
Provides advanced protection against ionospheric interference, particularly in equatorial regions, polar operations, and during solar weather events. Maintains carrier phase lock and RTK fix stability where standard receivers would degrade or lose signal entirely.
Lock+ (Anti-Shock & Vibration Robustness)
Enables robust signal tracking at high vibrations and mechanical shocks. Purpose-built for drone motor vibration, ground vehicle engine vibration, and rapid platform maneuvers — maintaining continuous satellite lock during high-dynamic flight and driving profiles critical for 4G-connected autonomous operations.
RAIM+ (Receiver Autonomous Integrity Monitoring)
Continuously monitors the integrity of GNSS positioning solutions in real time. Automatically detects and excludes faulty satellite signals — essential for safety-critical autonomous navigation, precision approach and landing, and any application where undetected positioning errors are unacceptable.
OSNMA (Open Service Navigation Message Authentication)
Verifies the authenticity of Galileo navigation messages in real time to detect and reject spoofed GNSS signals. Provides hardware-level spoofing protection for security-sensitive autonomous platforms operating over 4G-connected networks.
