Septentrio mosaic-X5 GNSS Receiver — Eview Integration Guide
Eview GNSS Technology integrates the Septentrio mosaic-X5 — Septentrio’s flagship compact OEM GNSS receiver module — into a complete range of professional RTK receivers and smart antennas. This page covers mosaic-X5 specifications, performance benchmarks, and the Eview products powered by it.
The Septentrio mosaic-X5 is widely regarded as the most resilient compact GNSS receiver module available for professional civilian applications. It combines full-frequency, all-constellation tracking with Septentrio’s AIM+ anti-jamming and SLAS anti-spoofing in a module measuring just 71 × 59 × 12.7 mm — making it the chipset of choice for UAV integrators, survey equipment manufacturers, and machine control OEMs worldwide.

What Makes mosaic-X5 Different
AIM+ Anti-Jamming: Hardware-Level RF Protection
Most GNSS chipsets implement interference mitigation in software, after signals have entered the correlator. Septentrio’s AIM+ operates in the RF hardware front-end — before the signal reaches the digital processing chain. Narrowband jammers are detected and notch-filtered, wideband interference from industrial equipment and 5G base stations is attenuated in real time, and pulse interference from radar is blanked before it corrupts measurements. Position accuracy is maintained under interference levels that cause complete signal loss in competing receivers.
FAST6 RTK Engine: Sub-10 Second Fix Times
Septentrio’s FAST6 algorithm resolves carrier phase integer ambiguities in under 10 seconds on triple-frequency (L1+L2+L5) signals — a critical advantage for drone operations, machine control, and vehicle-mounted survey where rapid RTK re-acquisition after signal blockage directly impacts productivity.
Full-Frequency Tracking: L1 + L2 + L5 on All Constellations
The mosaic-X5 tracks L1, L2, and L5 on GPS; E1, E5a, E5b, E6 on Galileo; B1, B2, B3 on BeiDou; G1, G2, G3 on GLONASS; and L1, L5 on QZSS and NavIC. This comprehensive frequency coverage provides ionospheric correction redundancy and faster RTK initialisation in challenging environments.

mosaic-X5 Applications
UAV and Drone Navigation
The mosaic-X5’s low power consumption (1.1 W), compact module footprint, and AIM+ anti-jamming make it the preferred choice for professional drone GNSS payloads. The HBEV11 integrates mosaic-X5 with antenna and LTE modem in a single dome, reducing wiring complexity and weight for UAV integrators.
Land Surveying and Mapping
The mosaic-X5 supports all CORS network protocols (VRS, FKP, MAC) and outputs RINEX 3 for post-processing in Leica Infinity, Trimble Business Centre, and RTKLIB. The HB6 Pro 4G enables single-operator network RTK with integrated LTE — no separate data modem required.
Machine Control (Construction and Agriculture)
100 Hz position update rate and sub-10-second RTK initialisation make mosaic-X5 ideal for excavator blade control, motor-grader automation, and auto-steer tractor guidance. The HB6‘s CANbus interface connects directly to most machine control ECUs.
Autonomous Vehicles and Robotics
The mosaic-X5’s Ethernet 100Base-T interface, 100 Hz output rate, and raw SBF measurement output enable tight integration with ROS (Robot Operating System), automotive sensor fusion stacks, and custom autonomous navigation systems.

Frequently Asked Questions
What is the Septentrio mosaic-X5?
The Septentrio mosaic-X5 is a compact OEM GNSS receiver module tracking 448 channels across GPS, GLONASS, Galileo, BeiDou, QZSS, and NavIC on L1, L2, and L5 frequencies. It includes AIM+ hardware anti-jamming and SLAS anti-spoofing, achieving 1 cm + 1 ppm RTK horizontal accuracy with sub-10-second initialisation.
How does mosaic-X5 compare to u-blox F9P?
The mosaic-X5 offers more channels (448 vs 184), hardware-level AIM+ anti-jamming (the F9P has no hardware anti-jamming), higher update rate (100 Hz vs 20 Hz), and Ethernet connectivity. The mosaic-X5 targets demanding professional applications; the F9P targets the hobbyist and entry-level market. Eview GNSS integrates only Septentrio chipsets.
Which Eview products use the Septentrio mosaic-X5?
Five Eview products are powered by mosaic-X5: the HB6, HB6 Pro 4G, HB52/HB52H, HB51, and HBEV11. The HB6 Pro 4G is most popular for network RTK survey; the HBEV11 is the leading choice for UAV integration.
Does mosaic-X5 support RTK and PPK simultaneously?
Yes. The mosaic-X5 outputs real-time RTK NMEA streams while simultaneously logging raw GNSS observations in SBF and RINEX 3 for PPK post-processing. No external logging hardware is required.
What is AIM+ and is it included in Eview receivers?
AIM+ (Advanced Interference Mitigation Plus) is Septentrio’s hardware-level anti-jamming system. It detects, notches, and filters RF interference at the front-end stage before the signal reaches the digital correlator. AIM+ is included as standard in all mosaic-X5-based Eview receivers.
Can I connect a mosaic-X5 receiver to NTRIP?
Yes. The HB6 Pro 4G and HBEV11 include integrated 4G LTE modems for direct NTRIP connectivity. The HB6, HB52, and HB51 connect to NTRIP via an external device through USB or serial interface using standard RTCM 3.x correction streams.
