HBEV11 Integrated RTK GNSS Antenna — Septentrio mosaic-G5 P3
The HBEV11 is an all-in-one full-frequency RTK GNSS receiver in a 85 mm low-profile antenna housing. Powered by the Septentrio mosaic-G5 P3, it integrates the receiver, LNA, SAW filter, full-band patch antenna, and backup battery into a single 0.44 W module — delivering 0.6 cm RTK accuracy over UART, USB, or RS232 for weight-sensitive UAVs, robots, and space-constrained automation platforms.
Description
All-in-One RTK GNSS Receiver in a Low-Profile Antenna Form Factor
The HBEV11 integrates a complete RTK GNSS receiver into an 85 × 10 mm patch-antenna housing. Built on the Septentrio mosaic-G5 P3, it combines the GNSS engine, LNA, SAW filter, full-band patch antenna, and backup battery in a single sealed module. No separate antenna, no antenna cable, no external LNA — just a standard M12-4P connector with a 10 m cable. At ~0.44 W on 3.3 V, it is purpose-built for battery-powered UAVs, collaborative robots, and any platform where size, weight, and power draw must be minimised without sacrificing positioning precision.

Applications
The HBEV11’s plug-and-play integration — receiver, antenna, and battery in one unit — makes it ideal for fixed-wing and multirotor UAVs where every gram and milliwatt counts, AGVs and mobile robots operating indoors/outdoors, warehouse automation equipment, and any embedded system requiring a self-contained GNSS positioning solution without external antenna routing complexity.
