GNSS for eVTOL and Advanced Air Mobility

The HB10 is a compact boxed receiver with AsteRx-m3 Pro+, dual-antenna heading of 0.15° at 1 m, 100 Hz output and less than 10 ms latency. For integration inside an avionics bay, the HB59 OEM board offers the same engine with Ethernet and three UARTs. Pair either with the EV108 aviation antenna.

No. Eview receivers are commercial GNSS products, not certified avionics. They suit prototypes, flight test, research aircraft and large cargo UAV development. Certification of the aircraft and its navigation system remains the responsibility of the manufacturer and integrator, and we can supply datasheets to support your own assessment.

RAIM+ uses redundant measurements from multiple constellations to check that the position solution is consistent. It flags and can exclude faulty satellites and reports an integrity indication, so the flight control software can decide when to trust GNSS and when to rely on other sensors.

Galileo OSNMA lets the receiver confirm that navigation messages come from Galileo satellites, which helps detect spoofing over cities and near busy infrastructure. OSNMA is available on the HB10, HB59 and mosaic-X5 and mosaic-G5 receivers; it is not available on mosaic-H products such as the HB6 Pro and HB56H.

The EV108 is a 60 g, low-profile aviation antenna with a flange mount, 36 dB LNA and IP67 rating. For dual-antenna heading, mount two antennas as far apart as the airframe allows; 1 m spacing gives 0.15° heading, and a longer baseline improves it further.

An autonomous air taxi or eVTOL needs multi-band, multi-constellation GNSS with RTK or PPP accuracy, dual-antenna heading, integrity monitoring and strong protection against jamming and spoofing, combined with inertial sensors for continuity.

Yes. RTK gives centimetre positioning for precision landing, vertiport approaches and cargo drop-off. Production aircraft combine it with inertial navigation and integrity checks required by aviation authorities.
