RTK GNSS for Drones and UAVs

Eview RTK GNSS receivers give drones centimetre positioning, true dual-antenna heading and output up to 100 Hz, powered by Septentrio modules with AIM+ anti-jamming. Choose an ultralight receiver, an all-in-one smart antenna or a 100 Hz heading receiver for mapping, inspection, spraying and delivery drones.

What drones need

What a drone needs from its GNSS receiver

Centimetre accuracy
RTK accuracy of 0.6 cm + 0.5 ppm with about 7 s initialisation, so mapping and LiDAR data line up without ground control points. See RTK positioning.
Reliable heading
Magnetometers are disturbed by motors and batteries. Dual-antenna GNSS heading gives 0.15° at 1 m spacing, from standstill. See how dual-antenna heading works.
Resistance to interference
Video links, telemetry radios and power lines jam GNSS. Septentrio AIM+ suppresses interference and Galileo OSNMA protects against spoofing. See anti-jamming receivers.
Fast, low-latency output
Flight control needs fresh positions. The HB10 and HB6 output up to 100 Hz; mosaic-G5 receivers run at 20 Hz with less than 10 ms latency.
Low weight and power
From the 48 × 35 mm HB52 to the all-in-one HBEV322 smart antenna, receivers are sized for small airframes and limited power budgets.
Stable tracking in flight
LOCK+ keeps tracking through vibration and fast manoeuvres, and IONO+ protects RTK during ionospheric scintillation.

Use cases

Drone applications

Mapping and photogrammetry
Centimetre RTK or PPK georeferencing with fewer or no ground control points. See RTK vs PPK.
Inspection and patrol
Stable positioning near power lines, pipelines and bridges, where interference is common. See inspection drones.
Agricultural spraying
Accurate swaths and heading for crop-spraying drones. See precision agriculture.
Delivery and logistics
Anti-spoofing and dual-antenna heading for waypoint navigation in urban airspace.
Construction surveys
Site progress mapping, stockpile volumes and earthworks checks. See construction and mining.
eVTOL and larger UAVs
100 Hz, low-latency position and attitude for advanced air mobility. See eVTOL.
Integration

Easy to integrate

Autopilots
UART output in NMEA and Septentrio SBF for ArduPilot and PX4, including GPS yaw. See our ArduPilot guide.
Corrections
RTCM v3 corrections from an NTRIP caster, CORS network or your own base such as the HB62 base station. See NTRIP and RTCM.
Logging and PPK
On-board microSD or SD logging of raw data, converted to RINEX for post-processing. Firmware and manuals on firmware downloads.
FAQ

Drone GNSS: frequently asked questions

Which Eview GNSS receiver is best for my drone?

For small and medium drones, the HB52 (ultralight, mosaic-G5) or the all-in-one HBEV322 smart antenna. For position plus true heading, the HB51 or HB52H with two antennas. For fast platforms that need 100 Hz output and less than 10 ms latency, the HB10 with Septentrio AsteRx-m3 Pro+.

Do I need dual-antenna heading on a drone?

Dual-antenna heading gives a true heading of 0.15° at 1 m antenna spacing without relying on the magnetometer, which is easily disturbed by motors, batteries and power lines. It is recommended for inspection near power lines, spraying drones and heavy-lift platforms.

Do Eview receivers work with ArduPilot and PX4?

Yes. Eview receivers connect over UART and output standard NMEA and Septentrio SBF, which ArduPilot and PX4 support, including GPS yaw from dual-antenna receivers. RTK corrections are accepted in RTCM v3 format.

Should I use RTK or PPK for drone mapping?

RTK gives centimetre positions in real time when a correction link is available. PPK logs raw data and corrects it after the flight, which is more robust when the link drops. Eview receivers support both: RTCM input for RTK and raw data logging (SBF to RINEX) for PPK.

How do Eview receivers handle GNSS jamming on drones?

Septentrio AIM+ detects and suppresses narrowband and wideband interference from radio links, video transmitters and nearby equipment, and Galileo OSNMA authenticates signals against spoofing. This keeps RTK available close to power lines, telecom masts and urban RF noise.
