Anti-Jamming & Anti-Spoofing GNSS Receiver with AIM+
An anti-jamming GNSS receiver keeps tracking satellites when radio interference is present. Every Eview receiver, from the HB6 and HB10 to the HB50 and HBEV11, is powered by Septentrio modules with AIM+ built in and on by default, removing narrowband, wideband, chirp and pulsed interference and checking signals for spoofing.

What AIM+ handles and how
| Threat | Typical source | What AIM+ does |
|---|---|---|
| Narrowband (CW) | Single-tone jammers, harmonics from on-board electronics | Detects the tone and notches it out of the band |
| Multi-frequency narrowband | Several tones across one or more GNSS bands | Tracks and removes each tone separately |
| Wideband and chirp | Personal privacy devices (in-car jammers), swept-frequency jammers | Filters the wideband energy so satellites can still be tracked |
| Pulsed | Radar, aviation DME and other pulsed transmitters | Blanks the pulses and keeps the clean part of the signal |
| Spoofing | Fake GNSS signals transmitted locally | Signal-consistency checks on timing, Doppler, geometry, frequencies and constellations |
| Navigation data forgery | Spoofed Galileo navigation messages | Galileo OSNMA authenticates the navigation data (mosaic-X5 and mosaic-G5 products) |
AIM+ is part of every Septentrio receiver and is enabled by default. For the difference between the two threats, read anti-jamming vs anti-spoofing.

Where anti-jamming matters
How to choose and install
Interference source detection and tracing
Every Eview receiver is a GNSS receiver with interference source detection built in. Septentrio AIM+ watches each band in real time, so engineers can see that interference is present, what kind it is and when it happens.
Anti-jamming GNSS: frequently asked questions
Eview receivers built on the Septentrio mosaic-X5 and mosaic-G5, such as the HB6, HB56, HB52 and HBEV322, combine centimetre RTK with AIM+ spoofing detection and Galileo OSNMA navigation message authentication. Every Eview receiver includes AIM+ interference mitigation.
For drones, choose a multi-band receiver with active interference mitigation, because single-band receivers lose lock first near radio links and video transmitters. The HB52 and HBEV322 (mosaic-G5) are light enough for small drones, and the HB10 adds 100 Hz output and dual-antenna heading for fast platforms. All include Septentrio AIM+.
It is a receiver that detects radio interference in the GNSS bands and removes it so it can keep tracking satellites. Eview receivers do this with Septentrio AIM+, which runs inside the module and handles narrowband, wideband, chirp and pulsed interference without extra hardware.
AIM+ (Advanced Interference Mitigation) is Septentrio’s interference and spoofing protection. It is built into every Septentrio receiver and on by default. It filters jamming, shows real-time spectrum plots and runs signal-consistency checks for spoofing, and on mosaic-X5 and mosaic-G5 it works with Galileo OSNMA.
Jamming drowns GNSS signals in noise, so the receiver loses tracking. Spoofing sends fake signals so the receiver computes a wrong position. AIM+ removes jamming and checks signal consistency, and OSNMA authenticates Galileo navigation data, so the two work as layers.
No. AIM+ works in the receiver, so a standard multi-frequency antenna is used. A good antenna mounted away from on-board noise sources still helps. The EV210 and EV220 suit drones, and the EV288 covers L5, E6 and L-band.
Yes. They connect over UART and output NMEA and SBF, with RTCM v3 corrections in. AIM+ runs in the receiver, so no flight controller settings are needed to use it. The HB6, HB10 and HB52 are common choices for ArduPilot and PX4 drones.
Yes, it can detect and characterise it. Septentrio-based Eview receivers with AIM+ detect interference in real time, classify it as narrowband or wideband, and show it on a built-in spectrum view, which helps engineers trace interference. Finding where the source physically is needs measurements from several receivers or a direction-finding antenna; one receiver tells you that interference is present, what type it is and how strong it is.
Yes. The mosaic-G5 includes AIM+, which detects and mitigates narrowband and wideband interference and flags spoofing, so Eview mosaic-G5 receivers report interference while keeping their position.
