ArduSimple GNSS/RTK Receivers: Built-In Resilience Against Jamming & Spoofing

With GNSS reliability increasingly threatened by jamming and spoofing, ensuring the resilience of navigation systems has become essential. Read more >>

For applications such as reference networks and drone surveillance, the degradation or loss of GNSS signals can have severe consequences.

ArduSimple aims to deliver solutions capable of maintaining uninterrupted performance, even in challenging environments.

The simpleRTK3B Series receivers, powered by Septentrio’s Mosaic-X5 module, provide robust resilience against GNSS jamming and spoofing.

Understanding Jamming and Spoofing

Jamming involves interference with GNSS signals through the emission of radio frequency noise, which can cause a loss of the navigation and timing information that GNSS receivers provide, reducing their accuracy and reliability.

Spoofing, a more sophisticated interference, occurs when a malicious attacker introduces false signals to a GNSS receiver to manipulate its positioning output. During such attacks, the GPS receiver reports incorrect locations.

JammerTest

A key component of ArduSimple’s simpleRTK3B Series, Septentrio’s advanced receivers were tested during JammerTest 2023 in Norway, an event simulating live interference conditions.

Septentrio’s receivers with AIM+ anti-jamming and anti-spoofing technology were tested across a range of interference scenarios, from simple jammers to sophisticated spoofing attacks.

AIM+ Detection and Mitigation of GNSS Jamming
During real-time GNSS interference, Septentrio receivers installed in the test vehicle maintained accurate positioning, while competitor receivers eventually lost positioning data.

AIM+ detects, flags and mitigates GNSS spoofing
Septentrio receiver (orange tracks) mitigates GNSS spoofing and shows accurate positioning along the coastal road, while competition receivers (blue, green, red track) are spoofed and show erroneous positions.

Consistent Detection of GPS Spoofing
Septentrio receivers consistently identified GPS spoofing, as indicated by red bars highlighting undetected spoofed positions with significant errors.

Multiple mechanisms work in tandem within Septentrio receivers to detect spoofing and flag spoofed locations with large discrepancies.

OSNMA Galileo Signal Authentication Detects Spoofing
During a spoofing attack, Galileo’s OSNMA authentication mechanism detected spoofing, as visible in the receiver’s Web User Interface.
