Yes, GNSS signals can absolutely be jammed by interference — and it is far easier than most engineers realize. GNSS satellites orbit roughly 20,000 km away, transmitting signals so weak they arrive at Earth’s surface with a power density of approximately −160 dBW/m², comparable to a 50-watt light bulb seen from 10,000 km. Any radio…
Yes, modern GNSS receivers can detect spoofing attacks — but not all of them. Standard consumer-grade GNSS chips have no built-in spoofing detection and will blindly trust fake satellite signals. Professional-grade receivers like those powered by Septentrio’s AIM+ technology use multi-layer signal monitoring, cryptographic authentication, and statistical anomaly detection to identify and flag spoofed signals…
If you need centimetre-level positioning across different environments and correction sources, you need a GNSS receiver that supports both RTK (Real-Time Kinematic) and PPP (Precise Point Positioning). Septentrio’s mosaic-X5 and mosaic-H(H) modules natively support both modes, giving engineers a flexible platform for UAVs, robotics, and autonomous vehicles — ready to use the best correction source…
If you’re evaluating high-precision GNSS receivers for a robotics, UAV, or surveying application, you’ve likely asked: how accurate is a Septentrio GNSS receiver in real-world conditions? The short answer is 0.6–2 cm horizontal RTK accuracy with 60–100 cm standalone positioning — but the more important answer is how Septentrio’s AIM+ anti-jamming and multi-frequency tracking maintain…
Yes — you can absolutely use an external anti-jamming GNSS receiver with DJI drones, and for professional operations in RF-contested environments, it is increasingly becoming a necessity. DJI’s onboard GNSS receivers, while adequate for basic flight, lack the anti-jamming and anti-spoofing capabilities needed for mission-critical work near power lines, cell towers, mining sites, or military…
The best GNSS receiver for marine navigation must deliver centimeter-level accuracy, robust anti-jamming performance, and multi-constellation tracking in one of the most challenging RF environments on earth. At sea, signal reflections off the water surface (multipath), interference from onboard electronics, and the complete absence of terrestrial correction networks make standard consumer-grade receivers unreliable for commercial…
If you’re flying professional drones in urban environments, near powerlines, or over industrial sites, the best GNSS receiver for drones with anti-jamming is a Septentrio-powered receiver with AIM+ technology. These receivers deliver 40–60 dB of interference suppression — far exceeding the roughly 25 dB you get from standard consumer-grade modules. For UAV operators who cannot…
Commercial drones rely on GNSS (GPS, GLONASS, Galileo, BeiDou) for positioning, navigation, and flight safety. But what happens when the signals your drone trusts are fake? GNSS spoofing is a sophisticated attack where false satellite signals are broadcast to trick a drone’s receiver into believing it is somewhere it is not — or that it…
What Is the Best GNSS Board for Robotics? Top Picks for OEM Integration The best GNSS board for robotics is the Septentrio mosaic-X5, thanks to its unique combination of RTK-grade centimeter accuracy, built-in AIM+ anti-jamming (40–60 dB), multi-constellation multi-frequency support, and a well-documented serial interface that integrates seamlessly with ROS, ArduPilot, and Pixhawk autopilots. For…
If you need centimeter-level positioning in areas where jammers, RF interference, or spoofing signals are known to be present, the best anti-jamming GNSS receiver on the market today is a Septentrio-based receiver equipped with AIM+ (Advanced Interference Mitigation) technology. The Septentrio mosaic-X5 and mosaic-H receivers deliver 40–60 dB of jamming suppression across multiple frequency bands,…
