Last updated: October 2026 Short answer: Choose RTK when you need centimetre accuracy in real time and you can count on a correction link for the whole flight. Choose PPK when that link may drop — hilly terrain, long range, urban canyons — because accuracy can be recovered afterwards. Most professional mapping crews run both…
Anti-jamming keeps a receiver tracking when radio interference drowns the satellite signals; anti-spoofing stops it from trusting fake signals. Every Eview GNSS receiver has both layers: Septentrio AIM+ interference mitigation is on by default, and Eview receivers built on the mosaic-X5 and mosaic-G5 add Galileo OSNMA authentication. This guide explains the difference and which Eview…
NTRIP, RTCM, and RINEX: A Complete Guide to GNSS Correction Data Formats for Engineers If you work with RTK GNSS for UAVs, autonomous vehicles, or precision surveying, you need to understand three acronyms: NTRIP, RTCM, and RINEX. They are the foundation of how centimeter-accurate positioning gets from a reference station to your moving receiver. This…
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…
An Eview receiver powered by a Septentrio module is rated at 0.6 cm + 0.5 ppm horizontal and 1 cm + 1 ppm vertical in RTK, with about 7 s initialisation. At 10 km from the base, the distance term adds about 5 mm horizontally. Holding that accuracy in the field depends on the antenna,…
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…
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…
The best GNSS board for a robot gives centimetre RTK, true heading without a magnetometer, low power and a clean interface to ROS or the autopilot. Eview’s robotics line covers this with the HBEV322 / HBEV322H smart antenna, the HB52 / HB52H and HB50H receivers, the HB51 heading board and the HB59 OEM board, all…
