How MGB-Tech re-engineered PSA Antwerp’s straddle carrier GNSS receivers on Septentrio mosaic-X5 in under three months — centimetre-level RTK, multipath suppression and no operational downtime in a steel-loaded port environment.
How Galileo High Accuracy Service works — SL1/SL2 targets, E6-B and NTRIP (IDD) access, supported Septentrio Mosaic-G5 modules, and measured Mosaic-G5 P3H results: 10 cm in open sky.
The short answer: GPS is a single satellite constellation operated by the United States, while GNSS (Global Navigation Satellite System) is the umbrella term for all satellite navigation constellations — GPS, GLONASS, Galileo and BeiDou. A GNSS receiver tracks satellites from several constellations at once, whereas a GPS-only receiver can only use US satellites. For…
The Septentrio mosaic-X5 is a compact OEM GNSS receiver module that packs 448 hardware channels of multi-constellation, multi-band tracking, centimetre-level RTK, and Septentrio’s AIM+ anti-jamming into a board measuring just 71 × 59 × 12.7 mm. In short: it is a complete high-precision positioning engine built to be embedded in UAVs, robots, survey instruments and…
Short answer: a GNSS receiver with heading uses two antennas a known distance apart and compares their carrier-phase signals to measure the direction the vehicle points, even when it is stationary. With a 1 m baseline, Septentrio-based receivers reach about 0.15°, and longer baselines are more accurate. Eview heading receivers include the HB6 Pro, HB52H…
The best GNSS receiver for Pixhawk is a multi-band, multi-constellation RTK module that outputs UBX, NMEA, or SBF over UART — and for professional operations that means a Septentrio-based receiver such as the mosaic-X5 used in Eview’s industrial products, which adds 40–60 dB of AIM+ anti-jamming to centimeter-level RTK. Hobby builds do fine with a…
For ArduPilot, the best GNSS module is one that speaks standard UBX or NMEA over UART (or DroneCAN), updates at 5–10 Hz, and matches your mission: a u-blox M8N or M9N for basic flight, a u-blox ZED-F9P or Septentrio mosaic-X5 for RTK centimetre accuracy, and a Septentrio module with AIM+ anti-jamming when you operate near RF…
Septentrio AIM+ anti-jamming GNSS receivers held centimeter-level RTK through ~100 jamming and spoofing scenarios at Jammertest 2025 — while competitor receivers showed errors of meters and >10 m.
How Septentrio’s official ROSaic driver (septentrio_gnss_driver) integrates GNSS and GNSS/INS receivers with ROS 1 & ROS 2: driver architecture, INS YAML configuration, NED/ENU coordinate frames, multi-source RTK, and integration effort versus a self-developed driver.
Short answer: for drone mapping in 2026, pick a multi-band RTK receiver that also logs raw data for PPK backup. The Septentrio mosaic-G5 and mosaic-X5 add AIM+ interference mitigation and Galileo OSNMA, and the mosaic-X5 outputs up to 100 Hz. The u-blox ZED-F9P suits low-cost builds and the Unicore UM982 suits budget dual-antenna heading. Eview…
