Overview

Why GNSS Matters for Professional UAVs

Every UAV application depends on reliable, accurate positioning. For centimeter-level mapping accuracy, PPK/RTK processing eliminates ground control point dependency. For inspection drones near power lines, AIM+ prevents position loss in high-RF environments.

Eview Septentrio-based modules track five constellations simultaneously, achieve RTK fix in under 10 seconds, and output position at 100 Hz — meeting PX4 and ArduPilot requirements. AIM+ provides up to 60 dB of active jamming suppression across all frequency bands.

FAQ

UAV GNSS — Frequently Asked Questions

What GNSS accuracy do professional mapping UAVs require?
Professional photogrammetric mapping UAVs need ≤2 cm positioning accuracy for reliable georeferencing without ground control points. Eview RTK/PPK receivers deliver <1 cm + 0.5 ppm horizontal accuracy — sufficient for cadastral survey, topographic mapping, and volumetric calculations.
Are Eview GNSS modules compatible with ArduPilot and PX4?
Yes. Eview modules output standard NMEA 0183 and UBX binary messages via UART, making them directly compatible with ArduPilot and PX4 GPS driver interfaces. The Mosaic Click, Linnet Mosaic-X5, and M-2 GNSS Board all support this integration.
What is the difference between RTK and PPK for drone mapping?
RTK provides live centimeter corrections during flight via a radio or cellular link. PPK records raw GNSS data and applies corrections after landing — recovering accuracy even when the RTK link is intermittent. Eview receivers support both workflows from the same hardware.
How does AIM+ anti-jamming protect UAV operations?
AIM+ actively detects and suppresses radio frequency interference across all GNSS bands — up to 60 dB of suppression. For drones near power lines, cell towers, or in urban RF environments, AIM+ maintains RTK lock where standard receivers would lose position and trigger a failsafe.
