Drone RTK case
UM982 for UAV Positioning Under Motion
Use UM982 when a drone project needs robust RTK logs, optional heading experiments, and a receiver path that can grow beyond basic dual-band RTK.
| Problem | Drone RTK fails when antenna view, vibration, correction continuity, or EMI breaks FIX during dynamic flight. |
|---|---|
| Recommended UM982 Setup | UM982 receiver, lightweight multi-band antenna, clean power, logged correction age, and host integration that records raw GNSS and fix state. |
| Antenna / Baseline Notes | Use one clear-sky antenna for positioning; evaluate dual antennas only when airframe size supports a rigid heading baseline. |
| Correction Strategy | NTRIP for connected flights; local base or PPK fallback for field sites with weak coverage. |
| Field Checklist | Record C/N0, correction age, fix state, flight attitude, antenna photos, RF cable routing, and power source. |
| Success Experience | Most drone RTK improvements come from antenna placement, vibration isolation, and correction logging before changing receiver settings. |
