Meridian M1 Air — GNSS Antenna for Agricultural Drones

Meridian M1 Air is the lightest antenna in the Meridian line, built for airborne platforms where every gram is taken out of the payload budget. It is intended for agricultural spraying drones and for survey and field-monitoring flights, where the position solution has to stay just as good on the last swath as on the first.

The radome is a single moulded piece over a slim machined base ring, so the antenna adds almost no drag and mounts flat to the airframe with a standard bolt pattern. A single connector exits underneath, which keeps the cable run short and out of the propeller wash.

Key Features

• Minimal mass and a low profile, sized for multirotor and fixed-wing payload limits
• Stable phase centre across the full flight envelope, so swath-to-swath repeatability holds
• Multi-band GNSS reception, RTK-ready for centimetre-level guidance
• Flat mounting to the platform frame with a single connector exit underneath
• Sealed one-piece radome, unaffected by spray chemicals, dust and washdown

Applications

Precision spraying

Automated swath control and overlap reduction on agricultural spraying drones.

Field survey

Photogrammetry and multispectral mapping flights that need repeatable georeferencing.

Crop monitoring

Scheduled monitoring routes flown to the same track season after season.
