Real RTK at a fleet-friendly price

The MA-RTK-AIR-626 exists for one reason: when a drone light show or research swarm needs every aircraft to hold a centimeter-grade position, the module cost multiplies by the fleet size. Built on the Unicore UM626N dual-band (L1+L5) receiver, the 626 delivers a true 1.5 cm + 1 ppm RTK FIX on ArduPilot at a fraction of the price of a conventional RTK module — and at only 200 mW it sips power and stays cool packed inside a small airframe.

One MicoAir MA-RTK-BASE station broadcasts corrections to an unlimited number of 626-equipped aircraft — the per-drone cost of centimeter positioning is just this module.
