Separate the controller from the correction base
S3 and S3-A are flight-control products. The RTK Ground Base Station provides ground-side positioning corrections; it does not replace the aircraft flight controller or a compatible airborne receiver.

Compare SKYDROID UAV avionics by controller hardware, navigation role and supported connections. Select the flight controller separately from an RTK correction base station.
S3 and S3-A are flight-control products. The RTK Ground Base Station provides ground-side positioning corrections; it does not replace the aircraft flight controller or a compatible airborne receiver.
Compare aircraft type, firmware, navigation pairing and physical interfaces. S3-A has its own documented GPS-A requirement; similar controller housings do not establish interchangeable firmware or peripherals.
